Abstract
Disclosed is a mankind chromosome segregation combination demonstration device, comprising a composite board 1 and a composite board 2, wherein the composite board 1 is composed of a transparent board 1 arranged at the upper surface and a transparent board 2 arranged at the lower surface, with both being glued with pasters 1 representing chromosome; the pasters 1 are cut into the shape of chromosome in male, with two pasters of the pair being respectively glued to the transparent board 1 and the transparent board 2; the position of the pasters 1 can ensure the two transparent boards to present complete male chromosome morphology while the two transparent boards are overlaid; the composite board 2 is composed of a transparent board 3 arranged at the upper surface and a transparent board 4 arranged at the lower surface, with both the transparent boards being glued with paster 2 representing chromosome; the pasters 2 are cut into the shape of chromosome in female, with two pasters of the pair being respectively glued to the transparent board 3 and the transparent board 4; and the position of the paster 2 can ensure the two transparent boards to present complete female chromosome morphology while the two transparent boards are overlaid. The mankind chromosome segregation combination demonstration device can enhance the comprehension of the students about the teaching contents.
Description
Technical field
The utility model relates to the human chromosomal separation combined demonstrater that a kind of education and instruction is used.
Background technology
When study human chromosomal and Sex Determination, existing teaching aid is exactly picture.It belongs to static, the very difficult embodiment intuitively of process that separates and make up.The student is difficult to the paired existence of understanding human chromosomal, and in acquiring people's reproductive process, by special division, make chromosome paired in body cell separated from one another, form and respectively contain 23 chromosomal reproduction cell, last reproduction cell is combined into again and is subjected to ovum, and chromosome returns to again 23 pairs.The student understands more difficult.
Summary of the invention
In order to have overcome the shortcoming of existing teaching equipment, provide a kind of human chromosomal intuitively to separate combined demonstrater, can make the student deepen understanding to the content of courses.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of human chromosomal separates combined demonstrater, comprise composite plate one and composite plate two, it is characterized in that: composite plate one is by being placed in top transparent panel one and underlaid transparent panel two forms, two transparent panels all post and represent chromosomal paster 1, paster 1 is cut into the chromosomal shape of the male sex, any one in every a pair of paster is attached to respectively on transparent panel one and transparent panel two, and the position of paster 1 presents complete male sex's chromosome morphology in the time of can guaranteeing two transparent panel stacks; Composite plate two is by being placed in top transparent panel three and underlaid transparent panel four forms, two transparent panels all post and represent chromosomal paster 2, paster 2 is cut into the shape of female chromosome, any one in every a pair of paster is attached to respectively on transparent panel three and transparent panel four, and the position of paster 2 presents complete female chromosome form in the time of can guaranteeing two transparent panel stacks.
Transparent panel one, transparent panel two, transparent panel three and transparent panel four adopt PV three transparent materials, and paster 1 and paster 2 are made of the different colours Sticky Note respectively.
Described the utility model has the advantages that:
The utility model has embodied the process of separation and the combination of gene with solid teaching aid intuitively, and the student can operate, relatively more directly perceived and dynamic representation the separation of gene and the process of combination, teaching efficiency obviously improves.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of transparent panel one of the present utility model and transparent panel two.
Fig. 3 is the structural representation of the utility model transparent panel three and transparent panel four.
In accompanying drawing: 1, paster; 2, paster; AB, composite plate one; CD, composite plate two; A, transparent panel one; B, transparent panel two; C, transparent panel three; D, transparent panel four.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
A kind of human chromosomal separates combined demonstrater, comprise composite plate one and composite plate two, it is characterized in that: composite plate one is by being placed in top transparent panel one and underlaid transparent panel two forms, two transparent panels all post and represent chromosomal paster 1, paster 1 is cut into the chromosomal shape of the male sex, any one in every a pair of paster is attached to respectively on transparent panel one and transparent panel two, and the position of paster 1 presents complete male sex's chromosome morphology in the time of can guaranteeing two transparent panel stacks; Composite plate two is by being placed in top transparent panel three and underlaid transparent panel four forms, two transparent panels all post and represent chromosomal paster 2, paster 2 is cut into the shape of female chromosome, any one in every a pair of paster is attached to respectively on transparent panel three and transparent panel four, and the position of paster 2 presents complete female chromosome form in the time of can guaranteeing two transparent panel stacks.
Be illustrated in figure 2 as composite plate state after a separation.Be illustrated in figure 3 as the state after composite plate two is separated.The chromosome morphology that male germ cell is pressed in transparent panel one, transparent panel two representatives, the chromosome morphology that female reproductive cell is pressed in transparent panel three, transparent panel four representatives.
What transparent panel one was random superposes with transparent panel three and transparent panel four, presents the chromosome morphology of embryonated egg; What transparent panel two was random superposes with transparent panel three and transparent panel four, presents the chromosome morphology of embryonated egg.
Transparent panel one, transparent panel two, transparent panel three and transparent panel four adopt PV three transparent materials, and paster 1 and paster 2 are made of the different colours Sticky Note respectively.The different colours Sticky Note is used for the chromosome of difference masculinity and femininity.
The utility model can be seen chromosomal paired existence intuitively, separated from one another when forming reproduction cell, chromosomal reconfiguring when forming embryonated egg, and can see that from different colors our sex chromosome is one and comes from father, article one, come from mother, can also obtain giving birth to boy student woman chance is impartial conclusion.
The utility model has embodied the process of separation and the combination of gene with solid teaching aid intuitively, and the student can operate, relatively more directly perceived and dynamic representation the separation of gene and the process of combination, teaching efficiency obviously improves.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and protection domain are limited; under the prerequisite that does not break away from the utility model design concept; various modification and improvement that in this area, common engineering technical personnel make the technical solution of the utility model all should fall into protection domain of the present utility model.
