Crossing Over in Cell Division

Crossing over is a significant event that occurs during meiosis, a type of cell division that forms gametes. During crossing over, the paternal and maternal chromosomes exchange genetic material with each other. This process contributes to genetic diversity in offspring.

Process of Crossing Over

Crossing over occurs during prophase I of meiosis. During this stage, homologous chromosomes pair up and form a structure called a bivalent or tetrad. Crossing over occurs when two non-sister chromatids, one from each homologous chromosome, exchange genetic material. This exchange occurs at specific points along the chromatids called chiasmata.

Significance of Crossing Over

Crossing over is significant because it contributes to genetic diversity in offspring. The exchange of genetic material between homologous chromosomes creates new combinations of alleles that were not present in the parent cells. This diversity helps to increase the chances that offspring will survive in changing environments.

Conclusion

Crossing over is an essential process that occurs during meiosis. It involves the exchange of genetic material between homologous chromosomes and contributes to genetic diversity in offspring. This process is significant in evolutionary terms because it helps to increase the chances of survival in changing environments.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same:Negative Refractive Index: One of the most fundamental phenomena in optics is refraction. When a beam of light crosses the interface between two different materials, its path is altered depending on the difference in the refractive indices of the materials. The greater the difference, the greater the refraction of the beam. For all known naturally occurring materials the refractive index assumes only positive values. But does this have to be the case?In 1967, Soviet physicist Victor Veselago hypothesized that a material with a negative refractive index could exist without violating any of the laws of physics.Veselago predicted that this remarkable material would exhibit a wide variety of new optical phenomena. However, until recently no one had found such a material and Veselago’s ideas had remained untested. Recently, meta-material samples are being tested for negative refractive index. But the experiments show significant losses and this could be an intrinsic property of negativeindex materials.Snell’s law is satisfied for the materials having a negative refractive index, but the direction of the refracted light ray is ‘mirror-imaged’ about the normal to the surface.There will be an interesting difference in image formation if a vessel is filled with “negative water” having refractive index – 1.33 instead of regular water having refractive index 1.33.Say, there is a fish in a vessel filled with negative water. The position of the fish is such that the observer cannot see it due to normal refraction since the refracted ray does not reach to his eye.But due to negative refraction, he will be able to see it since the refracted ray now reaches his eye.Q. When the angle of incidence will be equal to angle of refraction for material having negative refraction index?
