How does the sexual life cycle of the human species introduce genetic variations?

Biology
1 answer:
kari74 [83]3 years ago
5 0

Answer:

In humans, genetic variations are caused because humans reproduce by a sexual life cycle which is termed as meiosis. In such a life cycle, the offspring receives half the chromosomes from the mother and half from the father. Crossing over and  random assortment of chromosomes are two phenomenons which occur during meiosis. Due to these two phenomenons, genetic variations are caused.

During crossing over, the exchange of DNA segments between the homologous chromosomes takes place which brings about the genetic variations.
