explain how fertilization causes genetic variation?​

Sagot :

Answer:

Random fertilization increases genetic diversity.

When a male gamete and a female gamete finally meet, each is the result of an immense number of genetic possibilities created during independent assortment and crossing over. Human diploid cells have 23 pairs of chromosomes.

Answer:

Genetic variation is increased by meiosis.

=>During fertilisation, 1 gamete from each parent combines to form a zygote. Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote.
