Ответ:
256
Explanation:
If there are 2 pairs of chromosomes Aa and Bb, there are 4 possibilities for independent assortment of gametes:
A w B, aith with b, A with b and a with B.
If there are 3 pairs of chromosomes Aa, Bb and Cc, there are 8 possibilities:
ABC, abc, ABc, Abc, aBC, aBc, abC, AbC
This corresponds to 2^n, where n= the number of chromosomes.
Therefore, with 8 chromosomes, the possibilities are 2^8 = 256
This is for each parent.
