katrin [286]

1) As blood groups A and B are equally dominant so the individual will express both characteristics in the phenotype.
Notice how in all the 3 other examples the organism is only expensive 1 version (allele) of each gene. For example the mouse with brown fur may have 2 brown fur alleles (and so would have to express this characteristic even if it was recessive) but it could have 1 allele which is less dominant than the brown, in which case brown would be expressed. In this case the alleles were not co-dominant.

Answer:

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.
