Question

When I mated two curly-furred beasties, I was struck by the ratio of progeny. Roughly half (99) had curly fur, roughly one quarter (54) had straight fur, and about one quarter (47) were the homely type,

Answer 1

Both are Homozygous

Step-by-step explanation:

A Husband and Wife with curly haired husband(CC) and straight haired wife have all their children curly haired because the gene for curly hair is dominant than straight hair. So, in the progeny, curly hair only.

This represents the Mendel’s Law of dominance which is also the Mendel Third Law which states that one of the factors for a pair of inherited traits will be dominant and the other recessive, unless both factors are recessive.

So, the correct option is ‘Both are homozygous'.
