Vedclass · Answer

(C) In humans,the trait for curly hair is dominant $(C)$ and the trait for straight hair is recessive $(c)$.Assuming the mother is homozygous dominant $(CC)$ and the father is homozygous recessive $(cc)$,all offspring will be heterozygous $(Cc)$ and exhibit curly hair.However,if the mother is heterozygous $(Cc)$ and the father is homozygous recessive $(cc)$,the cross is $Cc 	imes cc$.The resulting genotypes are $Cc$ (curly) and $cc$ (straight) in a $1:1$ ratio.For $8$ children,the expected distribution is $4$ curly-haired and $4$ straight-haired,resulting in a ratio of $4:4$.

As a result of the marriage between a curly-haired mother and a straight-haired father,$8$ children are born. What is the expected ratio of curly-haired to straight-haired children?
