(100 points .) the punnett square shows alleles for hairline type among one parent and the possible allele frequencies among the children. the dominant form of this trait is a widows peak (p), and the recessive form is a straight hairline. the alleles for one parent are missing.

what are the alleles for the missing parent?

pp

Explanation:

Given, that parent 1 is Pp and allele makeup among children is Pp, pp, Pp and pp

If parent 2 is pp then their progeny:

Pp X pp :

    P     p

p  Pp   pp

p  Pp   pp

The possible allele makeup among children will be Pp, pp, Pp and pp which is the same as the one given in question. Hence, alleles for the missing parent are pp.

where is the diagram?

if you insert the diagram ill be able to you
