Question

Before Dobby the house elf became a servant for the Malfoy family, he met Viola. He considered Viola to be the most beautiful

house elf he had ever seen and he fell in love with her large green round eyes. Unfortunately house elves are not allowed to

mamy once they serve a master, and Viola was a servant for the Longbottom family, Draw a punnett square to show the

possible eye shapes their children could have had if they were able to marry. Dobby is homozygous for his large round eyes,

but Viola is heterozygous. (Use the genotypes from above)

Answer 1

a)

RR * Rr

RR, RR, Rr, Rr

b)
`100` %

c)
`0` %

Step-by-step explanation:

Given -

Dobby has large round eyes with homozygous genotype while Viola is heterozygous for the same.

Let us assume that

"R" represents the allele for large round shaped eyes

and "r" represents the allele for other than round shaped eyes

Thus, the genotype for Dobby would be "RR"

and the genotype of Viola would be "Rr"

a)

When Dobby and Viola mate, following offspring are possible

RR * Rr

RR, RR, Rr, Rr

All the offspring will have pehnotypically large round eyes. However, genotypically, half of the total offspring are homozygous for large round eyes and remaining half are heterozygous for large round eyes.

b)
`100` %

Out of
`4` all
`4` will have round eyes.

c)
`0` %
