Explanation:

Complete question

In tooth fairies, curved wings are dominant over straight wings. If a homozygous recessive tooth fairy has 4 children, and half of them have straight wings

a.) Gene=

b.) Alleles=

c.) Mother's Genotype=

d.) Genotype of her tooth fairy husband=

e.) Genotype of the other 2 children=

Solution -

Here the allele being talked about is the wing type

Thus gene = wing

Let the allele for curved wings be represented by "C"

and the allele for straight wings be represented by "S"

Thus, allele are C and S

Genotype of mother -

Genotype of father is CS

and genotype of mother is SS

CS * SS

CS, CS, SS, SS

Only SS will have straight wings.

Genotype of her tooth fairy husband = CS

Genotype of other two children - CS
