Ответ:
a.) Gene= Wings
b.) Alleles= C,S
c.) Mother's Genotype= SS
d.) Genotype of her tooth fairy husband= CS
e.) Genotype of the other 2 children= CS
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
