the punnett square predicts the ratio of genotypes in the offspring based on the genotypes of the parents. which punnett square represents a cross between a mom who is heterozygous for dimples and a dad who is homozygous for no dimples?\nd d\nd dd dd\nd dd dd\n\nd d\nd dd dd\nd dd dd
Answer
Explanation:
Step1: Identify parent genotypes.
The mom is heterozygous for dimples (Dd). The dad is homozygous for no dimples (dd). Let D be the allele for dimples and d be the allele for no dimples. Mom's genotype: $Dd$ Dad's genotype: $dd$
Step2: Set up the Punnett square.
Place the alleles for one parent across the top and the alleles for the other parent down the side. Mom's alleles (D, d) across the top. Dad's alleles (d, d) down the side.
D d
d | Dd | dd |
d | Dd | dd |
Step3: Compare with the options.
The second Punnett square shows the alleles D and d across the top (representing the heterozygous mom) and the alleles d and d down the side (representing the homozygous dad). The resulting offspring genotypes (Dd, dd, Dd, dd) match the cross.
Answer:
The second option represents the correct Punnett square:
| D | d | |
|---|---|---|
| d | Dd | dd |
| d | Dd | dd |
