Question

1) Patrick and his partner Patricia recently had Lil Patty and Patricia is worried that the hospital made a mistake and mixed her baby with some other starfishes. Lif Patty has a SMALL HEAD! Patrick is heterozygous for his tall head and Patricia is heterozygous for her tall head. Create a Punnett square using H for the dominant gene and h for the recessive one.

1) Phenotype:

2) Genotype:

3) Phenotypic Ratio:

4) Genotypic Ratio:

Answer 1

Patrick - TT

Patricia - Tt

Outcomes

Tt, Tt, TT, TT

Provided

Patrick is homozygous for tall head

Patricia is heterozygous for her tall head

The little baby Patty has a short head

Let us assume that the traits for short head is represented by "T" and trait for tall head is represented by "t"

Genotype of Patrick is "TT"

and genotype of Patricia is "Tt"

On crossing Patrick and Patricia, following offspring are produced -

TT * Tt

Tt, Tt, TT, TT

Out of four two are heterozygous tall headed and two are homozygous short headed.
