Question

Suppose chromosome Ace includes the gene for hair texture, chromosome 2 has a gene for eye color, and chromosome 3 has a gene for nose width with the traits for each shown in the table. BLACK cards carry the dominant allele and RED cards carry recessive allele.

Character	Traits	Allele
Hair texture	Dominant-curly Recessive-straight	H h
Eye color	Dominant-brown Recessive-blue	E e
Nose width	Dominant-wide Recessive-narrow	N n

1. Using the table above, rewrite SueBob’s genotype.

2. Describe Baby SueBob’s phenotype.

3. When SueBob grows up, she starts a family with HenryJane. His genotype is HheeNn. Describe HenryJane’s phenotype.

4. Complete a Punnett square to predict the probabilities of hair texture among their children.
