Question

1. a mom monster has homozygous recessive alleles for no horns (h). cross her alleles with a dad monster who has homozygous dominant alleles.

a. what percentage of dragons have horns? 100%
b. what genotypes appear from this cross? hh

Explanation:

Step1: Determine the parents' genotypes

The mom monster has homozygous recessive alleles for no horns, so her genotype is \( hh \). The dad monster has homozygous dominant alleles, so his genotype is \( HH \).

Step2: Create a Punnett square

	\( H \)	\( H \)
\( h \)	\( Hh \)	\( Hh \)

Step3: Analyze the results for part A

All offspring have the genotype \( Hh \). Since the dominant allele \( H \) (for horns) masks the recessive allele \( h \), 100% of the offspring will have horns.

Step4: Analyze the results for part B

Looking at the Punnett square, all of the offspring have the genotype \( Hh \).

Answer:

A. 100% of dragons have horns.
B. The genotype \( Hh \) appears from this cross.
