Question

1. dragons use teeth to eat their food. some dragons have one row of teeth (r) and some have two rows (r). create a homozygous dominant mom with a homozygous dominant dad.

a. what percentage of offspring will have two rows of teeth?

Explanation:

Step1: Determine the genotypes of parents

A homozygous dominant mom has genotype \( RR \), and a homozygous dominant dad has genotype \( RR \).

Step2: Create a Punnett square

The Punnett square for \( RR\times RR \) is:

	R	R
R	\( RR \)	\( RR \)

Step3: Analyze the offspring genotypes

All offspring have the genotype \( RR \). Since the trait for two - row teeth is recessive (\( rr \)), and there are no \( rr \) offspring.

Answer:

\( 0\% \)
