Question

1. some dragons have triangle scales (t) and others have rounded scales (f). mom has homozygous alleles for rounded scales, and dad has heterozygous alleles.

a. what percentage of the dragon offspring will have rounded scales?

Explanation:

Step1: Determine the genotypes of parents

Mom has homozygous alleles for rounded scales, so her genotype is \( tt \). Dad has heterozygous alleles, so his genotype is \( Tt \).

Step2: Create a Punnett square

The possible gametes from mom are all \( t \). The possible gametes from dad are \( T \) and \( t \).
The Punnett square is:

	\( T \)	\( t \)

Step3: Calculate the percentage

Out of 2 possible genotypes (\( Tt \) and \( tt \)), 1 has rounded scales (\( tt \)). The percentage is \(\frac{1}{2}\times100\% = 50\%\)

Answer:

50%
