Question

1. some dragons have triangle scales (t) and others have rounded scales (t). 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: Set up the 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: Analyze the offspring genotypes

From the Punnett square, the genotypes of offspring are \( Tt \) and \( tt \). The proportion of \( tt \) (rounded scales) is \( \frac{1}{2} \).

Step4: Convert proportion to percentage

To convert \( \frac{1}{2} \) to a percentage, we use the formula \( \text{Percentage}=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\times100\% \). So \( \frac{1}{2}\times100\% = 50\% \).

Answer:

50%
