Question

1. dragons with spikes on their tails (s) are dominant to dragons with hammer tails (s). cross a heterozygous mom with a heterozygous dad.

a. what percentage of the dragon offspring will have spikes on their tails?
b. what percentage of dragon offspring will have hammer tails?

Explanation:

Step1: Determine the genotypes of the parents

The heterozygous mom has genotype \( Ss \), and the heterozygous dad has genotype \( Ss \).

Step2: Create a Punnett square

	\( S \)	\( s \)
\( s \)	\( Ss \)	\( ss \)

Step3: Analyze the phenotypes

• For spikes (dominant trait): \( SS \), \( Ss \), \( Ss \) show spikes. There are 3 out of 4 offspring with spike - related genotypes.
• For hammer tails (recessive trait): Only \( ss \) shows hammer tails. There is 1 out of 4 offspring with the \( ss \) genotype.

Answer:

A. \( 75\%\)
B. \( 25\%\)
