In dragons, the allele for fire breathing (F) is dominant over the allele that codes for a non-fire breather (f).

If you cross a female dragon that is a hybrid with a male dragon that is purebred recessive, what is the probability of producing an offspring that will breathe fire?

To calculate the probability of producing an offspring that will breathe fire, we need to analyze the genotypes of the parents.

A hybrid female dragon has the genotype of Ff, where F represents the dominant allele for fire breathing and f represents the recessive allele for non-fire breathing.

A purebred recessive male dragon would have the genotype of ff, where both alleles are recessive.

When these two dragons reproduce, their possible combinations are:
Ff x ff

To determine the probability of each outcome, we can use a Punnett square:

f f
--------------
F | Ff Ff
--------------
f | ff ff

From the Punnett square, we can see that there is a 50% chance (2 out of 4 possibilities) of producing an offspring with the genotype Ff, which means it will breathe fire.

Therefore, the probability of producing an offspring that will breathe fire is 50%.
