## What are the genotype probabilities of the offspring?

In a monohybrid cross, where the allele *s present in both parents are known, each genotype * shown in a Punnett Square * is equally likely to occur. Since there are four boxes in the square, every offspring produced has a one in four, or 25%, chance of having one of the genotypes shown.

## What is the probability percentage of offspring?

Divide the number of boxes with a dominant allele by four and multiply the result by 100 to get the percent chance that an offspring will have the dominant trait. For example (2/4)*100 = 50, so there is a 50 percent chance of an offspring having brown eyes.

## What are the genotype and phenotype of the offspring?

Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.

## What is the probability of an offspring being female?

Each time a sperm meets an ovum, there is a 50% chance that it will make a boy and a 50% chance that it will make a girl.
