In a species of bird, F is the dominant allele for white feathers, and f is the recessive allele for gold feathers. Two birds have four offspring. Three have white feathers, and one has gold feathers. Which of the following could describe the genotypes of the parents?
What is both parents are heterozygous. one allele is dominant while the other is recessive. Ff.
200
2 different alleles. Bb.
What is heterozygous
200
different forms of genes.

a tool that can be used in order to predict traits of the offspring based on probability
What is Punnet squares.

Why is learning about genetics important?
Because without reproduction no species would survive.
400
the study of how traits are passed from parents to offspring’s.
