What Are Genotypes and Phenotype Genotype

Phenotypes? Black fur BB

A genotype is an organism’s collection of Black fur Bb
genes. It also refers to the alleles inherited for
a particular gene. A phenotype, on the other White fur bb
hand, is an organism’s observable traits, such
as fur color, eye color and height, among
others.

If a dominant allele is present, then the
phenotype will always be the dominant trait. BB Bb bb
A phenotype will be the recessive trait when
two copies of the recessive allele are present.

BB x bb Cross

In this Punnett square, the parental cross results in offspring with only one allele combination.
All the offspring would have the same genotype and phenotype.
