Front

What are genotypes?

Back

Genotypes are the genetic makeup of an organism, represented by the combination of alleles (e.g., Aa, DD, Ba, yy).

Front

What genotype would an organism with white fur have if black fur is dominant?

Back

The organism would have the genotype 'ff' for white fur, as it must have two recessive alleles.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup, while phenotype refers to the observable traits of an organism.

Front

What is a dominant trait?

Back

A dominant trait is a characteristic that is expressed in the phenotype even when only one allele is present.

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene (e.g., AA or aa).
