Genotype and Phenotype Flashcard Review

Front

What is the definition of phenotype?

Back

Phenotype refers to the observable physical characteristics or traits of an individual, which result from the interaction of its genotype with the environment.

What does the genotype 'mm' indicate about an individual's breeding?

Back

The genotype 'mm' is also referred to as 'Purebred', indicating that the individual is homozygous for that trait.

What is the difference between homozygous and heterozygous genotypes?

Back

Homozygous genotypes have two identical alleles for a trait (e.g., 'MM' or 'mm'), while heterozygous genotypes have two different alleles (e.g., 'Bb').

What is the significance of dominant and recessive alleles in determining phenotype?

Back

Dominant alleles mask the effect of recessive alleles in determining phenotype; thus, a dominant allele will determine the phenotype even if only one copy is present.

Front

How can environmental factors influence phenotype?

Back

Environmental factors such as nutrition, climate, and exposure to toxins can affect the expression of genes and thus influence an individual's phenotype.
