Back

The phenotype is blue.

Back

There are no white rabbit babies because it takes two recessive genes to show the trait.

Front

In pea plants, if the tall allele is dominant to the short allele, how are they represented?

Back

Front

What is the difference between homozygous and heterozygous genotypes?

Back

Homozygous genotypes have two identical alleles, while heterozygous genotypes have two different alleles.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is a genotype?

Back

A genotype is the genetic constitution of an individual, specifically the alleles present for a particular gene.

Front

What does it mean for an allele to be dominant?

Back

A dominant allele is one that expresses its trait even when only one copy is present in the genotype.

Front

What does it mean for an allele to be recessive?

Back

A recessive allele only expresses its trait when two copies are present in the genotype.
