What is heredity?

Back

Heredity is the passing of traits from parents to offspring through genes.

Front

What is a homozygous dominant genotype?

Back

A homozygous dominant genotype has two identical dominant alleles, such as GG.

Front

What is a recessive trait?

Back

A recessive trait is a trait that can be masked by a dominant trait and may reappear in later generations.

What does the genotype Bb indicate about a squirrel's fur color?

Back

The genotype Bb indicates that the squirrel has brown fur, as brown (B) is dominant over gray (b).

Front

What is the difference between dominant and recessive traits?

Back

Dominant traits are expressed when at least one dominant allele is present, while recessive traits are only expressed when two recessive alleles are present.

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the alleles it possesses.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What does it mean for a trait to be true-breeding?

Back

A true-breeding trait is one that consistently produces offspring with the same phenotype when self-fertilized.

Front

What is the significance of the Punnett square in genetics?

Back

A Punnett square is a tool used to predict the genotypes and phenotypes of offspring from a genetic cross.

Front

What is the role of alleles in genetics?

Back

Alleles are different forms of a gene that determine specific traits in an organism.
