What is the definition of homozygous dominant?

Back

An organism with two identical dominant alleles for a trait (e.g., TT).

Front

What is the definition of phenotype?

Back

The physical expression or characteristics of a trait in an organism.

Front

What are traits in genetics?

Back

Physical characteristics of an organism, such as eye color or height.

Front

What is an allele?

Back

A version of a gene that determines a specific trait.

Front

What is the definition of heterozygous alleles?

Back

An organism with two different alleles for a trait (e.g., Tt).

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup (e.g., TT, Tt), while phenotype refers to the observable traits.

Front

What is a dominant trait?

Back

A trait that is expressed when at least one dominant allele is present.

Front

What is a recessive trait?

Back

A trait that is only expressed when two recessive alleles are present.

Front

What is the role of genes in heredity?

Back

Genes are units of heredity that carry information for traits from parents to offspring.

Front

What is the significance of Punnett squares?

Back

Punnett squares are used to predict the genetic outcomes of a cross between two organisms.
