Front

What is sexual reproduction?

Back

A type of reproduction that involves the combination of genetic material from two parents, resulting in offspring that are genetically diverse.

Front

What is asexual reproduction?

Back

A type of reproduction that involves only one parent, producing offspring that are genetically identical to the parent.

Front

What is genetic diversity?

Back

The variety of genes within a species, which is increased through sexual reproduction.

The observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is a genotype?

Back

The genetic constitution of an individual, representing the specific alleles inherited from the parents.

Front

What is a dominant trait?

Back

A trait that is expressed in the phenotype even when only one copy of the allele is present.

Front

What is a recessive trait?

Back

A trait that is only expressed in the phenotype when two copies of the allele are present.
