Front

What are DOMINANT alleles?

Back

Alleles that are expressed when at least one is present.

Front

What is the probability of a pink offspring in a cross between a white (recessive) and red (dominant) flower?

Back

50%.

Front

What does it mean if genes for two traits are located close together on the same chromosome?

Back

It suggests that crossing over occurred between the two gene loci.

Front

What are the possible genotypes for bees with long wings (L)?

Back

Heterozygous (Ll) or homozygous dominant (LL).

Front

What is an example of Codominance?

Back

Black and white checkered chickens.

Front

Define Incomplete Dominance.

Back

A genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype.

Front

What is the principle of Independent Assortment?

Back

The principle stating that genes for different traits are inherited independently of each other.

Front

What is a genotype?

Back

The genetic constitution of an individual, represented by alleles.

Front

What is a phenotype?

Back

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

Front

What is a homozygous genotype?

Back

A genotype consisting of two identical alleles for a particular gene.
