What is complete dominance in genetics?

Back

Complete dominance occurs when one allele completely masks the effect of another allele for a trait.

Front

What shape represents a male in a pedigree chart?

Back

Square.

Front

What does the Law of Independent Assortment state?

Back

The alleles for different traits are sorted separately and do not affect one another.

Front

What is the Law of Segregation?

Back

Every organism has two alleles which separate when gametes are produced.

Front

What is incomplete dominance?

Back

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

Front

What is codominance?

Back

Codominance occurs when both alleles in a heterozygous organism contribute to the phenotype, resulting in a third phenotype.

Front

Define allele.

Back

An allele is a variant form of a gene that can produce different traits.

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, consisting of the alleles inherited from its parents.

Front

What is a phenotype?

Back

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

Front

What is a homozygous genotype?

Back

A homozygous genotype has two identical alleles for a particular gene.
