Mendelian & Non-Mendelian Genetics

Front

What is incomplete dominance?

Back

A genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype that is a blend of the two traits.

Front

What are alleles?

Back

Different forms of a gene that can exist at a specific locus on a chromosome.

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

Define heterozygous.

Back

A genotype consisting of one dominant and one recessive allele for a particular trait (e.g., Bb).

Front

What is the genotype for a red carnation in codominance?

Back

RR (homozygous dominant for red color).

Front

What is the genotype for a white carnation in codominance?

Back

WW (homozygous dominant for white color).

Front

What is the genotype for a speckled carnation in codominance?

Back

RW (heterozygous, showing both red and white traits).

Front

What is dominance in genetics?

Back

A relationship between alleles of a gene, where one allele masks the expression of another allele.

Front

What is a phenotype?

Back

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

Front

What is a genotype?

Back

The genetic constitution of an individual, specifically the alleles present at a given locus.
