Modern Genetics

A trait controlled by genes on one of the 22 pairs of human autosomes.

• autosomal trait
• antigens
• sex-linked trait
• polygenic trait

An acronym that stands for bacterial artificial chromosome.

• BAC
• autosomal trait
• antigens
• sex-linked trait

An individual who has a recessive allele of a gene that does not have effect on their phenotype, they are heterozygous.

• carrier
• BAC
• autosomal trait
• antigens

The study of heritable phenotype changes that do not involve alterations in the DNA sequence.

• epigenetics
• carrier
• BAC
• autosomal trait

When one gene depends on another gene to be expressed.

• epistasis
• epigenetics
• carrier
• BAC

The complete set of genetic information in an organism. It provides all of the information the organism requires to function.

• genome
• epistasis
• epigenetics
• carrier

Proteins that help to wrap DNA to make the chromosomes easy to move during mitosis or meiosis.

• histones
• genome
• epistasis
• epigenetics

A genetic pattern where a dominant allele does not completely mask the effects of a recessive allele, and the organism's resulting physical appearance shows a blending of both alleles.

• incomplete dominance
• histones
• genome
• epistasis

The addition of a methyl group, or a "chemical cap," to part of the DNA molecule, which prevents certain genes from being expressed

• methylation
• incomplete dominance
• histones
• genome

Genetic representation of a family tree that diagrams the inheritance of a trait or disease though several generations.

• pedigree
• methylation
• incomplete dominance
• histones
