Inheritance & Genetics Vocab Review

A specific characteristic passed from parent to offspring

A gene with more than two alleles; ABO blood type

A sequence of DNA that codes for a protein and determines a specific trait

Occurs when male and female reproductive cells join to produce a new cell (zygote).

Offspring of crosses between parents with different traits (purple vs white flowers)

Occurs when both alleles are clearly expressed in the phenotype.

The separation of alleles; occurs during meiosis

Occurs when the heterozygous phenotype is somewhere between the two homozygous phenotypes; produces a blending

Uses probability to help predict the genotype and phenotype combinations in genetic crosses

The likelihood that a particular event will occur

States that some alleles are dominant and some are recessive

Organisms that have two identical alleles for a particular gene; GG or gg

Traits that are controlled by two or more genes; (2-12 genes associated with human eye color)

States that genes for different traits can segregate independently during the formation of gametes

A form of a specific gene

The scientific study of biological inheritance

Reproductive cells made during meiosis; sperm or egg cells

The physical traits of an organism

Organisms that have two different alleles for the same gene; Gg

The genetic makeup of an organism
