Gene Mapping and Test Crosses

Flashcards covering key concepts of gene mapping, test crosses, and genetic terms related to the analysis of traits and genes.

Gene Mapping

The position of genes/loci associated with traits along chromosomes, using recombination frequencies to locate genes relative to one another.

Recombination Frequency

The proportion of offspring that exhibit recombinant phenotypes, used to calculate map units.

Map Units (mu)

A unit measurement in genetics indicating the distance between genes based on recombination frequency.

Test Cross

A cross between an individual with an unknown genotype and a homozygous recessive individual to determine the unknown genotype.

Independently Assorting

The concept that different genes can segregate independently during gamete formation.

Traits

Characteristics or features of an organism, such as color, morphology, or shape.

Gametes

Reproductive cells that carry half the genetic information of an organism, used during reproduction.

F1 Generation

The first filial generation of offspring resulting from a cross of parent organisms.
