18.2: Determining the likelihood that traits will be inherited together

Vocabulary flashcards based on lecture notes about genetic recombination and linkage. Terms include key concepts like parental arrangement, recombination frequency, cis and trans arrangements, and genetic mapping.

Parental Arrangement

The alleles that occur together on the same chromosome in the parent.

Recombination Frequency

Indication of how closely together 2 genes are based on how frequently recombinant gametes are observed relative to the total number of gametes.

Parental Arrangement

The alleles that occur together on the same chromosome in the parent.

Recombination Frequency

Indication of how closely together 2 genes are based on how frequently recombinant gametes are observed relative to the total number of gametes.

Unlinked Genes

When the frequency of recombinant alleles is 50%, equivalent to independent assortment of genes on different chromosomes, indicating genes are unlinked.

Cis Arrangement

both wild type alleles are on one homologous chromosome and both mutant alleles are on the other homologous chromosome.

Trans Arrangement

When one wild type and one mutant allele are located on one homologous chromosome and the opposite on the other homologous chromosome

Genetic Mapping

Used to determine the likelihood of different phenotypic classes in a cross.
