Flashcards in Chapter 6: Genetic Linkage and Mapping in Eukaryotes Deck (10)
when two or more genes are located on the same chromosome
genes that are close together on the same chromosome tend to be transmitted as a unit, influencing inheritance patterns
synonymous with chromosome, because chromosomes contain a group of genes that are physically linked together
how many linkage groups do humans have?
Humans have 22 autosomal linkage groups, and an X chromosome linkage group, and males have a Y chromosome linkage group. In addition, the human mitochondrial genome is another linkage group.
also called a tetrad, two pairs of sister chromatids joined in crossing over
an event leading to new combinations of alleles
also called recombinant cells, a product of crossing over in which linked alleles are reassorted, producing cells that do not share the same combination of alleles found in the chromosomes of their parents
also called nonparental cells, a product of crossing over in which linked alleles are reassorted, producing cells that do not share the same combination of alleles found in the chromosomes of their parents
also called non recombinant offspring, offspring that have inherited the same combination of alleles that are found in the chromosomes of their parents
