Question

A gene has two alleles, E and e. Another gene also has two alleles, T and t. Which of the following correctly shows linkage between the two genes? Group of answer choices Te/Et Ete/T ET/et Ee/tT

Answer 1

Answer: ET/et, Te/Et

Explanation:

Gene linkage is the ability of DNA sequences that are close together usually on a chromosome to be inherited together.

during the meiosis in sexual reproduction two genes that are physically close to each other are not likely to separate from each other to different chromatids during chromosome crossover but are rather linked and inherited together. Genes that are close on the chromosome are said to be more linked than gene that are far apart.

If two genes on a chromosome are close there is low chance of recombination between them, and they are likely to be inherited together. Gene on different chromosomes are not linked.

Answer 2

Answer: ET/et and also Te/Et

Explanation:

When genes are on separate chromosomes, they tend to assort independently meaning that due to the random position/placement of the homologous chromosomes pair on the metaphor plate during meiosis, the homologous chromosomes assort independently.
