Question

linked genes due to physical linkage are:

a) found in the same species

b) genes on different chromosomes but in the same nucleus

c) found on the sex chromosome only (X or Y chromosomes)

d) genes on the same chromosome

e) restored to linked over time by recombination

there's more than one option correct. choose the correct answers

Answer 1

Linked genes are those genes which are located on the same chromosome. So they are inherited together and their phenotypes are often found together.

linked genes are found in the same species and inherited together this was explained by mendal.

So option a is correct.

Linked genes are close together on the same chromosome and not on the different chromosomes.

So option b is incorrect.

Sex linked is a trait in which a gene is located on a sex chromosome. Linked genes are present only on the X chromosome and not the Y chromosome.

So option c is incorrect.

linked genes are found on the same chromosome .

So option d is correct.

Linkedd genes can be separated by recombination. The process of recombination or crossing over occurs when two homologous chromosomes align during meiosis and exchange a segment of genetic material takes place so linked genes can not restored by recombination.

So e option is incorrect.
