Crossing Over

Vedclass · Answer

(C) Genetic variation in sexually reproducing organisms is primarily caused by the process of $Crossing 	ext{ } Over$. During meiosis, specifically in the $Pachytene$ stage of $Prophase-I$, homologous chromosomes exchange segments of genetic material. The frequency of $Crossing 	ext{ } Over$ is directly proportional to the distance between genes on a chromosome. Since longer chromosomes provide more physical space for these exchanges to occur, they facilitate a higher frequency of recombination, leading to increased genetic variation.

The greater the length of the chromosomes in an organism, the greater the genetic variation. This variation is obtained from which of the following processes?

Which is the most common mechanism of genetic variation in the population of a sexually reproducing organism?

The theory of recombination of linked genes due to crossing over of chromosomes during the pachytene stage of meiosis was put forward by:

$A$: Crossing over is the exchange of genetic material between non-homologous chromosomes.
$R$: It produces new linkages.

Assertion: In case of incomplete linkage,linked genes show new combinations along with parental combinations.
Reason: In case of incomplete linkage,linked genes are separated by crossing over.

Why did Mendel face difficulties in explaining linked traits?
