Crossing end is a procedure that occurs throughout the meiosis (prophase 1) and also represents the exchange of hereditary material between non-sister chromatids the homologous chromosomes. As a an outcome of this process brand-new recombinant chromosomes (new allelic combinations in the daughter cells) room formed. Crossing end is a source of hereditary variation.

You are watching: Recombinant chromosomes have a mix of paternal and maternal alleles due to

Crossing over

Explanation:

At so late Prophase ns of meiosis homologous chromosomes are pair by synapsis, and lie side by side to kind a bivalent.

Genetic components present in each homologue overcome to the various other at the allude of contacts of the arms of chromosomes(chiasmata) with each other. The arms or components of the chromatids might break and rejoined through the other chromatids, aiding mix up. The suggest of the exchange of hereditary material is referred to as chiasma. Plura chiasmata,

Therefore genetic materials native the 2 bivalent pair acquire exchanged or blended with one another. This is called crossing over. And also it develops the communication of chromosomes recombination due to the fact that assuming the sister chromatids (bivalent)were from fathers and mothers, the exchange of hereditary materials ensures chromosomes shuffles which gives rooms because that variation
