Unequal crossing over during prophase i can result in one sister chromosome with a deletion and another with a duplication. a mutated form of hemoglobin, so-called hemoglobin lepore, exists in the human population. hemoglobin lepore has a deleted series of amino acids. if this mutated form was caused by unequal crossing over, what would be an expected consequence?

Unequal crossing over during prophase i can result in one sister chromosome with a deletion and another with a duplication. a mutated form of hemoglobin, so-called hemoglobin lepore, exists in the human population. hemoglobin lepore has a deleted series of amino acids. if this mutated form was caused by unequal crossing over, what would be an expected consequence?

Arely Meza · Answer 1

The expected consequences due to unequal crossing over are as follows

Presence of a person whose hemoglobin contain two copies of series of amino acid that is deleted in hemoglobin lepero.

unequal crossing over is type of gene deletion event that delete a sequence in one strand and replace t with a duplicate from sister chromatid.

Rene · Answer 2

Based on the hypothesis above, the best answer for this question would be:

B) There should also be persons whose hemoglobin contains two copies of the series of amino acids that is deleted in hemoglobin Lepore.

This is mostly cause by the genetic mutation in the process.
