Question

Recombination occurs through: A. crossing over and chromosome interference B. crossing over and independent assortment. C. complete linkage and chromosome interference. D. somatic-cell hybridization and chromosome interference. E. chromosome interference and independent assortment.

Answer 1

Question:

Recombination occurs through:

A. crossing over and chromosome interference

B. crossing over and independent assortment.

C. complete linkage and chromosome interference.

D. somatic-cell hybridization and chromosome interference.

E. chromosome interference and independent assortment.

Answer:

The correct answer is B) Crossing over and Independent Assortment

Step-by-step explanation:

DNA Recombination refers to the exchange of genetic material either between multiple chromosomes or between different regions of the same chromosome.

When this happens, an offspring posses a different combinations of genes than their parents.

Answer 2

Answer:Recombination occurs through

crossing over and independent assortment. The correct option is B

Step-by-step explanation:

-Genetic recombination is the process by which two different DNA are disintegrated and recombined to form new pairs of alleles. The process of recombination also involves the breakage and rejoining of parental chromosome. It occurs during meiosis ( that is formation of sperm and egg cells) and it gives them the correct number if chromosomes). Recombination occurs in meiosis through:

- CROSSING OVER: this is when paired chromosome press together and break, each may swap a portion of its genetic material.

- INDEPENDENT ASSORTMENT: which is the chromosome invented from either the father or mother can sort into any gamete and this produces a tremendous genetic variation. I hope this helps, thanks!
