Which process is least likely to add to the variety of traits in a population?

A. Genetic engineering

B. accurate replication of DNA

C. deletion of bases of DNA

D. exchange of segments between chromosomes

B. accurate replication of DNA

Explanation:

DNA contain genetic information of the organism that define traits of the organism and subsequently traits of the Population.

Genetic engineering changes the Sequence of DNA and thus cause the variety in traits. Deletion bases would also lead to alteration in DNA and exchange of segments between chromosomes is known as crossover which is essential for variety of traits.

Accurate replication would produce the same traits in a population so it is least likely to add variety of traits.

i think a) betsy can donate only blood to mark is correct because, mark and betsy have the same blood type. whereas nobody else has b+ blood so betsy can't donate to them.

i think its y= -4x-14
