Answer:

Topoisomerase

Explanation:

Topoisomerases are enzymes that produce changes in the topology of the DNA during replication, transcription, traduction, or reparation processes. They can cut one or both strands and in order to relieve torsional stresses in the supercoiled structure of DNA. With this, they help to maintain the chromosome's integrity. There are two types of topoisomerases: topoisomerase I (it cuts only one strand of DNA) and topoisomerase II (it is able to cut both strands of DNA).

Brown hair is dominant over red hair. What will the genotypes and phenotypes of the offspring of a cross between a homozygous br
beks73 [17]

Answer:

1) The alleles for homozygous brown hair will be BB.

2) The alleles for heterozygous brown hair will be Bb

3) Let's make a punnet square to check for the outcomes:

       B          b

B   BB        Bb

B    BB       Bb

4) The results from the punnet square depict that the phenotype of all the children produced will be brown hair.

5) The punnet square depicts that there will be a 50% probability of the child to carry the heterozygous genome (Bb) and there is also 50% probability for the child to carry homozygous dominant genome (BB).
