The brown skin trait is dominant over the black skin trait in cows. If two heterozygous brown skin cows are crossed, what is the brown-skinned offspring?

B = Brown Skin

b = black skin

                             B      b

                  B        BB   Bb

                  b         Bb   bb

Hope this helped :D

The chances of a homozygous brown skin cow is 25%

The chances of a heterozygous brown skin cow is 50%

The chances of a homozygous black skin cow is 25%

The chances of a heterozygous black skin cow is 0%

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
