<h2>D) is the correct option </h2>
Explanation:
Northern elephant seal is an example of bottleneck effect
In bottleneck effect the elimination of inferior genotype from a homogeneous gene pool occurs due to the strong natural selection pressure and changing environmental conditions which leads to the genetic drift and only a few most adapted genotype survives and flourish
In case of Northern elephant seal, due to hunting a population decline occurred, environmental conditions changed as a result few genotypes homozygous for every gene is present
Both Gene and Chromosomal mutations. They can change a DNA sequence and affect generic information. Gene mutations change several nucleotides, where chromosomal mutations can change the number or structure of a whole chromosome.
Answer:
.
Explanation:
Enzymes are proteins that act as biological catalysts. Catalysts accelerate chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products
