<span>What MUST occur before mitosis and meiosis can occur is B) DNA replication. DNA replication is a process of copying DNA into an identical copy. Before mitosis, the genetic material of the mother cell must duplicate so that each daughter cell have the same amount as the mother cell. On the other hand, meiosis is a reductive division. But meiosis II is similar to mitosis, so DNA replication is also necessary.</span>

A recessive allele does not affect the phenotype of a heterozygous person.
Effectus [21]

Answer: A. true

Explanation: The phenotype is the physical characteristics of a person. So, if a person has brown eyes, which may be a characteristic that is dominant, then they would have a genotype of BB or Bb. The reason why Bb, heterozygous, is not a different color is because the recessive b does not affect the dominant B allele.
