Answer:
b) spontaneous reverse mutation
Explanation:
Spontaneous mutations are produced by natural biological processes, while induced mutations are produced by mutagenic agents that trigger nucleotide errors in the DNA sequence. In the first phase of the experiment, Sally generated an induced mutation by using 5-bromouracil. The resulting strain required a constant supply of tryptophan to grow.
A reverse mutation restores the wild-type phenotype modified by a forward mutation, thereby reversing the phenotypic alteration to its original state. In a second step of the experiment, the colonies grew without the supply of tryptophan, thereby evidencing that the mutation was reversed in the original colony.
<span>The daughter producing sperm used to fertilize Brittany's eggs should be haploid sperm cells. These cells contain one set of chromosomes. The work haploid also refers to the amount of chromosomes in sperm or an egg cell, sometimes called gametes. In human beings, gametes are generally haploid cells that have 23 chromosomes which each has one chromosome pair that can be found in diplod cells.</span>
