Answer:

Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells

A gene (gene X) undergoes a mutation which converts if from wild-type to mutant. Then a second mutation in the gene Y occurs whi
Tcecarenko [31]

Answer:

b. forward mutation, suppressor mutation

Explanation:

When the nucleotide sequence of an organism is altered, it is called as mutation. It can be caused by DNA damage or replication errors. In forward mutation, the wild type allele is converted to a mutant version such that the gene product is non functional or its not produced at all. Suppressor mutation is the second mutation which reverses the phenotypic effects of the previous mutation. This process is called as synthetic rescue.

Since here gene X was converted into a mutant form by the mutation, it had undergone forward mutation. When gene Y was mutated, the function of gene X was  restored which ultimately also restored the phenotype hence it is an example of suppressor mutation.
