If the yellow allele is dominant (Y) and the green allele is recessive (y), what are the possible genotypes of a green offspring?

Answer:

yy

Explanation:

it can only be yy because you need 2 recessive genes to show a recessive trait.

A plant with Yy genes could pass the recessive genes on, but would still show the dominant trait.

The possible genotype of the green offspring is yy, i.e., recessive one and will express only in absence of dominant allele.

In a broad sense, the word "genotype" refers to an organism's genetic makeup; in other words, it describes an organism's entire set of genes.

In a narrower sense, the term can refer to the alleles, or variant forms of a gene, that an organism carries.

A genotype is a classification of the type of variant found at a specific location (i.e., a locus) in the genome.

Symbols can be used to represent it. For example, the letters BB, Bb, bb could be used to represent a specific variant in a gene.

In the given scenario, Y is dominant allele which will express in combination with y means the recessive one.

Thus, for expressing the green allele, it should be yy.
