If a plant has the TtSs genotype, what would the genotypes of its gametes be? Tt, Ss, TS, and ts TT, tt, SS, and ss TS, Ts, tS,
ella [17]
<h2>Answer:</h2>
The correct option is last one, C, which is TS, Ts, tS, and ts.
<h3>Explanation:</h3>
- The genotype of plant is TtSs.
- There are two types of genes for one or two traits: T related trait and S related trait.
- T and S are dominant alleles while t and s are recessive alleles.
- Now the gamete contain one allele from one gene and other allele from other gene.
So the possible alleles are:

Vacuoles are storage organelles that are found in both animal and plant cells. They store food or any other forms of nutrients, they also store waste products so as to protect the contamination of the cell environment. These waste products are sent out of the cell via vacuoles. In plants the vacuoles are larger than in animals. The vacuole provides plant nourishment in the scarcity of water in the external environment hence, prevents the wilting of plants.
