Alleles are alternative form of gene and are present at same place on chromosome
suppose the two alleles S and T are controlling leaf colour so the genotype that will b possible is SS.ST.TT and for species B the 6 phenotypes will occur so i conclude that
<span>Species B will have a wider range of phenotypes
</span>so D is correct
hope it helps

A
Explanation:
Reptiles arose about 310–320 million years ago during the Carboniferous period.
Answer: Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself. In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
The great majority of the cell divisions that happen in your body involve mitosis. During development and growth, mitosis populates an organism’s body with cells, and throughout an organism’s life, it replaces old, worn-out cells with new ones. For single-celled eukaryotes like yeast, mitotic divisions are actually a form of reproduction, adding new individuals to the population.
In all of these cases, the “goal” of mitosis is to make sure that each daughter cell gets a perfect, full set of chromosomes. Cells with too few or too many chromosomes usually don’t function well: they may not survive, or they may even cause cancer. So, when cells undergo mitosis, they don’t just divide their DNA at random and toss it into piles for the two daughter cells. Instead, they split up their duplicated chromosomes in a carefully organized series of steps.
Answer:
A monohybrid cross is defined as the cross happening in the F1 generation offspring of parents differing in one trait only.
Explanation:
A dihybrid cross is a cross happens F1 generation offspring of differing in two traits.
