MrRa [10]

I assume the question asks for the number of phenotypes present.

The phenotype is the set of visible characteristics of an individual resulting from the interaction of its genotype. In this case, the number of phenotype is the total number of combinations of the characteristic purple or white and wrinkled or smooth:

<span>purple and smooth
white and smooth
purple and wrinkled

How can a zygote receive an abnormal chromosome number?
noname [10]

Explanation:

Some chromosomal conditions are caused by changes in the number of chromosomes. These changes are not inherited, but occur as random events during the formation of reproductive cells (eggs and sperm). An error in cell division called nondisjunction results in reproductive cells with an abnormal number of chromosomes

Chromosome abnormalities often happen due to one or more of these: Errors during dividing of sex cells (meiosis) Errors during dividing of other cells (mitosis) Exposure to substances that cause birth defects (teratogens)
