Answer 1

Answer:

The question lacks options, the options are:

a) varieties

b) phenotypes

c) genotypes

d) factors

e) alleles

The answer is B (phenotypes)

Explanation:

The phenotype of an organism refers to all observable traits it possesses. It refers to the physical characteristics of an organism as opposed to the content of its genes called genotype. Although, the traits an organism expresses is largely dependent on what is contained in its genome i.e. genotype determines phenotype.

Observable traits includes colour (yellow and green as mentioned in the question), height (tall or short), shape (round or wrinkled). An organism like plant will show or express a yellow colour (phenotype) when the yellow allele of the colour coding gene in its genetic makeup (genotype) is dominant.
