Solution
-
The term 'phenotype' refers to an individual's physical appearance for a particular characteristic. It is the observable traits or characteristics of an organism as a result of the interaction of its genotype and the environment.
-
A 'dominant allele' is a gene that is always expressed even if it is only present on one of the chromosomes. It is the version of a gene that will produce a certain phenotype, even in the presence of other alleles.
-
The genotype of a homozygous dominant pea plant is TT. This means that the plant has two copies of the dominant tall allele.
-
A pea plant with a heterozygous genotype for height, where the tall allele is dominant, would be expected to be tall. This is because the presence of the dominant tall allele (T) will mask the effect of the recessive short allele (t).
-
The genotype of a boy is XY. This is because males have one X chromosome and one Y chromosome.

By observing it, you can see that it has a tall stem as well as many other different traits.Using this example, explain the difference between phenotype and genotype. Which one can be observed? Which one helps to determine the other?
