Question

______ Organisms in the same "species" would be very similar in their genetic makeup.

Answer 1

Species is the basic unit of biological classification, here the number is too large, and in nature they can produce a fertile offspring. Organisms in the same species are similar both in their external appearance and their internal physiology; More the relationship is closer between two organism, the more there will be similarity between them.

On the other hand the genetic makeup of a cell is the genotype, specific genetic characters/traits (DNA sequence) present, which in turn determines the specific characteristic (phenotype) of that individual.

From the same organism class and genus, species might look very similar. As the species are from the same organism, so they have the range of genes or traits among them, that's why they are similar too. Genetic makeup determines the look.

The mating between the organisms in the same species brings the traits in one place, and the share of traits among the offspring’s, both external and internal characteristics which develop from their DNA. Sharing of the traits, if produces to be more common the more closely they look like. Just like people and their families, depending on their DNA similarity.

For example, a child is more similar in look with his father, this is the genes that determining the outward expression, thus the statement species would be very similar in their genetic makeup proves to be true.
