The two forms interbreed and their offspring survive and reproduce well.
Explanation:
When talking about classification of species, one of the first features observed is the species fitness, which describes the reproductive success or their ability to leave to their successive generations the most copies of their genotype. When different species that were recently divided into 2, by geographic isolation, for instance, usually there is no genetic compatibility, and if its possible to produce offspring, there might be some development issues like infertility.

c. The cells of all organisms contain DNA that is housed in a membrane-bound nucleus.
Explanation:
DNA is the genetic material found in the cells of living organisms. Among the characteristics of the DNA that makes up the genetic code, it is said to be nearly universal though. DNA is said to be the "blueprint of life".
This means that the DNA sequence that encodes protein and useful information is the same in almost all living organisms. Hence, the statement that "cells of all organisms contain DNA that is housed in a membrane-bound nucleus is the" justification that fact that all organisms share some basic features and life processes is used by biologists to explain the idea that all life.
