None of the above, A hybrid zone between two species of butterflies contains individuals with widely varying genotypes, ranging from those matching both parental species to those with varying proportions of genes from the parental species. c. It requires different mutations occurring in each of the two populations. The operation of natural selection So, if two different species mate, the sperm may be unable to recognize the egg. an inherited or learned trait that increases an organism's chance of survival in its environment. Genetic drift For example, surface proteins on the eggs of one species prevent sperm of the wrong species from entering. Thus, these species are considered _______ species. Mechanical isolation is when the reproductive parts of one individual are not compatible with the reproductive parts of another individual. Estimate (a) the roughness ratio of the pipe and (b) the percentage change in head loss if the pipe were smooth and the flow rate the same. The term 'hybrid' can also mean the cross between different varieties within a species but for this lesson, we'll use it to mean a cross between two separate species.
