Is a statement based on repeated experiment observations that describe some aspect of the universe
"The Sperm's Long Journey. A man may ejaculate 40 million to 150 million sperm, which start swimming upstream toward the fallopian tubes on their mission to fertilize an egg. Fast-swimming sperm can reach the egg in a half an hour, while others may take days. The sperm can live up to 48-72 hours."
Reproductive isolation is the separation of species populations on the basis of behavior, geography or time. According to the given information statement ii, i.e., one population breeds in late spring and one in late summer and statement iv, i.e., singing by male of first population than other ones shows evidence that two populations are likely experiencing reproductive isolation and genetic exchange.
<h3>What is genetic exchange?</h3>
New genotype of species are formed through the process of genetic exchange.
Reproductive isolation for example, is in changes of bird song from different species of finch. Females of one species of finch are unable to recognize the bird song of males. This is a barrier that is pre-zygotic.
Another includes one population breeds in late spring and one in late summer and singing by male of first population than other.
Thus, the correct statements are ii and iv so the correct option will be D.
