Question

Many populations of clams release their sperm and eggs into the same region of a lake, but only the sperm and eggs from the same species successfully unite to form zygotes.

True / False.

Answer 1

True.

Step-by-step explanation:

Zygote is formed by the fusion of the male and female gamete. The sperms and ova can be released in the water or any other environment depending on the type of species.

The clams also releases their gametes in the water. The sperms and eggs that belong to the same species can successfully unites to form the zygotes. This also represents the gametic isolation.

Thus, the correct answer is false.
