If the cells of the morula or the inner cell mass split, what type of twins will develop?Multiple choice question.FraternalDoubleConjoinedIdentical

If two eggs are fertilized by two separate sperm, what type of twins will develop?Multiple choice question.ConjoinedIdenticalFraternalPaternal

Fraternal twins also known as monozygotic happens when two eggs have been released by the mother and then fertilized by two sperm.Select one:a.FALSEb.TRUE

The inner cell mass will eventually become the Blank______.Multiple choice question.blastocystfetusmorulazygote

Which forms two new cells from a single cell?

You are studying the development of a poorly-understood marine species. Watching an embryo develop, you see asymmetric cleavage and what appear to be protein granules apportioning to a few of the cells. Your labmate suggests pinching the embryos in half, so you have twice as many animals for your next experiment. Do you follow his advice?Multiple ChoiceNo -- this would result in twins, but they would be smaller and less healthy.No -- this would result in deformed embryos, since this species does not appear to have regulative development.Yes -- separating the blastomeres should result in two identical twins.Maybe -- it would depend whether the egg has large amounts of yolk to support two embryos.
