course hero which of the following is not an example of pre-zygotic isolation?

What are the 5 examples of Prezygotic isolation?

It looks like there are five major types of prezygotic barriers to reproduction: spatial isolation, temporal isolation, mechanical isolation, gametic isolation and behavioral isolation.

What are the 4 types of Prezygotic isolation?

Forms of prezygotic isolation include spatial, behavioral, mechanical and temporal isolation. Postzygotic isolation occurs after members of two different species have mated and produced a zygote.

Which of the following is not an example of pre zygotic isolation?

Correct Answer: C) Hybrid sterility is correct answer because it is a not type of pre zygotic isolating mechanism, but it is a type of post-zygotic...

Which of the following is an example of pre zygotic isolation?

Habitat isolation, behavioral isolation, temporal isolation, mechanical isolation and gametic isolation are all examples of prezygotic isolating mechanisms.

What is a pre zygotic isolation mechanism?

Pre-zygotic isolation. Pre-zygotic isolation mechanisms are the most economic in terms of the natural selection of a population, as resources are not wasted on the production of a descendant that is weak, non-viable or sterile. These mechanisms include physiological or systemic barriers to fertilization.

Which situation is not an example of a Prezygotic barrier?

Answer and Explanation: d. Two species of insects produce infertile offspring is not an example of a prezygotic barrier.

Which of the following is an example of a post-zygotic reproductive barrier?

Explanation: Hybrid sterility is an example of post-zygotic reproductive isolation.

Which of the following is an example of zygote mortality?

Explanation: Zygote mortality is an example of post-zygotic reproductive isolation. In this type of reproductive isolation, gametes from two species may fuse, however the zygote is inviable shortly after fertilization due to improper development.

What is an example of postzygotic isolation?

What is an example of postzygotic isolation? One example of postzygotic isolation is zygote mortality. This is where the zygote cannot develop properly and dies. This is generally the case for hybrid offspring between goats and sheep.

What are the 3 examples of Prezygotic barriers mentioned?

Prezygotic barriers: Anything that prevents mating and fertilization is a prezygotic mechanism. Habitat isolation behavioral isolation temporal isolation mechanical isolation and gametic isolation are all examples of prezygotic isolating mechanisms.

What are Prezygotic barriers quizlet?

prezygotic barrier; when different species reproduce at different times. habitat isolation. prezygotic barrier; the species remain isolated because they breed in different habitats. behavioral isolation.

Which is a Prezygotic isolating mechanism quizlet?

A prezygotic reproductive isolating mechanism in which species live in the same habitat but breed at different times of day or different times of year. A prezygotic reproductive isolating mechanism in which two species do not mate because of differences in courtship behavior; also known as ethological isolation.

What is polyploidy in biology?

Polyploidy is a common mechanism of sympatric speciation in
