Answer:

Hello! DNA (Deoxyribonucleic Acid) is a molecule composed of two polynucleotide chains, which coil around each other to form a double helix that carries genetic instructions for the development, functioning, reproduction and growth of all known organisms and many viruses. DNA and the instructions contained in it passes from adult organisms to their offspring during the process of reproduction. Hope this helps ! :)

25. Review the graph below. Blue Jays and Robins do not interbreed. Assuming that both birds live in the same habitat, what woul

We do quite often have mutt birds. (the correct name for such a mutt is a hybrid. They are way more common than most people think, but unless you are a birdwatcher you probably wouldn’t even spot them. People often see an odd looking birds and simply think it’s a type they haven’t seen before, when in fact it is a hybrid of two well-known species.

Having said that, for birds to hybridized they have to be fairly closely related to start with. Robins and blue jays are no more closely related than humans are to baboons. You wouldn’t expect a human and a baboon to be able to mate and produce babies would you? So no, robins and blue jays can’t interbreed.

However there are many different species of animal that CAN interbreed and produce offspring. But the different species need to be fairly closely related, far more closely than human and baboon… or a blue jay and a robin.

For example we can interbreed horses and donkeys to produce baby mules, and we can breed cattle and buffalo, or camels and llamas. And the same is true of birds. While blue jays can’t be bred with robins in the wild we quite frequently find mutt birds.

 Ducks are particularly noted for forming wild mutts and many if not all north American mallards for example are of mixed species ancestry.

Why did Mendel want to control the pollination of his pea plants?

Viefleur [7K]

Mendel wants to control the pollination of his pea plants because traits were not blended but they remain separate in the subsequent generations and also it is contrary to scientific opinion during his time

Explanation:

Mainly, he wants to control because they were against the scientific opinion during his time.
Mendel takes a pea plant for his experiment because it can be easily observable.
Pea plant has seven traits and it can be pollinated by both the ways. One is self-pollination and the other is cross-pollination.
Mendel did not know about the genes but he speculates the factors of formation in the traits.
Mendel produces three laws, the law of dominance, the law of segregation, the law of independent assortment.
