Answer:

It does. - True.

Explanation:

The changes in species change species themselves, which creates diversity. If evolution didn't happen, diversity would be null - only one species of each animal. One type of beetle, one type of cow, one type of bee, one type of ant, one type of spider. If these animals never change, they either go extinct for lack of adaptation or they just remain like that, and diversity isn't affected.

But, if animals do change, then the opposite occurs, new species start originating in different parts of the world, increasing local and worldwide biodiversity.

In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aa plants have yellow ke

lara31 [8.8K]

Answer:

Explanation:

As given,

Allele A for blue anthocynin.

aa for yellow kernel;

at second locus;

W produce smooth kernel,

ww for wrinkled kernel;

Parents as given are: AaWw and aaww

Progeny are:

blue smooth ( AaWw)= 1447;

blue wrinkle (Aaww)= 169;

yellow smooth (aaWw)= 186;

yellow wirnked (aaww)= 1510

Recombinant progeny are 169+ 186= 355

non- recombinant progeny are = 1447+ 1510= 2957

so recombination frequency (RF)= 346/2957×100= 12.0054%

So a and w are linked genes.

They are 12 mu far away from each other.

b) Blue smooth parent= AaWw.

c) Aaww crossed with aaWw

progeny are= AaWw, Aaww, aaWw, aaww,

They all are produced in same proportion =0.25% or 1/4.

5 Sperm fertilizes the egg

1 Pollen is released from the anther

4 The pollen tube reaches the ovule within the ovary

2 Pollen sticks to the stigma

Explanation:

The process of double fertilization entails the fertilization of the egg by one sperm and that of two polar nuclei to produce the triploid endosperm tissue that nourishes embryo.
