Almost positive that it's option C, because ultraviolet rays indeed do that, i'm not good with the study of x-rays but i'm sure it doesn't go with #3.

In gorillas, the ability to roll the tongue is under the control of 1 gene. The R allele, which confers tongue-rolling ability,

aalyn [17]

Answer:

0.4550

Explanation:

In this example, R allele is dominant, so individuals RR and Rr can roll their tongues. If in a population of 1000 gorillas, there are 575 gorillas who can roll their tongues, they will be RR and Rr.

In this case, there is Hardy Weinberg Equilibrium, so the following will be true:

$p^{2}+2pq+q^{2}=1$

Where:

$p^{2}=$ frequency of RR

$2pq=$ frequency of Rr

$q^{2}=$ frequency of rr

The question is what is the frequency of heterozygotes, or, what is the value of 2pq.

We know that RR+Rr is 575 individuals in a population of 1000, or 0.575.

In other words:

$p^{2}+2pq=0.575$

So, it is possible to find $q^{2}$ :

$q^{2}= 1-2pq-p^{2} \\q^{2}=1-(0.575)\\q^{2}=0.425$

Now, there are two alleles in the population, so the following will be true:

$p+q=1$

It is possible to find q (the frequency of allele r) and p (the frequency of allele p):

$q=\sqrt{q^{2} }\\ q=\sqrt{0.425} \\q=0.652$

Therefore:

$p=1-q\\p=1-0.652\\p=0.348$

Now, the frequency of heterozygotes or 2pq is:

$2pq=2*0.652*0.348\\2pq=0.45$

Select the correct statement about plant life cycles.

vagabundo [1.1K]

The right answer is A.

Meiosis is an important process in many organisms:

In angiosperms, plants with flowers, meiosis occurs for the production of cells of pollen grains (gametes, haploid cells).

In animals, meiosis is important because it is the mechanism of gametogenesis that produces eggs (oogenesis) and sperm (spermatogenesis).

In the fungi, meiosis produces spores, which by mitosis will give a haploid generation.
