First identify the gametes. use pink labels to identify the male and female gamete types and white labels to identify the gamete
Lady bird [3.3K]
I found the whole exercise on the internet. Attached is the scheme with labels for the gametes, f2 generation, and respective frequencies.

For the gametes position, on the left pink square on the male gametes side you should put a capital G, <span>and on the right pink square on the male gametes side you should put a small g, as</span> the only two possible offsprings that are showing is "GG" under the left male gamete and "gg" under the right male gamete. On the top pink square on the female gametes side you should put a capital G, and on the bottom pink square on the female gametes side you should put a small g, as the only two possible offsprings that are showing is "GG" on the same line as the top female gamete and "gg" on the same line as the bottom female gamete.
As for the frequencies of the gametes, you should put the white label that marks 1/2 by the side of each gamete.
Related to the F2 generation, the top right and bottom left pink squares should have the label with a capital G and small g - "Gg" which reflects the combination of the male gamete on its line with the female gamete also on its line.
As for the frequencies of the progeny, each of the genotypes formed from the union of the gametes should have by the side the white label that marks 1/4.
The totals would be that GG is 1/4, Gg is 1/2 (1/4+1/4), and gg is also 1/4.

The analysis of the nitrogenous bases of the nucleic acid of a newly discovered virus showed 20% adenine, 40% guanine, 10th% thy
Delvig [45]

Answer: The viral nucleic acid is most likely Deoxyribonucleic acid (DNA)

Explanation:

Unlike ribonucleic acid (RNA) where uracil can be found, thymine alongside adenine, cytosine and guanine are only found in DNA.

Thus, the presence of 10% thymine in the newly discovered virus makes its analyzed nucleic acid to be deoxyribonucleic acid (DNA)

Describe FOUR factors that may have an influence on the effectiveness of an antimicrobial treatment using various microbial cont
Vsevolod [243]
<span>These are:
1. <u>Number of microbes</u>: if there is a lot of microbes, then more time is needed to kill all of them.
2. <u>Characteristics of microbes</u>: some microbes have resistance genes, so they will not react to agents they are resistant to; some microbes have protective structures so treatment will be inhibited.
3. <u>Time of exposure</u>: different agents will need different time to kill microbes.
4. <u>Environment</u>: the effect of temperature, pH, organics both on microbes and agents.</span>

What evidence supports the common ancestory of humans and chimpanzees ?
I am Lyosha [343]
Autolapithecines are early hominid fossils promoted direc ancestral to humans. Primarily because autralopithecines had the head of chimpanzee but the body that allowed them to walk up right like humans. Their fingers, chest, hand bones, straining gain, shoulders, abdomen, inner ear canals developmental patters, toes and teeth ping point that they were human ancestors.
