As parent's genotypes are missing here, alleles cannot be estimated in offspring, but it is possible to use the example above to estimate it.

<h3>What is a Punnett square?</h3>

A Punnett square is a diagram used in genetics to estimate genotypic and phenotypic frequencies in offspring from a given genetic cross.

In order to estimate offspring allele frequencies, we need to know parental genotypes by means of a Punnett square.

For example, if both parents are heterozygous for a gene whose alleles are called 'A' and 'a', the Punnett square in offspring is:

        A         a

A     AA      Aa

a     Aa       aa

In this case, 50% of offspring will be heterozygous (genotype 1/2 Aa), whereas 25% will be homo-zygous dominant (1/4 AA) and 25% will be homo-zygous recessive (1/4 aa).

In conclusion, as parent's genotypes are missing here, thereby alleles cannot be estimated in offspring, but you can use the example above to estimate it.

Can you explain how more life-forms were able to create because of cyanobacteria​ PLEASE HELP
Ainat [17]

The cyanobacteria changed the composition of the earth’s atmosphere by evolving oxygen in what is referred to as the Great Oxygenation Event. This also allowed the ozone to be formed and block off most of the UV rays that are destructive to genetic material. Life was, therefore, also able to exist on land other than in water.

Kenny has a sore throat and visits the doctor. The nurse collects a throat swab, places the swab on a petri dish, and then place
Doss [256]
The answer is C: because growth at 37°C would be ideal for revealing bacteria that are human pathogens. 37°C is equivalent to 98.6°F, the normal body temperature for humans. If bacteria are reproducing at this temperature in a petri dish, they are also most likely reproducing in the body. 

Cultures are made so doctors can be sure a person is sick with a specific bacteria often in order to make sure they are taking the right medication to get better. Choice A doesn't make sense, because we wouldn't want to kill the bacteria we are trying to study. Bacteria that makes us sick is harmful bacteria and is what we are trying to isolate. Choice B doesn't make sense, because they are only being incubated at one temperature, not a range or variety. Choice D is harder to rule out, but again the doctor wants the bacteria to reproduce so they can be sure that's what is causing the infection, so it wouldn't make sense that we would put the bacteria in a temperature they would not reproduce.
