On the planet Trogus, the population of Trogites have an autosomal gene, HDZ, with two alleles, T and t. T is dominant to t. Ind

ividuals with the T allele in their genotype show a propensity for sorbet, while the remainder prefer ice cream. In multiple population studies, 60% of individuals with the TT genotype prefer sorbet, 25% of Tt individuals prefer sorbet, and 5% of tt individuals prefer sorbet. In an F1 cross of Tt x Tt genotypes, among the F2 population of individuals who prefer ice cream, what is the probability that a random individual has the tt genotype

Answer:

The probability is 0.25 or 25%

Explanation:

To answer that question, you need to solve a Punnett Square. The Punnett Square allows you to observe the crossing of two parents, being able to observe the relationship between the alleles of each parent in the construction of the offspring. Punnett Square, is made on a table with eight squares. The alleles of one parent are placed in the first row, while the alleles of the other parent are placed in the first column. Therefore, each allele of one parent is combined with the allele of the other, as the remaining squares are filled. This combination of alleles leads to the genetic probability of a possible offspring.

In the case of the question above, the cross between the alleles of parents that both have the Tt (Tt x Tt) alleles is shown below, using the Punnett square.

          T        t

T        TT       Tt

t        Tt        tt

At this intersection, we can see that the "tt" alleles only appeared once in an offspring of 4 possibilities. Thus, we have a 1/4 calculation that is equal to 0.25, which represents a 25% probability that the offspring of this crossing will present individuals with the "tt" alleles.

Fofino [41]

Answer:

plant: This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).

The central vacuole takes up most of the volume of the cell. It is transparent, but you can see where it's pressing the chloroplasts up against the cell wall, especially at the ends of the cell.

Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane. The membrane is so thin and transparent that you can't see it, but it is pressed against the inside of the cell wall.

animal :This human cheek cell is a good example of a typical animal cell. It has a prominent nucleus and a flexible cell membrane which gives the cell its irregular, soft-looking shape.

Like most eukaryotic cells, this cell is very large compared to prokaryotic cells. For scale, notice the pair of dark blue bacteria cells sticking to the right edge of the cheek cell. The bacteria are only a fraction of the size of the nucleus, but their tiny size is typical for bacteria.

Fofino [41]
The Arctic Fox lives in the Arctic Tundra (more or less around Alaska, Iceland I think, and other places like that). During the winter, their fur is very thick and solid white (not always SOLID but generally speaking). During the summer and spring, their fur turns brown.

1. Of course, during the winter in those regions, it's going to be snowing and ice is going to be all over the ground. By having a white coat, they're able to blend in and hide from predators, such as the Arctic Wolf and Polar Bears. By turning brown, they'll be able to blend in with the dirt after the snow and ice melts, and again, hide from predators. For the other fox, their brown coat blends in with the dirt, trees, dead leaves, etc. and they'll be able to hide from prey and predators alike. 

2. The Arctic Fox also has very thick fur during the winter, which allows it to survive the extreme temperatures. They also dig burrows in the snow for shelter in blizzards. This gives them the ability to survive natural disasters (at least one of them).

I can't think of a third one but these should give you a pretty good idea of how their adaptations help them survive. I really love the Arctic fox so I know quite a bit about them. I really hope this helps you.

Molodets [167]

Answer:

The all possible gametic haplotypes that can be made are described below.

Explanation:

According to the question, F1 progeny was produced by crossing a homozygous dominant parent with a homozygous recessive parent. As per the question, cross is to be made with a heterozygous parent, which will have solid unpatterned allele and blue colour with a homozygous recessive i.e lined, aqua lizard.

The possible haploid gametes for the heterozygous parent would be BL, bl, Bl, bL and for homozygous parent would be all bl.
