sometime in the not-too-distant future, a catastrophic event ends the world as we know it, leaving only one population of 20,000 humans in north america. we sample a neutrally evolving locus with only two alleles, and find that the a1a1 genotype occurs in 7200 people. what is the expected number of people that are heterozygous at this allele, assuming hardy-weinberg equilibrium? group of answer choices 3,200 7,200 9,600 12,000 12,800

Answers

Answer 1

According to hardy-weinberg equilibrium, 12,000 persons should be heterozygous for this gene.

How are the anticipated heterozygotes determined?

In relation to allele frequency, p, expected heterozygosity (Hexp = 2pq) for a 2-allele system is shown. The heterozygosity reaches its apex at a value of 0.5 when the allele frequencies are equal (p=q). At both ends, it is negligible because everyone is a homozygote of one type or the other.

How is heterozygous calculated by Hardy-Weinberg?

The proportion of heterozygous people is equivalent to 2pq. In this instance, 2pq is 0.32, which indicates that 32% of people are heterozygous for this gene (2 (0.8)(0.2) = 0.32).

if there is 8 g of a substance before a physical change, how much will there be afferwards

Answers

Answer:

The correct answer is 8 g.

Explanation:

During a physical change, the identity of the substance does not change, because no chemical reaction occurs. So, after the change, the amount of substance is still the same. Examples of physical changes are changes in the state of matter (solid-liquid-gas). If 8 grams of ice (water in the solid-state) are melted, after the melting process we will have 8 grams of water in the liquid-state, but still 8 grams of water.

WHAT IS The 2nd phase of mitosis

Answers

Answer:

When prophase is complete, the cell enters prometaphase — the second stage of mitosis. During prometaphase, phosphorylation of nuclear lamins by M-CDK causes the nuclear membrane to break down into numerous small vesicles. As a result, the spindle microtubules now have direct access to the genetic material of the cell.

At Weeks Bay there was a population of 200 alligators. In May of 2006 a new species of catfish was released into the Mississippi.

The following summer of 2007, 100 babies were born and a total of 40 gators died that year. However, the next year in early 2008 there was a terrible drought, causing 100 alligators to die.

After a month of heavy rain, a formerly clear pond on a golf course is covered with slimy green algae. What do you think happened?

Answers

Pond water most definitely gets cloudy after a good rain, most of this cloudy water caused by dust, pollen, dirt, debris, and other materials getting washed into the pond and as this material floats and circulates in the pond it gives a cloudy look to the pond, and typically it is just a matter of a day or so for the pond water to be filtered clear again. After your pond water has filtered clean, it is a good time to clean your pond filter too, as all those materials need now to be removed from your pond filtration system.

However, sometimes pond green water conditions can occur. The green water condition in the pond occurs because of the sudden introduction of nitrate and nutrient rich water into your pond; the nutrient levels spike, the planktonic algae in your pond has a sudden huge food (nutrient) supply available, so it can now reproduce like mad increasing in numbers exponentially and wah-lah! You’ve got green water, and green water is simply that….large numbers of floating planktonic algae that now are so densely populated that their green coloration from chlorophyll makes your water appear green.

What are prokaryotic cells?

A cell type without a genuine nucleus or membrane-bound organelles is referred to as prokaryotic. All the other types of life are eukaryotic, whereas organisms in the categories of Bacteria and Archaea are centered on the prokaryotic cell.

Prokaryotic species, on the other hand, are exceedingly prevalent and account for a large portion of the biomass on Earth.

Unicellular organisms are those that have prokaryotic cells. We refer to them as "prokaryotes." A prokaryotic cell may operate as a live creature thanks to a number of factors. Prokaryotes have a cell membrane covering them at first.

With the help of this membrane, they may engineer a particular environment for metabolic processes within the cytosol. Second, these cells contain both ribosomes and free DNA.

Even though ribosomes are organelles, a plasma membrane does not enclose them.

Therefore the correct option is A.
