If matings are not random in a population and individuals mate with other individuals of similar genotype/phenotype, h0m0zyg0us frequencies increase. In this example, the genotype frequency for Mm is F(Mm) = 0.25.
---------------------------------
In the exposed example, one of the assumptions of Hardy-Weinberg equilibrium is not accomplished. There are non random matings.
Individuals mate with other snails of the same genotypes
MM x MM
Mm x Mm
mm x mm
We can assume this is an example of matings by similar phenotypes.
Eventually, this mating system leads to an increase in the h0m0zyg0us genotype frequency, at the expense of heter0zyg0us ones in loci that determine the trait.
Allelic frequencies do not change. Only genotypic frequencies do.
This mating system tends to separate the population into two subgroups, decreasing the amount of heter0zyg0us individuals.
Matings Progeny
MM x MM 4/4 MMMM x Mm 1/4 MM + 2/4 Mm + 1/4 mmmm x mm 4/4 mmZygotic population of the next generation
F(MM) = 4/4 MM + 1/4 MmF(Mm) = 1/2 MmF(mm) = 4/4 mm + 1/4 MmSo, in the exposed example we know that the frequency of the dominant allele M is 0.5
f(M) = p = 0.5
knowing that p + q = 1, we can clear the equation to get the frequency of the recessive allele.
p + q = 1
0.5 + q = 1
q = 1 - 0.5
q = 0.5
f(m) = q = 0.5
Zygotic population of the next generation
F(MM) = 4/4 MM + 1/4 MmF(MM) = p² + 1/4 (2pq)
F (MM) = 0.5² + 1/4 (2 x 0.5 x 0.5) = 0.25 + 0.125
F(MM) = 0.375
F(Mm) = 1/2 MmF(Mm) = 1/2 (2pq)
F(Mm) = 1/2 (0.5)
F (Mm) = 0.25
F(mm) = 4/4 mm + 1/4 MmF(mm) = q² + 1/4 (2pq)
F(mm) = 0.5² + 1/4 (2 x 0.5 x 0.5) = 0.25 + 0.125
F(mm) = 0.375
The expected genotype frequency for Mm individuals in this population is F(Mm) = 0.25.

Which adaptation is common to animals that live in temperate grasslands?
structures to dig burrows
keen eyesight to help them see in the evening
a thick insulating layer of fat
large ears to regulate body temperature
Answer:
This is 100% right.
Explanation:
Temperate grasslands are characterized by vast expanses of open grasslands with few trees and shrubs, so structures to dig burrows are a common adaptation for animals that live in temperate grasslands, as is preset in the first option.
What are temperate grasslands?Temperate grasslands are biomes characterized by vast expanses of open grasslands with few trees or shrubs. These ecosystems experience a wide range of temperature fluctuations between seasons, with hot summers and cold winters. As a result, animals that live in temperate grasslands have evolved adaptations that enable them to survive in this challenging environment. One of the most common adaptations of grassland animals is the ability to dig burrows. Burrows provide shelter and protection from predators, as well as a stable microclimate for animals to live in.
Hence, structures to dig burrows are a common adaptation for animals that live in temperate grasslands, as is present in the first option.

A. ozone depletion
B. global warming
C. acid rain
D. air pollution
The burning of fossil fuels does not contribute to ozone layer depletion.
The burning of fossil fuels leads to the release of gases such as oxides of nitrogen, sulfur, and carbon as well as particulate matter such as smoke, ashes, etc.
The oxides released from fossil fuel burning can cause global warming (carbon dioxide), acid rain (SO2), and air pollution (particulate matter).

Draw the structure of ATP molecule and explain how it is formed
ATP is formed from the breakdown of glucose molecule in mitochondria of the cell.
ATP molecule is formed in the process of respiration i.e. aerobic and anaerobic. During aerobic cellular respiration, glucose reacts with oxygen in the mitochondria of the cell, forming ATP that can be used by the cell in different cellular activities. When glucose reacts with oxygen, three molecules are formed i.e. ATP, Carbon dioxide and water. ATP is used by the cell whereas the Water and carbon dioxide molecules are waste materials which are removed from the cell so we can say ATP is formed from the breakdown of glucose molecule in mitochondria of the cell.Learn more about ATP here: https://brainly.com/question/893601

HELP QUICKLY Why are the deepest high tides so deep and the shallowest low tides so shallow? Hint: how are the Earth, Sun, and Moon aligned?
There are different kinds of tides. This change occur because when the gravitational pull of the sun works along with the gravitational pull of the moon on Earth, it leads to the oceans bulging out.
This result above makes the high tides as been little higher and low tides been little lower than normal.Spring tides are known to be the deepest as oceans levels are highest in this kind of tide. The neap tides are known to be the shallowest.
This often occurs when the moon, earth, and sun are said to be at a right-angled plane. Therefore, the gravitation pull of the moon and sun on the oceans do counteract each other making its net effect is smaller.

Answer:: De-termination could offer experiences into development and normal assets that are at present inaccessible to us.
2: Compromised or harmed biological systems could be reestablished with the assistance of specific now-wiped out species.
3 In the event that people drove plant and creatures species into termination, maybe we owe it to these species to attempt to bring them back.
4 De-elimination could be a major advance forward for hereditary designing.
There are loads of valid justifications to bring back wiped out creatures. All creatures perform significant jobs in the environments they live in, so when lost species are returned, so too are the 'positions' they once performed. Wooly mammoths, for instance, were nursery workers. ... It very well may be something similar for other de-wiped out creatures, as well.
Zeroing in on de-elimination could think twice about by redirecting assets from protecting environments and forestalling more current eradications. It could likewise diminish the ethical load of annihilation and backing for imperiled species, sending the mixed signal that resuscitating a wiped out creature or plant is trifling
im not sure if im right or if this is even close but i hope this helps of it doesn't i am so sorry
