A locus that affects susceptibility to a degenerative brain disease has two alleles, V and v. In a population, 16 people have ge

Pie

Answer:

Yes, the population is evolving

Explanation:

Hardy-Weinberg equilibrium states that a population is not evolving if it is in hardy weinberg equilibrium as the alleles frequency do not change over time in generations.

In mathematical equation, the genotype frequency will be -P²+2Pq+q²=1 and allele frequency will be p+q=1, where p = dominant allele and q will be recessive allele.

In the question, since the observed genotype are-

P² - VV= 16

2Pq- Vv- 92

q²- vv- 12

<u>1. Calculate allele frequency</u>

Now we will calculate if the expected value is same or close or not.

We will calculate allele frequency

Population has 120 individuals which means it has - 240 alleles.

In which V (p) will be- 32 +92= 124 allele

p- dominant allele/ total allele= 124/ 240 = 0.52

P= 0.52

q will be 1-0.52= 0.48

<u>2. Expected genotype frequency</u>

Now we will calculate expected genotypic frequency.

P²- 0.52 X 0.52= 0.27

2Pq = 2 x 0.52x 0.48 = 0.5

q²= 0.48 x 0.48 = 0.23

<u>3. Expected progeny </u>

P²= 0.27 x 120= 32 VV

2Pq= 0.5 X 120= 60 Vv

q²= 0.23 x 120= 28 vv

Since the observed value is not equal to the expected value therefore the population is not in Hardy- Weinberg equilibrium and the population is evolving.

Thus, Yes, the population is evolving is correct.

Which will most likely cause a decrease in the predator population? an increase in prey populations 2. a decrease in prey popula

e-lub [12.9K]

Answer:

$\huge\boxed{\sf A \ decrease \ in \ prey\ population}$

Explanation:

Predators are those animals which hunt prey. Prey is the animals which is "hunted".

When the prey population is less (a decrease in prey population), There will not be more animals for "predators" to hunt and so, the competition of living will become more. Decrease in preys population would lead to a decrease in predator's population because many predators will die of hunger.

Hope this helped!
