Considering the same population of cats as in Part A, what is the expected frequency of each genotype (TLTL, TLTS, TSTS ) based

zaharov [31]

Answer:

P = f(TLTL) = 0,16

H = f(TLTS) = 0,48

Q = f(TSTS) = 0,36

Explanation:

Hello!

The allele proportion of any locus defines the genetic constitution of a population. Its sum is 1 and its values can vary between 0 (absent allele) and 1 (fixed allele).

The calculation of allelic frequencies of a population is made taking into account that homozygotes have two identical alleles and heterozygotes have two different alleles.

In this case, let's say:

f(TL) = p

f(TS) = q

p + q = 1

Considering the genotypes TLTL, TLTS, TSTS, and the allele frequencies:

TL= 0,4

TS= 0,6

Genotypic frequency is the relative proportion of genotypes in a population for the locus in question, that is, the number of times the genotype appears in a population.

P = f(TLTL)

H = f(TLTS)

Q = f(TSTS)

Also P + H + Q = 1

And using the equation for Hardy-Weinberg equilibrium, the genotypic frequencies of equilibrium are given by the development of the binomial:

$p^{2} = f(TLTL)$

$2pq = f(TSTL)$

$q^{2} = f(TSTS)$

So, if the population is in balance:

$P = p^{2}$

$H = 2pq$

$Q = q^{2}$

Replacing the given values of allele frecuencies in each equiation you can calculate the expected frequency of each genotype for the next generation as:

$f(TLTL) = P = p^{2} = 0,4^{2} = 0,16$

$f(TLTS) = H = 2pq = 2*0,4*0,6 = 0,48$

$f(TSTS) = Q = q^{2} = 0,6^{2} = 0,36$

I hope you have a SUPER day!

Two species of birds feed on mistletoe berries. The birds are active at different times of the day and do not come into contact

I am Lyosha [343]

Answer:

The correct answer is B. exploitation

Explanation:

Exploitation competition occurs when the interaction of two species is indirect when they complete for the same resource like food, place, etc. The use of resources by one individual species reduces the amount of resources for the other species leading to competition.

So over time the more fit species will out complete the less fit species. So here two species of bird feed on the same food but at different times and so they reduce resources for each other which is an example of exploitation competition.

Which way does earth rotate—from east to west, or west to east? Explain your answer.

77julia77 [94]

The earth rotates from West to East or if you want another way of saying it, counter-clockwise. It rotates from West to the East because the earth's Western Hemisphere (West) rotates to the Eastern Hemisphere, (East).

P.S. I hope this helps you!!
