the following data were obtained from a lebanese population. blood type percent of individuals o 36% a 13% b 45% ab 6% a. calculate the frequencies of the ia, ib and io alleles. assume that the population is in hardy-weinberg equilibrium. b. in this population, a couple with type b blood plan to have a child. what is the probability that they will have a son with type o blood?

Answers

Answer 1

a. To calculate the frequencies of the IA, IB, and I alleles, we can use the following formulas:

p + q + r = 1

p2 + 2pq + q2 = 1

where the frequencies of the IA, IB, and I alleles are represented by p, q, and r, respectively.

Given the level of people with each blood classification, we can switch them over completely to frequencies by partitioning by 100:

p(O) = 0.36

p(A) = 0.13

p(B) = 0.45

p(AB) = 0.06

The complement of the sum of the IA and IB alleles can be used to determine the frequency of the I allele:

r = 1 - p - q

r = 1 - 0.13 - 0.45

r = 0.42

The equation for heterozygotes can be used to determine the frequency of the IA and IB alleles:

2pq = p(A) * p(B) * 2

p + q = 1 - r

p + q = 1 - 0.42

p + q = 0.58

2pq = 0.58 * 0.45 * 2

2pq = 0.522

p = sqrt(2pq - q2)

p = sqrt(2 * 0.522 - 0.452)

p = 0.174

q = sqrt(2pq - p2)

q = sqrt(2 * 0.522 - 0.172)

q = 0.398

Therefore, the frequencies of the IA, IB, and I alleles in this population are:

p(IA) = 0.174

p(IB) = 0.398

p(i) = 0.428

b. The genotype IBi is shared by the couple with type B blood. We must take into account the potential genotypes of their offspring as well as the corresponding blood types in order to determine the probability of having a son with type O blood.

The Punnett square for this cross would look like this:

| IB | i

--|-----|-----

IB| IBB | iB

i | iB | ii

Each crate addresses a potential genotype of their posterity, and the letters address the alleles acquired from each parent. The primary box (IBB) addresses a kid with genotype IBIB and blood classification B, the subsequent box (iB) addresses a kid with genotype IBi and blood classification B, the third box (iB) addresses a kid with genotype IBi and blood classification B, and the fourth box (ii) addresses a youngster with genotype ii and blood classification O.

The likelihood of having a kid with type O blood is equivalent to the recurrence of the ii genotypes:

P(ii) = p(i) * p(i)

P(ii) = 0.428 * 0.428

P(ii) = 0.183

Subsequently, the likelihood that the couple will have a child with type O blood is roughly 0.183, or 18.3%.

In living things, cells must be in a _____________________ solution where water leaves and enters the cell at _________________________________________.

Answers

Answer:

isotonic; the same rate

Explanation:

Cell Theory as as commonly known gives the best definition for cells. All organisms that ever existed are made up of one or more cells. The theory state that the cell is a basic unit, that is of all living things, and that all cells come from cells that have existed.

For cell that is in an isotonic solution,no net flow of water into or out of the cell will be experienced, the volume of the cell is at a state of stability. When the level or concentration of solute in and out of the cell is at the same pace or level, the the cell membrane does not allow solutes to cross, leading to the solution being isotonic to the cell.

If a cell has 40% solute and is placed in a solution with 60% water what will happen to the cell

Answers

There will be no net movement of water in or out of the cell.

Water moves out of the cell when a cell is placed in a hypertonic solution. This is a solution that contains more solute than does the cell. When a cell is placed in a hypotonic solution, water enters into the cell from the solution until the cell finally bursts. However, if the cell and the solution contain the same amount of solute, there is no net movement in or out of the cell.

We can see here that the cell has 40% solute and is placed inside a solution that has 60% water. This means that the solution also contains 40% solute. There will be no net movement of water in or out of the cell.

You catch, tag, and release 35 fish back into a pond. Then, you catch 70 more fish, 12 of which have tags on them. What is the best estimate of the number of fish in the pond?

Answers

Answer:

204

Explanation:

The estimated total number of individuals in a population using the capture and recapture method is given by the following equation;

N = (M x C)/R

where N = estimates of the number of individuals in the population, M = number of individuals captured and marked the first time, C = total number of individuals captured (marked and unmarked) in the second attempt, and R = number of marked individuals captured in the second attempt.

In this case, M = 35, C = 70, and R = 12

Hence,

N = 35 x 70/12 = 204.16

Therefore, the estimated number of fish in the pond is 204.

Answers

Answer:

Marble D

Explanation:

According to this question, a group of four students is participating in a marble race. Each marble is said to have different mass but the same force were applied to each of them.

The relationship between the mass, force and acceleration of an object has been explained with the equation: F (force) = mass (m) × acceleration (a).

F = ma

Hence, a = F/m

Based on this, with a constant force, the acceleration is inversely proportional to the mass of an object. This means that when the mass increases, the acceleration decreases and vice versa. Based on the table showing the value for mass and uniform force for each marble, the marble with the highest mass (90) will have the least acceleration (0.66666). This marble is MARBLE D.

Which small-scale mutation would be most likely to have the least negative effect on the function of a protein?

A base deletion near the start of a gene
A base deletion near the end of the coding sequence, but not in the terminator codon
A deletion of three bases near the start of the coding sequence, but not in the initiator codon

Answers

Answer:

substitution

Explanation:

has a chance to cause silent mutation, which doesnt do anything to a protein.

The small-scale mutation that would most likely have the least negative effect on the function of a protein is ; ( A ) A substitution of one base for another within the sequence.

A substitution of one base for another within the sequence of a protein will cause an insignificant/silent mutation within the protein sequence and this mutation will not be evident in the protein.

When a base is deleted either near the start of a gene or near the end of the coding sequence, it will have a significant effect because this will change the sequence of the DNA ( due to the deletion of at least one nucleotide ).

Hence we can conclude that the small-scale mutation that would most likely have the least negative effect on the function of a protein is ; A substitution of one base for another within the sequence.
