[ANSWER INCLUDING]
The pedigree on the right shows the inheritance pattern for an X-linked recessive disorder.
The mother of the individuals circled in pink is not shown on the pedigree. Based on the phenotypes of these individuals and their father, what are the possible genotypes of their mother? Check all of the boxes that apply.
- XAXA
- XaXa
- XAXa

Answers

Answer 1

The mother's genotype can be either [tex]X^AX^A[/tex] or [tex]X^AX^a[/tex].

For X-linked recessive traits, males (XY) can either be affected or free from the disorder, they cannot be carriers. Females (XX), on the other hand, can be affected, unaffected, or be carriers.

The circled male child is free from the disorder ([tex]X^AY[/tex]) while the females are carriers ([tex]X^AX^a[/tex]).

The male inherited the healthy allele, [tex]X^A[/tex], from the mother.

The female children inherit the affected allele from their father (who is affected for the disorder) and the other healthy allele from their mother.

This means that the mother cannot be affected for the disease. As it is, the pedigree points that all the children got their healthy alleles from their mother. This does not mean the mother has two healthy alleles though.

Thus, the possible genotype of the mother are [tex]X^AX^A[/tex] and [tex]X^AX^a[/tex].

What is rock cycle ?

Rocks are naturally occurred on non-living earth which are made by collection of mineral grains held together in a firm, it can be tiny or big as well and can be easily identified with their texture.

The Rock cycle can be defined as a continuous process through which old rocks are transformed into new rock due to cool down of molten magma, when it solidifies become igneous rock.

In a rock cycle, when the break down of these igneous rocks occur small particles that are transported and deposited to form sedimentary rocks, When the igneous and sedimentary rocks heated up and under the pressure they change into metamorphic rocks.

The metamorphic rocks which are subjected under great heat and pressure melt down to form molten magma which again can cool down and solidify into igneous rocks

What stage of cell respiration is being shown above?

Answers

The stage of cell respiration that is being shown above is oxidative phosphorylation. During this stage, the transport of electrons is coupled to the generation of an electrochemical gradient.

Cellular respiration can be defined as a series of metabolic reactions by which aerobic cells generate energy in the form of ATP.

Cellular respiration has three main stages: glycolysis, the Krebs cycle and oxidative phosphorylation.

During oxidative phosphorylation, the transport of electrons across the mitochondrial membrane is coupled to the generation of an electrochemical gradient, which is then used to generate ATP by an ATP synthase as shown in the figure.

Answer: law of motion

Explanation:

Newton’s first two laws of motion explain how the motion of a single object changes. If the forces acting on the object are bal- anced, the object will remain at rest or stay in motion with con- stant velocity. If the forces are unbalanced, the object will accelerate in the direction of the net force. Newton’s second law tells how to calculate the acceleration, or change in motion, of an object if the net force acting on it is known.

Newton’s third law describes something else that happens when one object exerts a force on another object. Suppose you push on a wall. It may surprise you to learn that if you push on a wall, the wall also pushes on you. According to Newton’s third law of motion,

How is it possible to find the
number of heterozygotes in a
sample population, given the
allele frequencies?

Answers

Explanation:

The frequency of heterozygous individuals. Answer: The frequency of heterozygous individuals is equal to 2pq. In this case, 2pq equals 0.32, which means that the frequency of individuals heterozygous for this gene is equal to 32% (i.e. 2 (0.8)(0.2) = 0.32

To find the number of heterozygotes in a sample population, we need to know the allele frequencies and the total number of individuals in the population. The formula used to calculate the expected number of heterozygotes in a population is based on the Hardy-Weinberg equilibrium principle.

The Hardy-Weinberg equation is given as:

p² + 2pq + q² = 1

Where:

p = frequency of one (dominant) allele

q = frequency of the other allele (recessive) allele

p² = expected frequency of homozygous dominant individuals

2pq = expected frequency of heterozygous individuals

q² = expected frequency of homozygous recessive individuals

To find the number of heterozygotes, we can multiply the expected frequency of heterozygotes (2pq) by the total population size. This will give us an estimate of the number of individuals in the population who are heterozygous for the specific gene of interest.
