Answer:

EeWw

Explanation:

This question involves two genes; one coding for earlobes and the other for hairline. According to the question, one parent is homzygous recessive for earlobe but homzygous dominant for hairline i.e. (eeWW) while the other parent is homzygous dominant for unattached earlobes but homzygous recessive for hairline i.e. (EEww).

The cross between the two parents is as follows: eeWW × EEww. The following gamete combination will be produced by each parent:

eeWW - eW, eW, eW, eW

EEww - Ew, Ew, Ew, Ew

Using these gametes in a punnet square, the following proportions of offsprings will likely be produced:

All EeWw offsprings

Which describes the greenhouse effect? an artificial process a dangerous process a natural process a new process

Yuri [45]

The answer would be a dangerous process, this is because the greenhouse effect traps gasses such as CO2 and other harmful gasses emitted from the Earth, that can ultimately lead to problems in the future.

The greenhouse effect is also the reasoning behind why scientist believes in Global warming and climate change.

Plus, the greenhouse effect is neither natural, new, nor artificial.

Where does oxygen move from the respiratory system to the circulatory

Vedmedyk [2.9K]

Answer: Alveoli

Explanation: Alveoli of lungs are surrounded by extensive blood capillaries. The partial pressure of oxygen in the alveoli is higher than the blood entering the pulmonary capillaries, hence oxygen moves into the blood. Carbon dioxide in the lungs simultaneously diffuse out of the blood into the alveolar space.

I WILL GIVE BRAINLIEST!!!

Nesterboy [21]

Answer:

25%

Explanation:

When looking at a pedigree remember that:

squares are males
circles are females
the solid colored figure represents an individual affected by a disease
the empty figure represents a healthy individual

Let us assign the symbol X⁺ to represent the dominant allele linked to the X-chromosome and expressing healthiness, and X⁻ to represent the recessive allele expressing the dissease.

According to this pedigree

I1 is a man affected by the disease, YX⁻
I2 is a healthy woman X⁺X⁻
we can see that among the progeny (generation II) there are two individuals affected (a boy and a girl) and one healthy girl. This means that the mother I2 is heterozygous for the trait.

So, having their genotypes we can know what are the probabilities of getting a son with DMD

Parentals) YX⁻ x X⁺X⁻

Gametes) Y X⁻ X⁺ X⁻

X⁺ X⁻

X⁻ X⁺X⁻ X⁻X⁻
