The possible genotypes of the offspring of the parents are RR, Rr, and rr.

<h3>What are dominant traits?</h3>

Dominant traits are characters which are always present in every generation.

A dominant trait is encoded for by the dominant allele of a gene.

Assuming the genotype of the parents are Rr and Rr.

The cross between them will give:

Rr × Rr = RR, Rr, Rr and rr.

Therefore, the possible genotypes of the offspring of the parents are RR, Rr, and rr.

vlabodo [156]

Answer:

need to be done with plenty of observation to avoid infection.

Another risk is that by passing the time, there is a difficult in respiratory, in this case, the main risk is directly to the heart, with some stoke, due to the high concentration of carbon dioxide due to the low exchange among oxygen and CO2.

Some of the indications are:

a.- Coarse crackles auscultated over trachea.

b.- Increase the respiratory pressure.

c.- Decrease tidal volume.

d.- Check the levels of oxygen in blood as in arteries.

e.- Check that patients can generate a cough.

Nitella [24]

Answer:

The correct answer will be options-

1. they share genetic similarities

2. they can interbreed

3. they fall under the same genus

Explanation:

The taxonomic studies help the organism to identify, nomenclature and classification of the organism.

The classification system helps organize the organisms into several groups based on the similarity of the morphological characters. The species is the lowest group of the system which contains the organism which is reproductively isolated from the other group of organism.

If two organism is found to be of the same species shows that they share the same gene pool, belongs to the same genus and they can interbreed.

Thus, the selected options are the correct answer.
