The sickle cell version of the gene that causes sickle cell disease is recessive. Suppose that two parents with no symptoms have

Answer:

The genes that the child inherited from the parents is the SS gene

Explanation:

The genetic composition of the haemoglobin genotype is given by two gene variants; A which is dominant and S which is recessive. As such, an individual can be AA, AS or SS. Individuals that are AA and AS do not show traits of the disease, but SS individuals have sickle cell anaemia.

From this example, since both parents have no symptoms and their child have sickle cell, their genotypes most likely were AS and AS. Let me show you how:

           A              S

A        AA            AS

S       AS              SS

From the cross above, there is a 1 in 4 chance that if both parents were AS, their child will be SS. Any other composition from the parents will not produce an SS offspring. Hence the genes that the child inherited from the parents is the SS gene.

how can scientists accurately compare atmospheric composition today with atmospheric composition thousands of years ago?
Vinil7 [7]

Answer:

They accurately compare the current atmosphere with the previous one, by assessing the amount of atmospheric gases present today, with the amount of atmospheric gases trapped in ice cores that they believe are millennial, that is, they have existed for thousands of years ago.

Explanation:

As we know, it is difficult to compare current characteristics of the planet earth with characteristics that the planet had in the past, thousands of years ago. This is because the ancient characteristics on earth are not fully available to be analyzed, since most of them have been modified over time.

To do this, scientists need to find factors that may have existed thousands of years ago and assess whether these factors have any account of the characteristics of the earth. In the case of atmospheric characteristics, it is common for scientists to compare the current atmosphere with the atmosphere of thousands of years ago, with the assessment of the amount of atmospheric gases trapped in ancient ice cores, with the amount of atmospheric gases present in the atmosphere today.
