Which graph represents selection that may lead to reduced variation in a population? A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The original population and population after selection have similar curves, but the original population peaks before the population after selection. A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The population after selection increases, decreases, increases, and then decreases again. The original population increases at the point that the original population drops. A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The original population peaks at the same time as the population after selection but the population after selection peaks higher and at a more rapid speed. A graph has trait value on the horizontal axis and proportion of individuals on the vertical axis. The original population and population after selection have similar curves but the original population is slightly higher at all points. Mark this and return

How does the DNA sequence in a normal hemoglobin gene compare to a sickle cell hemoglobin gene?



ASAP

Answers

Answer:A person with normal hemoglobin has inherited one allele for normal hemoglobin from each parent and so has the genotype Hb A/Hb A. In contrast, a person who has sickle disease has inherited one sickle-cell allele from each parent and has the genotype Hb S/Hb S.

Explanation:

The DNA sequence in a normal hemoglobin gene is different from the hemoglobin gene of sickle cell due to a change in nucleotide base from A to T.

What is Sickle cell anemia?

Sickle cell anemia is a group of disorders which cause the red blood cells (RBCs) to become misshapen and break down. It is an inherited group of disorders, in which the red blood cells contort into a sickle shaped cell. The cells die early due to this disorder, leaving a shortage of healthy red blood cells in the blood and can block the blood flow causing pain and crisis.

Symptoms of sickle cell anemia include infections, pain and fatigue.

Genetic studies have shown that the base sequence in the normal hemoglobin (HbA) and the sickle cell hemoglobin (HbS) differs at only a single nucleotide position including a change from an A to a T nucleotide base. This change in nucleotide to one codon results in a single amino acid change in the hemoglobin.
