Answer:
50% green-seed individuals vs. 50% yellow-seed individuals.
Explanation:
Mendel is known as father of genetics. He explained the concept of dominance, the law of segregation and the law of independent assortment while working on pea plant.
Green seed color is recessive and yellow seed color is dominant. A pure green line seed plant (ss) is crossed with heterozygous plant (Ss). The cross is as follows:
Parents ss (green seed) × Ss (Yellow seed)
Gametes s S, s
progeny: Ss, Ss, ss, ss.
Here, Ss is yellow seed and ss is green seed.
50% green-seed individuals vs. 50% yellow-seed individuals are formed after the cross.
Thus, the correct answer is option (a).

Explanation:
In sickle cell anemia, hemoglobin has the form of rigid bars inside the red blood cells, causing them to adopt sickle shapes being not very flexible. These cells can block blood vessels, stopping the flow, causing oxygen to not reach the tissues.
The cause of this anemia is due to a genetic mutation (there is a substitution of thymine for adenine in the beta globin gene, located on chromosome 11), generating Hemoglobin S with a decrease in oxygen binding.
