Which number shows the highest heritability?

A high heritability, close to 1, indicates that genetics explain a lot of the variation in a trait between different people; a low heritability, near zero, indicates that most of the variation is not genetic.

What is the difference between a person’s genotype and phenotype?

A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics. For example, having blue eyes (an autosomal recessive trait) is a phenotype; lacking the gene for brown eyes is a genotype.

Can you change your genotype?

Genotype generally remains constant from one environment to another, although occasional spontaneous mutations may occur which cause it to change. However, when the same genotype is subjected to different environments, it can produce a wide range of phenotypes.

Can as genotype marry AA?

Can sickle cell be cured?

Does sickle cell lower life expectancy?

People who have sickle cell disease have a reduced life expectancy. Some people with the disease can remain without symptoms for years, while others do not survive beyond infancy or early childhood. New treatments for SCD are improving life expectancy and quality of life.

What gender is most affected by sickle cell anemia?
