makkiz [27]3 years ago

Answer:

Presence of two copies of mutated alleles would cause sickle cell anemia in person.

Explanation:

The gene HBB codes for the beta globin protein of hemoglobin. Hemoglobin is the protein present in red blood cells and serve in oxygen transport. Mutation in HBB gene leads to production of abnormal hemoglobin molecules. These hemoglobin molecules stick to each other and impart stiffness and sickle shape to the red blood cells. Presence of two copies of mutated gene leads to sickle cell anemia characterized by reduced oxygen supply to the body cells and/or blocked blood vessels.

In humans, there are four blood types: A, B, AB and O. Each parent can give their offspring one of three blood type alleles, IA
Delvig [45]

Answer: One parent is IAi and the other parent is IBi

Explanation: As this trait is codominant, the child can inherited IA, IB or i.

Tina has type O, which means she is ii and her sister is AB, so her genotype is IAIB. Now, to have a child with a recessive trait both parents has to carry at least one allele for the recessive, i. Rosa is type AB which means she had to have inherited one allele IA from one of her parents and the other IB from the other parent. Thus, one parent is IAi and the other is IBi.
