charle [14.2K]

Answer:

The correct answer is - autosomal codominant inheritance (due to multiple alleles).

Explanation:

Autosomal codominant inheritance or codominance is a pattern of inheritance where the alleles present of an autosomal gene express their character in the phenotype. In other words, in this type of pattern, no allele would be masked by other alleles and both will be expressed in the phenotype.

The human ABO blood group is an example of this pattern as there are three alleles A, B, and O. In the heterozygous case of AB blood group both A, and B alleles expressed together however, O is masked by both alleles A, and O.

If two people with sickle cell trait have children, what is thechance that a child will have normal RBCs in both high-and low-ox
Vanyuwa [196]

Answer:

See the answer below

Explanation:

<em>The chance that a child from two people with sickle cell trait will have normal RBCs remains the same irrespective of the amount of oxygen in the environment.</em> From the cross:

                  AS    x    AS

            AA    AS    AS    SS

Hence, the chance of having a child with normal RBCs in both high and low-oxygen environments is 1/4 or 25%.

The chance that a child will have sickle cell disease is also 1/4   or 25%.
