Question

Sickle cell disease in an inherited blood disorder. It is a recessive trait. That means you can carry one recessive allele for the disease and not have the symptoms. In this case, if you were a carrier and did not have the disease, your genotype for sickle cell would be...

Answer 1

B) Heterozygous

Step-by-step explanation:

You have a trait for sickle cell that cannot be expressed, this means a dominant allele is masking the sickle cell allele, thus meaning your gene is heterozygous since you will need to different alleles to have this trait.

Hope this Helps!

Answer 2

In this case, your genotype for sickle cell would be heterozygous. A recessive trait means that in order to have the disease (or phenotype of this trait) you need to have two copies of the gene that codes this trait. If you do not have the disease, then you do not have two copies of the gene for the sickle cell disease. Since you do not have the disease but you are a carrier, then you are heterozygous, meaning that you have one copy of the recessive gene and one of the dominant gene.
