Answer:
The correct option is D
Explanation:
Beta-thalassemia major is a hereditary disorder that usually causes severe anaemia. This mutation/disorder eventually leads to death if untreated especially during in the first two years of infancy. The treatment usually involves the transfusion of blood to clear the phenotypic blockage caused by the mutation. However, it requires both alleles to have the thalessemia mutation for a patient to be said to have beta-thalassemia major. Hence, <u>it is </u><u>not true</u><u> that it involves just the x allele and thus affects males more often than females</u>.
I believe the answer would be A, because if water didn’t exist, there would be no presence of living things on earth. Water is a resource for life, thus, presence of living things.
Glucose and Oxygen are the reactants
Answer:
As she is heterozygous, her genotype would be Aa. The eggs she produce would have one allele from her genotype, and thus she can produce A or a eggs.
