How Hot Weather Effects Plants. Hot, dry summers are rough on plants, especially on non-native plants and those weak from improper care. Since many of our landscape plants aren't naturally adapted to heat, they need special attention and care.
Blood groups are inherited from both parents. The ABO blood type is controlled by a single gene (the ABO gene) with three types of alleles inferred from classical genetics: i, IA, and IB.The gene encodes a glycosyltransferase âthat is, an enzyme that modifies the carbohydrate content of the red blood cell antigens.lood groups are inherited from both parents. The ABO blood type is controlled by a single gene (the ABO gene) with three types of alleles inferred from classical genetics: i, IA, and IB.
A person with alleles A and B for blood type has type AB blood. The alleles are codominant -- neither one alone determines the blood type.lood type AB, A and B are codominant, and therefore both are expressed in the individual. Blood type is determined by their possession or lack of the antigens A and B, which â¦ are carried on the surface of the red cells. Persons may thus have type A, type B, type O, or type AB blood.
