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.
2.There are four major blood groups, and they are also subject to the Rh factor, so in reality there are 8 human blood types. The types are A+, A-, B+, B-, AB+, AB-, O+ and O-. Blood types are inherited by the person inheriting one allele for a given blood group from one parent and another from the other parent.
