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.
The A and B alleles are dominant to the O allele. When both inherited alleles are O, the genotpye is homozygous recessive and the blood type is O. When one of the inherited alleles is A and the other is B, the genotype is heterozygous and the blood type is AB.AB blood type is an example of co-dominance since both traits are expressed equally.1  Type A: The genotype is either AA or AO. 2  Type B: The genotype is either BB or BO. 3  Type AB: The genotype is AB. 4  Type O: The genotype is OO.B blood type is an example of co-dominance since both traits are expressed equally. 1  Type A: The genotype is either AA or AO. 2  The antigens on the blood cell are A and the antibodies in the blood plasma are B. 3  Type B: The genotype is either BB or BO.
