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.
Rr, R is the dominant gene) In blood type, A is dominant over O. So if a persoâ¦n has Ao for their genes, they will have A type blood. A recessive gene will be hidden unless there are two of the same recessive gene. It is shown as a lowercase letter in the gene (i.e. Rr, r is the recessive gene). In blood type, O is the recessive allele, so you cannot have O type blood unless you have 2 O alleles: oo.
