Human ABO blood type is determined by a single gene that comes in 3 distinct alleles: IA , IB , and i. The IA and IB alleles are
each dominant to the i allele, but are codominant with each other, meaning that both phenotypes are expressed in the heterozygote. The Punnett square below shows a cross between two parents with different blood types.Drag the genotypes and phenotypes from the left to correctly complete the Punnett square.
The earth-sun-moon system affects a lot of things on earth, some of which are agriculture, tides, seasons, temperature, weather/climate, living things, ect.
