WORD BANK multiple alleles three Punnett square alleles genotype incomplete dominance Fo. recessive in genetics is an inheritance pattern where two alleles blend to create a 2. phenotype. All our traits are coded by our genes, and humans have two copies of each gene, one from the maternal parent and one from the paternal parent. These copies are called alleles. MN ABO two A B 25 į 으 50 or the observable trait of the is use, where each of the 4 boxes of offspring is Mendel implied that only two alleles, one 6. and one could exist for a given gene. Although individual humans (and all diploid organisms) can only have two alleles for a given gene, 8. may exist at the population level, such that many combinations of two alleles are observed. An example of multiple alleles is the 9. blood type system in humans. In this case, there are three alleles circulating in the population. The 10. the 11. allele codes for A molecules on the red blood cells. allele codes for B molecules on the surface of red blood cells, and the 12. allele codes for no molecules on the red blood cells. In this case, the A and B alleles are 13. with each other and are both 14. over the i allele. Although there are three alleles present in a population, each individual only gets 15. of the alleles from their parents.​
