    Background for Discussion: Blood type is determined by the "alleles" that are inherited from the parents Alleles are possible types of a particular gene, in this case the blood type gene. There are four main blood types A, B, AB, or O; and three basic type alleles A, B, and O. Children have two alleles, one inherited from each parent. Blood types A and B are called co-dominant alleles, while type O represents the absence of a factor and is...

    In this scenario, the mother has blood type A and is heterozygous (IAi). The father has blood type B and is also heterozygous (IBi). First, please complete the Punnett square below. Add one allele into each parental allele box, and a complete genotype (such as IAIB, IBi or ii) into each offspring box. Remember that dominant alleles should always be written before recessive alleles in a genotype (IBi, never iIB). Please review my powerpoint! BLOOD TYPE (A and B alleles...
