Answer #1

The correct answer is (a) No, it is evident from the information that the student will have genotype IAi as the mother has genotype ii.

- we know that, blood group in humans is due to three alleles - IA, IB and i. Here, IA and IB are co-dominant to each other a

Parent C gamete> ii (mothor) ) IA JA | IA i father (IA) [Produce 1 gamete ] r father may x affpoing> IA i (A Type) So, this i

    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...
