The major blood group locus in humans produces types A (genotypes AA or AO), B (genotypes BB or BO), AB (genotype AB), or O (genotype OO). Parents who are type AB and type O, what are the possible blood types of their offspring?

#Section 3: Genetics, Cellular and Molecular Biology
In the pearl-millet plant, color is determined by three alleles at a single locus: Rp1 (red), Rp2 (purple), and rp (green). Red is dominant over purple and green, and purple is dominant over green (Rp1 > Rp2 > rp). What will be expected phenotypes and ratios of offspring produced by the Rp1/rp × Rp2/rp crosses?

#Section 3: Genetics, Cellular and Molecular Biology
In a maternity ward, four babies become accidentally mixed up. The ABO types of the three babies are known to be A, B, and AB. The ABO types of the four sets of parents that are clamed are determined.
(A) AB X O (B) A X O, (C) A X AB, (D) B X O.
Following some statement is given
A. A blood group baby must be child of Parent B
B. B blood group baby must be child of Parent A
C. AB blood group baby must be child of Parent A
D. AB blood group baby must be child of Parent C
Which of the following above statement is correct?

In the pearl millet plant, color is determined by three alleles at a single locus: Rp1 (red), Rp2 (purple), and Rp3 (green). Red is dominant over purple and green, and purple is dominant over green (Rp1 >Rp2 >Rp3). Which of the following parental cross would produce ½ had red, ¼ purple, ¼ green?
