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?

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

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?
