A researcher observes a 1:2:1 phenotypic ratio in the F2 generation of a plant cross. Which inheritance pattern is most consistent with this result? (a) Complete dominance (b) Codominance (c) Incomplete dominance (d) Polygenic inheritance 37. If the blood group of both the parents is AB, then the possible blood group of their children will be: (a) A, B and O (b) AB and O (c) A, B, AB and O (d) A, B and AB 38. In a plant species, flower color is determined by a single gene with incomplete dominance. Red (RR) and white (rr) produce pink (Rr). If two pink- flowered plants are crossed, and 180 offspring are produced, how many are expected to be pink? (a) 45 (b) 60 (c) 90 (d) 120 39. Which of the following statement is true? (A). Mendel published "Experiments on Plant Hybridization" in the year 1866 (B). Specific gene position on a chromosome is allele (C). Law of Segregation states that each organism carries two alleles for a trait, and these alleles separate during gamete formation (D). One of the reason for choosing pea plant by Mendel was ease of cross-pollination (a) A, B & D (b) B, D & C (c) A, B, C & D (d) A, C & D 40.
