Question 19
XL-RNAT2 marksNeeds review
Plant weight is determined by a pair of alleles at each of the two independently assorting loci (A and Bb) that are additive and equal in their effects. The recessive alleles do not contribute towards plant weight. Plants with genotype aa bb are 1 g in weight, whereas plants with genotype AA BB weigh 3.4 g. Plant with genotype aa bb is crossed with a plant of genotype AA BB. The weight (in g, round off to one decimal place) of an individual plant in F₁ progeny of this cross would be
