Assume that plant weight is determined by a pair of alleles at each of two independently assorting loci (A and a, B and b) that are additive in their effects. Further assume that each allele represented by an uppercase letter contributes 4 g to weight and that each allele represented by a lowercase letter contributes 1 g to weight. If a plant with genotype AA BB is crossed with a plant with genotype aa bb, what weights are expected in the F, progeny? a.1g
b. 4g
c. 8g
d. 10g
e. 16g

10g

Explanation:

A cross between genotype AA BB is crossed with a plant with genotype aa bb will produce

Parent genotype:AABB x aabb

Gametes: AB x ab

F1 generation - AaBb

Since an uppercase letter contributes 4 g to weight and each allele represented by a lowercase letter contributes 1 g to weight.

Thus, 4+1 + 4 + 1 = 10g

uh two lol

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
