In radishes, color and shape are each controlled by a single locus with two incompletely dominant alleles. Color may be red (RR), purple (Rr), or white (rr) and shape can be long (LL), oval (Ll), or round (ll). What phenotypic classes and proportions would you expect among the offspring of a cross between two plants heterozygous at both loci?

1/16 red long

1/8 red oval

1/16 red round

1/8 purple long

1/4 purple oval

1/8 purple round

1/16 white long

1/8 white oval

1/16 white round

Explanation:

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
