In such a cross, the F1 plants will always be tall, because that is the dominant allele. In the cross described, a homozygous dominant plant was crossed with a homozygous recessive plant; a cross that produces 100% heterozygous offspring. (AaBbCc)

Is a plant with the genotype AABbcc heterozygous for two different genes?

No, because it has the AA and the CC those are homozygous. The Bb is the only heterozygous trait, and there is only 1.

Is the height of a plant independent or dependent?

the height of a plant is independent because you never have an exact estimate for everything.


What did mendel conclude after his stem height pea plant experiment?

Mendel's experiment showed that with other traits it showed a similar pattern and also that it resulted that this crossed the first generation. The dwarf height traits had seemed to disappear. He then let the first generation plants self pollinate.

A true breeding tall plant was crossed with a true breeding short plant If alleles did not segregate during gamete formation?

All offspring would be heterozygous for the gene controlling plant height. This is because if alleles do not segregate, they remain together and are passed on as a unit. The offspring plants would all be tall because the allele for tallness is dominant over the allele for shortness.
