What is the height of the f1 plant if the tall plant AABBCC is crossed with a base height plant aabbcc?
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)
What did mendel perform when he crossed plants that were heterozygous for two traits?
When Mendel crossed a true-breeding short plant with a true-breeding tall plant, all the offspring were tall. Which term describes the gene for tallness?
If two heterozygous plants create four offspring how many do you predict would be tall?
1 will be hemozygous tall TT(25%), 2 will be heterygous tall Tt(50%), and 1 will be dwarf tt.........tatal, 75% will be tall
What must be true for a cross between a tall plant and a short plant to produce any short plants?
the tall plant must be heterozygous.
How could the f1 generation of tall offspring produce 3 tall plants and 1 short?
An F1 x F1 cross would be a cross between heterozygous (Tt) parents. The offspring would be 1/4 TT, 1/2 Tt, and 1/4 tt. This would mean that 3/4 of the offspring would be tall, and 1/4 would be short.These offspring would be the F2 generation.

When model crossed true-breeding tall plants with true-breeding short plants all of the offspring were tall because?
Homozygous for tall is TT Homozygous for short is tt All F1 offspring from this cross are Tt which makes them genotypically heterozygous and phenotypically tall.
You perform a test cross on a tall pea plant half the offspring are short what conclusion can you draw from this outcome?
The genotype of the tall pea plant is heterozygous
What letters can be used to model Mendels cross of true-breeding tall plants what true-breeding short plants in a Punnett square?
TT for the homozygous tall parent, tt for the homozygous short parent and Tt for the heterozygous offspring.

5 An F1 plant that is homozygous for shortness is crossed with a heterozygous F1 plant What is the probability that a seed from the cross will produce a tall plant?
there is a 50% chance that the offspring will be tall.

What generation is always completely heterozygous?
The F1 (first filial) generation is always 100% heterozygous.This is because the F1 generation is defined as the offspring of pure-breeding (homozygous) parents carrying different alleles from each other, e.g. AA x aa. All the offspring must be Aa, in other words heterozygous.
What must br true for a cross between a tall plant and a short plant to produce any short plants?
The tall plant must be heterozygous.
