Question

​When Mendel crossed true breeding tall and short parent plants (producing first generation), what was produced? a. ​All the offspring were tall. b. ​Half the offspring were tall, the other half were short. c. ​About 90 percent were tall, but the rest were short. d. ​All the offspring were short. e. ​The offspring were intermediate in height relative to the two parent plants.

Answer 1

A. All the offspring were tall.

Step-by-step explanation:

The tall gene was dominant over the short gene, and therefore the offspring's genotype would be Tt (T representing the dominant tall gene, t representing the recessive short gene). This means the phenotype (visible trait) would be tall.
