Practice question
Question
Mendel deduced the genetic principle of inheritance by experimenting on sweet pea plants. One of the experiments involved crossing plants with two contrasting characters, tall (dominant) and dwarf (recessive), which yielded all tall plants in the first generation. When the same genetic cross was independently repeated by a researcher, only short plants were obtained. Which one of the following can possibly explain the altered outcome?
Explanation
Mendelian segregation analysis shows allele distribution and recombination generate phenotypic variation. Consequently A suppressor for the tall allele is present in the dwarf plant emerges as the valid choice since it follows segregation and linkage principles, aligning with established principles in genetics literature.
