Question

In a Mendelian cross of Standard dominance, All of the F1 individuals are _____________________ for the trait being studied.

Answer 1

Answer:

In a Mendelian Standard dominance crossing, all F1 individuals are dominant for the trait under study.

Explanation:

In his experiments, Mendel used 34 varieties of pea Pisum sativum. The plant was chosen on the recommendation of other biologists because it has large flowers and easily identifiable features such as pea color and texture, pod color, flower color and plant height. In addition, Pisum sativum is a self-fertilizing plant. And their offspring are always identical to the original plant - unless artificially or cross-fertilized.

In one of his experiments, Mendel crossed two purebred plants, one with yellow seeds and one with green seeds. The monk then verified that all descendants were identical to one of the parents. In this case, the phenotypic trait of one of the parents was not expressed: all descendants of the first generation had yellow seeds. Mendel called the feature that appeared in the F1 generation dominant and the recessive feature that did not express itself as recessive.
