Which of the following statements correctly describes how Mendel accounted for the observation that traits had disappeared in th

e F1 generation and then reappeared in the F2 generation?
A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.
B) New mutations were frequently generated in the F2 progeny, causing traits that had been lost in the F1 to reappear in the F2.
C) Members of the F1 generation had only one allele for each trait, but members of the F2 had two alleles for each trait.
D) The mechanism controlling the appearance of traits was different between the F1 and the F2 plants.

Answer:

A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.

Explanation:

Mendel discovered the fundamental theory of heredity: that inheritance involves the passing of genes (he called it discrete units of inheritance), from parents to offspring. Those genes are with two alleles in the genotype, one inherited from the father and other inherited from the mother.

When he cross-bred pure-bred parent (always produced offspring identical to the parent) plants dominant traits were always seen in the offspring, while recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Mendel also noticed that in second-generation (F2) of the offspring 3:1 was ratio of dominant to recessive traits.

Vaselesa [24]

Answer:

A scientific law is simply an observation of the phenomenon that the theory attempts to explain. For example, suppose that you were lying under an apple tree and observed an apple fall from a branch to the ground. The observation of this phenomena can be called the law of gravity.
