the results Mendel obtained during his experiments. It showed that if you cross two plants that were true-breeding for different colors (purple and white), the offspring or first generation (F1) would be ______________ instead of true-breeds, and all were _____________ in color. Interestingly, when he crossed two of these F1 plants, their offspring did not all come out _____________. Instead he obtain a ratio of ______ purple-flowered plant for every ______ white-flowered plant. He concluded that the “heritable factor” for the ____________ trait (white flowers) was not destroyed in the F1 generation.

Explanation:

As illustrated in this question, Gregor Mendel used the color trait of pea plant to discover his law of dominance.

The results Mendel obtained during his experiments. It showed that if you cross two plants that were true breeding for different colors (purple and white), the offspring or first generation (F1) would be HETEROZYGOUS (Pp) instead of true-breeds, and all were PURPLE in color.

Interestingly, when he crossed two of these F1 plants (Pp × Pp), their offspring did not all come out PURPLE, instead he obtain a ratio of 3 purple-flowered plant for every 1 white-flowered plant. He concluded that the “heritable factor” for the RECESSIVE trait (white flowers) was not destroyed in the F1 generation. Instead it had been MASKED by the “heritable factor” of the DOMINANT trait (purple flowers).
