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. Instead it had been by the “heritable factor” of the trait (purple flowers).

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).

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
