Which of the following best describes mendel's idea of segregation? a. each parent may pass on one or two factors for each trait to its offspring. b. male offspring receive chromosomes only from the male parent. c. female offspring receive chromosomes only from the male parent. d. each parent passes on only one factor for each trait to its offspring.

The correct option will be option D (Each parent passes on only one factor for each trait to its offspring).

Explanation:

Gregor mendel worked on the pea plants and discovered the "fundamental laws of inheritance".

The law of Segregation states that inherited trait occur in two genetic alleles copies which randomly separates during gamete formation with each gamete receives only one genetic allele which reunite during fertilization. Therefore, offspring inherit one genetic allele from each parent. For example:

         Parents :                              Yy         X        Gg

                                                      ↓                        ↓

        Offsprings :                 Y   ←    →   y         G  ←   → g

Thus, option D is the correct answer.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

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.
