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.

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
