28) Before Mendel's experiments with pea plants, which ideas formed the basis for most thinking about heredity? A. Species gradually change over time B. The traits of both parents are blended together in their offspring C. Heredity occurs within species D. Some traits are dominant and some are recessive

Step 1
Mendel's work revolutionized the understanding of heredity by introducing the concepts of dominant and recessive traits and the particulate inheritance of genes. Therefore, options that reflect Mendel's findings (like option D) would not have been the prevailing Show more…

Which of the following conclusions was a result of Gregor Mendel's observations? A: Organisms that give rise to purebreds are genetically superior B: Organisms that have intermediate features are self-pollinating C: Organisms inherit two copies of each gene, one from each parent D: Organisms that self-pollinate do not have "either-or" features

Which of the following observations led Mendel to conclude that some traits were recessive? A. Plants with a certain form of each trait were more likely to survive and reproduce than plants with other forms of each trait. B. The offspring produced during his first set of experiments expressed one form of a trait, while the offspring produced during his second set of experiments expressed a different form of the trait. C. When he crossed plants that expressed different forms of a trait, one form always "disappeared" and never "reappeared in later generations. D. The form of a trait that seemed to "disappear" during his first set of experiments "reappeared" during his second set of experiments.

"Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. He recognized the mathematical patterns of inheritance from one generation to the next." Through his work, Mendel published his experiments to explain his findings. What did his laws of inheritance state? SELECT ALL THAT APPLY A.Parental genes are randomly separated from the sex cells so that sex cells contain only one gene of the pair. B.Each trait of an organism can contain multiple alleles of that trait. C.Organisms with alternate forms of a gene will express the dominant form of the gene. D.The inheritance of one trait is not dependent on the inheritance of another. E.Genes can be transferred from the parent generation directly to the offspring based on the environmental factors surrounding the offspring.
