This approach enabled him to determine that variations among offspring were the result ofrandom mutations.self-pollination.genetic uniformity.his crossings.48100cc_profilecc.multiple_choice.v0p1When Mendel crossed plants that were purebred purple-flowered with plants that were purebred white-flowered, the resulting offspring all had purple flowers. When allowed to self-pollinate, this F generation gave rise to white-flowered plants as well as purple. As a result, Mendel determined that individual traits areinherited as discrete units.diluted in offspring.merged with successive generations.lost in the pollination process.49100cc_profilecc.multiple_choice.v0p1Mendel was able to identify predictable patterns of heredity. He succeeded mainly because he chose to study traits thatwere always dominant.tended to be recessive.could be diluted.had only two forms.56100cc_profilecc.multiple_choice.v0p1Which of the following conclusions was a result of Mendel's observations?Organisms that give rise to purebreds are genetically superior.Organisms that have intermediate features are self-pollinating.Organisms inherit two copies of each gene, one from each parent.Organisms that self-pollinate do not have "either-or" features.59100cc_profilecc.multiple_choice.v0p1<p>Which phrase best describes the process of crossing over?</p>Pairs of homologous chromosomes exchange segmentsParis of sister chromatids exchange segmentsPairs of homologous chromosomes become linkedPairs of sister chromatids become linked61100cc_profilecc.multiple_choice.v0p1<p>During what stage of meiosis does crossing over occure?</p>prophase I of meiosis Ianaphase II of miosis IItelophase I of meiosis Imetaphase II of meiosis II65100
