What is the process that reduces the amount of genetic material in gametes by one-half?
Meiosis
Who was the first scientist to successfully refute the idea of acquired physical characteristics being passed on to offspring?
Weissmann
What process did Weissmann call reduction division, which is now known as?
Meiosis
Which type of plant breeding involves breeding plants with the same genetic traits for many generations?
Purebred breeding
In Mendel's experiments, what did he observe when he cut off the tails of several generations of mice?
Their offspring were born tailless
What is the term used to describe the process by which cells divide to produce genetically identical cells?
Mitosis
What did Mendel theorize about characteristics or traits?
They come in pairs, one from each parent, with dominance of one trait over the other.
What did Mendel's experiments focus on to document results accurately?
Plant height, pea pod color, seed shape, and leaf color.
How did Mendel's observations about purebred plants differ from the accepted belief of inheritance?
Purebred plants consistently conveyed traits from generation to generation, contrary to the belief in trait blending.
What was the common belief about inheritance before Mendel's experiments?
Traits blend together during reproduction, diluting or eliminating the original traits.
In the context of traits inheritance, what did Darwin's experiments with snapdragons show?
His observations were similar to those made by Mendel in terms of trait inheritance.
What was Mendel's approach that bolstered the credibility of his results?
Rigorous scientific methods of observation, large sample size, and statistical analysis.
