He simplified the problem by looking at only one or two traits at a time. He focused on traits that existed in two easily distinguishable forms. He was the first to quantitatively examine the behavior of chromosomes during the formation of gametes. He chose an organism where many pure varieties were available. He chose an organism that was easy to grow and that had a short generation time. He chose an organism that had a few large chromosomes rather than many small chromosomes. He collected quantitative data and mathematically analyzed his results. He examined large numbers (hundreds) of offspring over several generations. He was the first to produce hybrids by crossing different varieties of the same species. He chose an organism where he could easily control whether self-fertilization or cross-fertilization took place. He was the first to study the DNA of the organisms he crossed rather than just their external appearance.Explanation / Answer
A, at end of telophase II cells will have half the amount of chromosome as both parents thus, 1/4th of mother and 1/4th of father.
B. at metaphase 1
C. focused on traits that existed in two easily distinguishable form.
easy to grow with short generation time.
organism had many pure varieties available.
quantitative data collected and mathematically analyzed results.
examined large number of offsprings over several generations.control of self fertilization and cross fertilization was possible.
