23. A) A chicken has 78 chromosomes in its somatic cells; how many chromosomes did the chicken inherit from each parent? B) How many chromosomes are in each of the chicken’s gametes? C) How many chromosomes will be in each somatic cell of the chicken’s offspring? D) How many chromosomes are in a set? A) 39 B) 39 C) 78 D) 39 24. True or false? A haploid organism has one pair of homologous chromosomes. 25. Seedless watermelons are triploid, which prevents normal meiosis from taking place. Triploid (3n) watermelons are produced by crossing a tetraploid (4n) strain with a diploid (2n) plant. Briefly explain why this mating produces a triploid individual. Why can mitosis proceed normally in triploid cells, when meiosis cannot? To get you started, here’s a diagram outlining how get triploid individual – it is the gametes of this individual that we are concerned with (why can this individual not produce viable embryos?)
26. At the conclusion of mitosis, each daughter cell has 27. Early in mitosis, chromatin condenses into the compact, rodlike structures known as chromosomes. Which of the following processes takes place more easily as a result? A. replication of DNA B. orderly distribution of DNA into 2 new nuclei C. disintegration of the parent cell 28. Each of the daughter cells that result from the normal mitotic division of the original parent cell contains 29. The cells produced by mitotic divisions are considered to be:
