Question
If a diploid cell has 20 pairs of chromosomes, there will be 20 bivalents during prophase I of meiosis.
If a diploid cell has 20 pairs of chromosomes, there will be 80 chromatids present during metaphase of mitosis.
If a diploid cell has 20 pairs of chromosmes, the organism can make 202 types of gametes if crossing-over is ignored.
Segregation of sister chromatids occurs during anaphase I of meiosis and is the physical basis of the law of segregation.
The independent movement of individual homologous chromosomes at metaphase I of meiosis is the physical basis for the law of independent assortment.
For an individual with a diploid number of 30 chromosomes, there will be 60 chromatids at metaphase I of meiosis.
For an individual with a diploid number of 30 chromosomes, there will be 15 tetrads at metaphase II of meiosis.
Which of the statements are true?
