The diagram above shows homologous chromosomes during prophase I of meiosis. Which of the following correctly describes the process being illustrated?
Mutation in which the DNA content of the gene is altered
Segregation of sister chromatids
Condensation and segregation of alleles
Crossing-over in which alleles are exchanged
The table lists the typical diploid number of chromosomes of several different organisms.
Which of the following is the best explanation for why the chromosome number is an even number in each of these organisms?
The diploid chromosome number is always even so that when mitosis occurs each new cell gets the same number of chromosomes.
It is only a coincidence; many other organisms have an odd number of chromosomes.
The diploid chromosome number represents pairs of chromosomes one from each parent, so it is always an even number.
Chromosomes double every time the cell divides, so after the first division, the number is always even.
Which diagram best represents mitotic cell division?
