Humans have total chromosomes, which are arranged in pairs. Each pair consists of chromosomes, which are chromosomes that are similar in shape, size, and genetic content but may carry different versions of the same genes.
Crossing over occurs during , which is the process that produces gametes. Before both mitosis and meiosis, happens, where the cell prepares by growing and replicating its DNA (G1, S, G2 phases). cells (body cells) divide through to produce genetically identical cells for growth and repair. Gametes have half the amount of DNA as somatic cells, containing only chromosomes (no pairs) instead of the usual 46 chromosomes in somatic cells. This is because gametes undergo meiosis, reducing the chromosome number by half.
Which of the following cells below is haploid?
At the end of mitosis, there are daughter cells that are .
