3 parts of the cell cycle?
Mitosis,Meiosis,and Amitosis
When do organisms complete meiosis?
Organisms complete meiosis during the formation of gametes, which are specialized cells involved in sexual reproduction. In humans, meiosis occurs during the formation of eggs in females and sperm in males.
How many chromosomes are present in a mosquito cell at each what stages Meiosis?
A mosquito cell has 6 chromosomes in total. During meiosis, the cell goes through two rounds of division. In meiosis I, the cell reduces its chromosome number to half (3 chromosomes) and in meiosis II, it divides again to produce four daughter cells, each with 3 chromosomes.
What are nondisjunction genes?
Nondisjunction is the failure of homologous chromosomes or chromatids to segregate during mitosis or meisos with the result that one daughter cell has both of a pair of parental chromosomes or chromatids and the other has none. An example is Trisomy 21, which is also called Down's Syndrome. This person has 3 chromosome #21.Nondisjunction of genes occur during meiosis I when homologous chromosomes fail to separate or during meiosis II when there is unequal distribution of chromosomes. This leads to aneuploidy.
How many sex cells does meiosis produce?
Four gametes are produced every time a cell goes through the process of meiosis. For females, the four become an egg(zygote).
