Answer and Explanation:
Mitosis is a process in which a single cell distribute into two identical cells. Mitosis include five phases which depend on the physical state of the spindle and chromosomes. Every phase of the mitosis use pipe cleaners to signify the chromosomes. Body cells have about 46 chromosomes. For simplification we use 4 chromosomes. Pipeline activity of the mitosis include different kind of material. In step 1 take two plates and stack them on the top of each other. Plates signify the cell. On the top plate, place 4 pipe cleaner. In step 2 pipe cleaner of the same length and color subsequent to each other. Then twist each pair together. “X” signify the duplicate chromosomes. Two different colors shows that one chromosome came from the mother and one from the father. Through the process of DNA duplication, chromosomes are copied. In the S stage of interphase, DNA copying take place before mitosis. When the chromosomes become visible, prophase might be identified. Then in the center of the plate, line up the chromosomes in a single line, that represent a cell in metaphase. In Anaphase, separate each chromosome by unraveling them. Telophase is the last phase of the mitosis. Cytokinesis begins in this phase. In mitosis, chromosomes goes back to the correct parent so making the data in accurate.
Answer:
A karyotype is the individuals collection of chromosomes
you can use the individuals karyotype to determine if a fetus has down syndrome by looking at chromosome 21. If the fetus has an extra copy of chromosome 21, it will have down syndrome.

Answer:
Farmers have been using selective breeding for improving their crop qualities and producing animals with better characteristics.
improved so that mankind can benefit from it.
Selective breeding is not okay on a bigger level where it might eradicate the natural varieties of plants and animals completely. When done on a larger level, the wild-type traits of plants and animals will change and be removed completely. This will lead to lesser genetic diversity.
