• unique
• haploid
• zygote
• identical daughter cells
• mitosis

Answer:

Meiosis is a process in which sex cells, also known as gametes are made. Meiosis is different from mitosis in a lot of ways, one being that mitosis creates identical daughter cells and meiosis creates unique daughter cells. Meiosis is important because it allow for the creation of a meiosis nucleus. Cells produced by meiosis will be used in haploid, where each member of the next generation is genetically unique.

Cells produced in sexual reproduction will have half of the genetic information of body cells and will be genetically unique. This is necessary because when a sperm and an egg fuse together in sexual reproduction. They form a zygote: the first body of a new individual.

The new individual will now have cells that are diploid, meaning they have two sets of chromosomes. They zygote will have to do a lot of mitosis allowing it to grow quickly and ensure that all of its cells are genetically unique.

Mitochondria are cell structures that contain a small quantity of DNA.
Scientists are sequencing the DNA of one particular gene in mitochondria to
help identify different species of many animals including myriapods. The
sequences that they find are called ‘barcodes’.
(i) State the part of the cell that contains most of the DNA.
[1]
(ii) Suggest how DNA barcoding might be useful in the classification of animals,
such as myriapods.
