Meiosis and sexual Life Cycles

Genes: Genetic code inherited from parents that determines an organism's traits.

Asexual reproduction: When an organism is the only parent and passes its genes to an offspring without the use of any gametes.

Sexual reproduction: When an offspring is given a unique mix of genes from two parents.

An example of a clone.

Clone: Offspring produce in asexual reproduction.

Chromosome: Every somatic cell has chromosomes dictating certain properties. Chromosomes come in 23 sets of 2 in humans.

Haploid cell: Cell the contains a single set of chromosomes.

Diploid cell: Cell that contains two sets of chromosomes.

Triploid cell: Cell that contains three sets of chromosomes.

Meiosis: Meiosis separates one diploid cell into four haploid cells. It has phases: Prophase I, Pro-metaphase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Pro-metaphase II, Metaphase II, Anaphase II, and Telophase II. In prophase I the two chromosomes mix and intangible with each other. The remaining phases are all pretty similar to their mitosis counterpart with the same name.
