In a diploid cell with four chromosomes (two homologous pairs), there are two equally possible ways for the chromosomes inherited from the two parents to be arranged during metaphase I. This variation in the orientation of chromosomes leads to gametes with four equally possible combinations of chromosomes.
Chromosomes
The thread-like components known as chromosomes are found in the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA). DNA is passed down from parents to children and contains the precise instructions that give each kind of living thing its individuality.
The Greek words for colour (chroma) and body are where the word "chromosome" originates (soma). Because chromosomes are cell structures or entities that are intensely stained by several vivid research dyes, scientists gave them this moniker.

The algae living in the tissues of coral animals are called photosynthetic algae. The purpose of the the photosynthetic algae is to produce oxygen and help the coral to remove wastes. Coral on the other side provides the algae with a protected environment and compounds they need for photosynthesis. The algae supply the coral with the product from the photosynthesis which are glucose, glycerol, and amino acids.

The production of sperm and egg cells are an indication that meiosis took place in the life cycle of a jellyfish. Gametes, or sex cells are produced in meiosis. Another indication is based on the legend in the phase 1 arrow, is haploid. The result of meiosis is also haploid, while in mitosis it is diploid.
