Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unit to form single cell for sexual reproduction. During reproduction, when the sperm and egg unit to form a single cell, the number of chromosome is restored in the offspring.
Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.

Explanation:
Spring tides
When the Sun, the Moon and The Earth, all are arranged in straight line.Due to gravitational pull of Sun and Moon these tides are occurred.These tides occur twice in a lunar month regardless to any season.

Neap tides occur when the Sun and the Moon form right angles with the Earth
So, the given figure represent Spring tide.
