AnaPhase1
what happens during meiosis that results in a defect characterized by the deletion of chromosomes
The tetrads are pulled apart.
Chromosomes make copies of themselves once during meiosis. This occurs during the S phase of interphase, which happens before meiosis I.
It happens during interphase of the cell cycle.

In Meiosis I: Separates homologous chromosomes In Meiosis II: Separates sister chromatids
During meiosis I, homologous chromosomes pair up and exchange genetic material through crossing over. The homologous chromosomes then separate, reducing the chromosome number by half. During meiosis II, sister chromatids separate, resulting in the formation of four haploid daughter cells, each with a unique combination of genetic material.
A total of four daughter cells form
The pairing up of maternal and paternal chromosomes during meiosis happens in the prophase I stage. This pairing is called synapsis and results in the formation of a structure called a tetrad.
According to mendel's law of segregation, what happens to chromosomes during meiosis is that, allele pairs do separate leaving each and every cell with a single allele for each trait.
