Are gametes cells?
Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.
Does meiosis produce gametes?
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. … Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.

Are mules alive?
The conclusion is the following: mule is a living individual, because it is a part belonging to an evolving population. To be precise, a mule—considered as a vehicle of survival—is a living object, because of owning the genes which constitute a part of an evolving gene pool.
