Question

How can haploid organisms produce gametes?

Answer 1

Gametes are created by meiosis (reduction division), in which a germ cell is subjected to two fissions, resulting in four gametes being produced. Male and female gametes combine during fertilization, forming a zygote diploid (i.e., having paired chromosomes).

Complete answer:
They should, but not alone, through isogamy. Like themselves, they need another cell. Isogamy is a mode of sexual reproduction that includes gametes of similar morphology (similar shape and size), varying only in allele expression in one or more mating-type regions.

Since both gametes look similar, they should not be defined as "male" or "female." Instead, it is said that species undergoing isogamy have separate forms of mating, most generally referred to as strains "+" and "-". But remember that what are called gametes are created by them. This type occurs in algae and yeasts, for instance. Before the kind we are familiar with, this type of reproduction happened (egg and sperm).

The consistency of a cell or organism that has a single chromosome set is haploid. There are haploid organisms which reproduce asexually. Diploid species that replicate sexually are (having two sets of chromosomes, one from each parent). Among females, there are only haploids in their eggs and sperm cells.

Note: Reproductive cells or sex cells that join to form a new cell called a zygote during sexual reproduction are gametes. Ova, compared to the male gamete, are non-motile and comparatively large. Pollen is a male sperm-producing gametophyte in seed-bearing plants, and female sex cells are found within plant ovules.
