Human gametes
WebThis phenomenon is called genetic linkage. When genes are linked, genetic crosses involving those genes will lead to ratios of gametes (egg and sperm) and offspring types … Weball gametes are genetically different from each other During fertilisation, two haploid gametes fuse to form one diploid cell. This will divide by mitosis to form an organism.

In wheat ( Triticum aestivum ), somatic cells are hexaploid, having 42 chromosomes (that is, 6 full sets of 7 chromosomes). When a wheat cell perform meiosis (producing micro and mega spores, and later on gametes), it produces haploid cells which are triploid. Wheat gametes are haploid and triploid.
WebThe two gametes (sperm and ovum) contain 23 chromosomes (n) each and when the sperm fertilizes the egg (ovum), the zygote now has a total of 46 chromosomes and becomes diploid (2n). This zygote then goes through many stages of the replication cycle to create more and more cells called somatic cells or body cells.
