Yes they are, zygotes themselves are the product of fusion between two haploid gametes. These gametes fuse in order to develop into a multicellular structure, which they are unable to do unless they fuse. The product of their fusion is a zygote which is able to develop into a multicellular structure.
If the two different sources of DNA are a sperm and egg cell, they produce a diploid organism, which means that it has two sets of chromosomes in its body cells.
Gametes are haploid, meaning they contain half the genetic material of normal (somatic) cells. This is so that when the two different gametes fuse (during sexual reproduction), the resulting organism will once again have the correct amount of chromosomes - half from each gamete.
The diploid cell that results from fertilization is called a zygote. It is a product of the fusion of two haploid gametes, the sperm and the egg.
zygote
This is because during meiosis there is (mostly) genetic variation by means of crossing over, independent assortment and mutations. As two gametes are being fused, the end product will be different from the parent, because the factors mentioned above ensure this. For a bit more info: The end product might not always be different as sometimes (in a very rare case), independent assortment and mutations might not occur to the two gametes which are to be fertilised, and if the two gametes both contained chromosomes on which crossing over did not occur, and if these two gametes were to fertilise, then the product would be genetically the same as the parent plant.
An RRYy parent can form two different gametes: an RY and an Ry
The products of meiosis are called Gametes.
Gametes are produced by meiosis. If the male and female gametes are produced by two different individuals, sexual reproduction combines inherited
The two different sources are primary and secondary sources
Four can be formed RY, Ry, rY and ry.

Only two different gametes (sex cells) can be created using a combination of AabbCCdd. This is because Aa is the only gene with two different alleles (A and a). The other genes have two copies of the same allele - therefore that is all that the gamete can contain. So the two different gametes possible are: AbCd and abCd

Meiosis. Mitosis is in somatic sells(non gametes/non sex cells) , and meiosis occurs in gametes/sex cells.
The two types of gametes that could result from the AABb allele combination are AB and Ab. This is because during meiosis, homologous chromosomes separate and randomly assort, leading to different combinations of alleles in gametes.
