Explanation:
Gametes are the sex cells or reproductive cells that are haploid in number. Gametes carry only one allele of each gene or chromosome in any organism. The male gamete called an egg or ovum whereas the male gamete called sperm or pollen.
In this case, the heterozygous plant has the genotype RrYy. In each of the gametes, there would one allele of each gene. The gametes get a dominant R and a dominant Y allele and a recessive r and a recessive y allele. Each produces 25% each of RY, Ry, rY, and ry.
When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor.

Saturated fatty acids are chains of single bonded carbons surrounded by hydrogen atoms.
Unsaturated fatty acids have bent structures due to double bonding between carbon atoms in the chain. When carbons create double bonds with each other they are no longer able to hold as many hydrogens as a saturated fatty acid
