Like bacteria(prokaryotes), eukaryotic organisms can develop mutations in DNA that can affect traits, but these mutations are rare. Unlike bacteria, most multicellular organisms reproduce sexually- that is, two parents each produce cells called gametes that contain 1/2 the DNA needed for an organism. When gametes from two separate parent organisms fuse to form a single cell (zygote), that will develop into a juvenile, that is not identical to its parents. Identify THREE events in the process of creating gametes and forming a zygote that result in this natural variation.

Kara has a plant that produces either purple or white flowers. she crosses a plant that has two recessive alleles for white flowers with a plant that has two dominant alleles for purple flowers. which result would be true of all of the offspring? a) all of the offspring would have two recessive alleles and white flowers. b) all of the offspring would have two dominant alleles and purple flowers. c) all of the offspring would have one recessive allele, one dominant allele, and white flowers. d) all of the offspring would have one recessive allele, one dominant allele, and purple flowers
