White spotting (w) is a dominant trait for coat color in cats. the recessive allele (w) produces no white spots in the coat hairs. the homozygous dominant genotype (ww) produces white spots that cover most of a cat’s coat. the heterozygous genotype (ww) produces smaller white spots in a cat’s coat. suppose that a cat breeder wants to make a make with a mostly white spotted coat with a female with only a few small white spots.
1). describe the male cat’s genotype in symbols and words.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.

meiosis is the first to occur after the nuclei of opposite of opposite mating types fuse
