Why is there no genetic dominance for traits in the mitochondrial genome? a.)Mitochondrial mutations are always recessive. b.)There is no diploidy in the mitochondrial genome. c.)The dominant alleles were selected out of the population. d.)There isn't enough mitochondrial DNA in each cell for any gene to dominate.

d.)There isn't enough mitochondrial DNA in each cell for any gene to dominate.

Hope this helps :)

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.
