3. Compare and contrast mitosis and meiosis, focusing on key steps that account for the differentoutcomes of these two processes4. Distinguish between the life cycles of diploid-dominant species, haploid-dominant species, andspecies that exhibit an alternation of generations.Diploid dominantoMeiosis occurs n cells within testes or ovaries to produce haploid gameteoDuring fertilization, sperm and egg unite to form a diploid zygoteoRepeated mitotic cell division produces a diploid multicellular organismHaploid dominantoCertain haploid cells act as reproductive cellsoHaploid reproductive cells unite to form diploid zygoteoMeiosis of the zygote produces 4 haploid sporesoRepeated mitotic cell division produces a haploid multicellular organismAlternation of generationsoCertain cells in the diploid sporophyte undergo meiosis to produce haploid sporesoRepeated mitotic cell division produces a haploid multicellular organism (gametophyte)oCertain cells within the gametophyte differentiate into gametesoTwo gametes unite during fertilization to form a diploid zygoteoRepeated mitotic cell division produces a diploid multicellular organism (sporophyte)15.4 Variation in Chromosome Structure and Number1.
