Webhomothallic reproduction, a meiotic method involving one parent. Homothallic reproduction generates less variation than heterothallic reproduction, as it involves only a single genome, not two like heterothallic sex. This means ascospores and conidia of A. nidulans contain the same genetic information. Web24 mrt. 2011 · The two-stage process of meiosis begins with meiosis I, also known as reduction division since it reduces the diploid number of chromosomes in each daughter cell by half.
