What is the difference between heterozygous and homozygous? What is the difference between monosomy and trisomy? What is the difference between genotype and phenotype? 4, What is the difference between mitosis and meiosis? 2 1. Being homozygous for a particular gene means you inherited two identical versions. It's the opposite of a heterozygous genotype, where the alleles are different. 2. Trisomy disorders occur when you have an extra copy of a chromosome. Monosomy occurs when you are missing a copy of a chromosome 3. 4. A person's genotype is their unique sequence of DNA. More specifically, this term is used to refer to the two alleles a person has inherited for a particular gene. Phenotype is the detectable expression of this genotype – a patient's clinical presentation. Mitosis is a process where a single cell divides into two identical daughter cells (cell division). facts What is meiosis? Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information.
