WebThus, when one observes differences in some phenotype among plants in a field, some of that phenotypic variance may be because those plants possess different genotypes for that trait (genetic variance) and some may be the result of the plants having different micro-environments (environmental variance). The genotype of an organism is its complete set of genetic material. Genotype can also be used to refer to the alleles or variants an individual carries in a particular gene or genetic location. The number of alleles an individual can have in a specific gene depends on the number of copies of each chromosome found in that species, also referred to as ploidy. In diploid species like humans, two full sets of chromosomes are present, meaning each individual has two alleles for any give…
