Mendel's first law
You won't get too far in your fly experiment if you don't know about Mendel's laws . These laws describe the fundamental principles of inheritance . Amazingly, Mendel figured this all out by studying pea plants (over 10,000 for 10 years) way before DNA and Genes were understood. Mendel first reported these laws in 1865 but they faded into obscurity until they were rediscovered in 1900. A couple of definitions: GENOTYPE = What genes a cell contains PHENOTYPE = T he characteristics/traits of an organism Anyway, that is enough preamble --> to the laws.... Mendel's First Law: The Law of Segregation Every individual has a pair of genes (alleles) for any particular trait. Each parent passes on only one allele to each of their gametes - by meiosis. Gametes randomly come together, hence offspring will have again two alleles for a particular trait, one from their moth...
