It is typically used because it is an animal species that is easy to care for, has four pairs of chromosomes, breed quickly, and lays many eggs. Gregor Mendel created two main laws prior to his experiments with his growing pea plants. In mammals, the Y chromosome contains the gene SRY, which triggers testis development. The first law he created is the law of segregation. You will need to be able to tell the males 2. The answer to the question determines what color to use on the fruit fly at the bottom of the page.

Half the gametes carry one allele, and the other half carry the other allele. Wild Type Female x Vestigial Winged Male, Wild Type 23 What is the fruit fly's diploid number? It states that the two members of a gene pair (alleles) segregate (separate) from each other in the formation of gametes. Probability (p) The members of a homologous pair separate in meiosis, so each sperm or egg receives just one member. Allowing for some deficiency in recessives, this was not unlike what Mendels theory predicted. You'll get a detailed solution from a subject matter expert that helps you learn core concepts.

It offers a choice of three crosses for analysis: monohybrid, dihybrid, and sex-linked. 4. What were the key factors that influenced the outcomes?). Drosophila genome is 60% homologous to that of humans, less redundant, and about 75% of the genes responsible for human diseases have homologs in flies (Ugur et al., 2016). The first mutant white allele isolated (called w1) arose spontaneously because of transposon insertion. The other is the X chromosome.
