While DNA testing as we know it was refined between the 1950s and 1980s, there were forms of genetic testing done as early as 1886. 1994 The first GMO produce created through genetic engineering—a GMO tomato—becomes available for sale after studies evaluated by federal agencies proved it to be as safe as traditionally bred tomatoes. 1982 FDA approves the first consumer GMO product developed through genetic engineering: human insulin to treat diabetes.
There's 2 alleles for every quality and there are 3 qualities. The likelihood of acquiring the fatherly allele of those 3 qualities would be 1/2 x 1/2 x 1/2. This is on the grounds that you have a 50/50 possibility of getting the allele from your mom or your dad for three unique alleles. Since you are making sense of the likelihood of acquiring 3 qualities from your dad you duplicate at that point to get 1/8.
