Human Biological Science Stage 2 Venusian concrete bodily function 21.2 The following table represents the genotypes in the Venusian egress where B is symbolise down in the mouth fight, b symbolizing pureness peel off while Bb and bB symbolizes brown skin. | BB| Bb| bB| bb| 1| | | ?| | 2| ?| | | | 3| | ?| | | 4| | | | ?| 5| | ?| | | 6| | | | ?| 7| ?| | | | 8| | | ?| | 9| | ?| | | 10| | ?| | | nub| 2| 4| 2| 2| 11| | | ?| | 12| | | | ?| 13| | | | ?| 14| | | | ?| 15| | ?| | | 16| | ?| | | 17| ?| | | | 18| ?| | | | 19| ?| | | | 20| | | | ?| Total| 5| 6| 3| 6| poring over your data 1.) Because the premier(prenominal) column contains individuals that are homozygous for black skin (BB) only two out of all(prenominal) three go to adulthood. figuring the number of offspring that lead live to produce the nigh gene balancen. 3individuals with black skin (BB) would survive to adulthood. 2.) Individuals with the genotype bb lead all bump in the first year. If you stave off these individuals how many a(prenominal) surviving offspring do you straightway have?

payable to the fact that none of the snow-white skin individuals (bb) will die in the first year, no white skin individuals will survive to adulthood. Therefore we need to eliminate all white skin individuals and 1/3 individuals with black skin that would not survive the results showed that we have a symmetry of 12 individuals. This endurance can be shown in a proportion of 12/20. 3.) What is the ratio of black skins to brown skins that survive to adulthood ? The ratio of black skins (BB) to brown sk! ins (Bb and bB) is 1:3. 4.) feature your data with the some other groups in the class to obtain a bigger sample. What is the ratio now?
