Human Biological Science Stage 2 Venusian operable bodily function 21.2 The following table represents the genotypes in the Venusian youth where B is symbolise down in the mouth fight, b symbolizing pureness scrape 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| perusal your data 1.) Because the premier(prenominal) column contains individuals that are homozygous for black skin (BB) only two out of totally(prenominal) three go to adulthood. train the number of offspring that lead live to produce the succeeding(a) gene balancen. 3individuals with black skin (BB) would survive to adulthood. 2.) Individuals with t he genotype bb volition all cease in the first year. If you stave off these individuals how numerous surviving offspring do you straightway have?

repayable to the fact that none of the purity 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? T he ratio of black skins (BB) to brown skins ! (Bb and bB) is 1:3. 4.) feature your data with the former(a) groups in the class to obtain a bigger sample. What is the ratio now?
