If plants with wrinkled seeds are 100% selected against, how many generations would it take to remove a recessive allele? Explain (round seeded plants are either RR or Rr)

Expert Solution

Here, the given character for the seed is shape of the seed. their are two possibility for this character. Seed may either be round or wrinkled. The genotype assigned for the wrinkled seed is rr, whereas for the round seed; two possibilities are their RR or Rr.

Now, the selected seed was already given as the wrinkled. So, for removal of the recessive allele rr, It must be crossed with either homozygous dominant RR, or heterozygous dominant Rr. Since there are two different combination in other side of parents (RR or Rr), two possibilities are arised. Either rr is crossed with RR or Rr.

Mendel crossed pea plants that had yellow-round seeds with plants that had green-wrinkled seeds. The first generation produced plants with all yellow-round seeds. Self crossing of these plants produced the following F2 phenotypes: Yellow-Round Yellow-wrinkled Green-round Green-wrinkled Count 315 101 108 32 The expected phenotypic ratio is 9:3:3:1 1. What are the null and alternate hypotheses for the chi-square goodness of fit test? 2. What are the expected counts under the null hypothesis? 3. Determine a chi-square test statistic and...

How many grams of steam at 100 deg.Celsius would be required to raise the temperature of 43.6 g solid benzene (C6H6) from 5.5 oC to 30.0 oC? Assume that heat is only transfered from the steam (and not liquid water) and that the steam/water and benzene are seperated by a glass wall and do not mix. (The melting point of benzene is 5.5 oC; ΔHfus for benzene is 9.87 kJ/mol; specific heat for benzene is 1.63 J/g ooC; ΔHvap for...
