Comments Comment: Question 11 Complete Mark 1.00 out of 1.00 Flag question Question text Why did the ebony body color disappear in the F1 Generation and reappear in the F2 Generation? In F1, the dominant gene from the Homozygous dominant prevents them from showing themselves. F2, the characteristics reappear in the offspring which inherit the two the recessive genes.

What caused the difference? Came close to the expected results..... Allele made the difference gametes Comments Comment: What caused the difference? Chance Question 6 Complete Mark 1.00 out of 1.00 Flag question Question text What fraction of actual BB, Bb, bb did you record? How close is it to the expected ration Mendel predicted? 12.5 for BB 25 FOR Bb 12.5 for bb From my understanding of the Mendel law the heterozygous fraction is more than the two homozygous Comments Comment: Question 7 Complete Mark 1.00 out of 1.00 Flag question Question text Based on the parents' genotypes, what is the phenotypic ratio expected from a dihybrid cross between the two parents for these traits? The phenotypic ratio from a dihybrid cross will be- widow's peak and smooth chin, widow's peak and cleft chin, straight hairline and smooth chin, straight hairline and cleft chin = 9:3:3:1 Comments Comment: Question 8 Complete Mark 1.00 out of 1.00 Flag question Question text Toss all 4 coins together 50 times and keep a tally sheet while doing so.

The actual results are close to the expected results, differences may occur because of the nature of the experiment Comments Comment: Question 11 Complete Mark 1.00 out of 1.00 Flag question Question text What fraction of actual phenotypes did you record, i.e. how many widows peak and smooth chin, no widows peak and cleft chin, etc? How close is it to the expected ration Mendel predicted? Widow's peak and smooth chin expected/actual fraction:3/5 and 3/5 widow's peak and cleft chin expected/actual fraction:1/5 and 1/7 straight hairline and smooth chin expected/actual fraction: 1/5 and 1/5 straight hairline and cleft chin expected/actual fraction:1/16 and 1/16 It is mostly the exact equal to the Mendel’s expected ratio
