The trait for 'black feet in ferrets' is a recessive trait encoded for by "f". White feet is encoded for by a dominant allele encoded for by the letter "F".

An ecological study in ferret country conducted by Mrs. Wright found that out of 1000 ferrets:

360 had black feet
480 had white feet and were heterozygous
160 had white feet and were homozygous.

Using this information find the allele frequencies for F and f.

Remember "F" = p and "f" = q

a
F = 0.4 and f =0.6
b
F = 0.7 and f = 1
c
F = 1 and f =0.7
d
F = 0.7 and f =0.3

events in order:

1.       vishnu schist

2. zoroaster granite

3. bass limestone

4. hakatar   shale

5. igneous intrusion

6. shinumo quartzite

7. dox sandstone

8. tapeats limestone

9. bright angel shale

10. muav limestone

11. temple butte limestone

12. redwall limestone  

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
