When plants that are heterozygous for round seeds are crossed, what is the probability that the offspring will have wrinkled seeds?

Ans.

Heterozygous plants are those plants that have two different alleles for a particular gene or trait. The garden pea plant shows two alternative seed shape, round and wrinkled. The allele for round shape is denoted by 'R", which is dominant trait over recessive allele for wrinkled shape ('r').

When plants heterozygous for round seeds (Rr) are self-crossed, two types of gametes are formed, R and r. The resulting offspring show both round (75%) and wrinkled (25%) seeds.

Thus, 25% offspring will show wrinkled seeds as there is one wrinkled plant out of four offspring plants as shown in Punnett square below:

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.
