In the Congo, 4% of newborns have sickle-cell disease, a recessive trait. In a population of 1000 individuals, how many would you expect to be homozygous dominant, heterozygous, and homozygous recessive (SS, Ss, ss)?

Homozygous dominant would be 480.

Heterozygous would be 480.

Homozygous recessive would be 40.

Explanation:

In order to find how many would have the disease (homozygous recessive) you would have to multiply the population by the percentage affected (4% or .04). Then subtract 40 from 1000 and get 960. Then you divide that by 2 and get 480.

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.

the correct answer in apex is tissue development, i know because i just had this question
