Based on this pedigree, what are the most likely genotypes of individuals I-1 and 1-2? When entering the answer use AA, Aa, or aa.
Individual l-1 genotype=
Individual 1-2 genotype=

PLEASE HELP!

I-1 genotype = AA or Aa

I-2 genotype = aa

Explanation:

The trait in question is autosomal and dominant. Let us assume that the trait is represented by the allele A, the alternative form would be a.

I-1 individual is affected for the disease, hence he is either true-breeding AA or heterozygous Aa.

I-2 individual is not affected for the disease, hence, she can only be aa. For an autosomal dominant trait, an individual is either affected or free from the trait. There is no chance of being a carrier. Heterozygous individuals are affected for the disease.

Therefore;

I-1 genotype = AA or Aa

I-2 genotype = aa

the answer is d.) homologous; have mammary glands

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.
