HELP WITH BIOLOGY QUESTIONS ITS URGENT

-What does it mean that individual "1" is shaded?

-How are persons 1 and 8 related to each other?

-Which two people are not genetically related to this family?


-also The pedigree above represents the abnormal allele which causes sickle cell disease. Sickle cell disease causes red blood cells to contort into a sickle shape. The cells die early, leaving a shortage of healthy red blood cells (sickle cell anemia), and can block blood flow causing pain (sickle cell crisis). It is a recessive allele. If  we use "N" to represent normal hemoglobin, and "n" to represent the sickling hemoglobin, what is the genotype of individual number 1? (choose from below)



NN

Nn

nn

1 could be either Nn or nn
