Based on its location on the periodic table, how many electrons does oxygen have in its outer energy level? a 3 b 4 c 5 d 6

D

Explanation:

Oxygen has 6 valence electrons and it is in group 16 on the periodic table

If 1 of 10,000 persons is affected, q2 = 1/10000 = 0.0001

The frequency of hemophilia allele is q = 0.01

p + q = 1, so p = 1 – 0.01 = 0.99

The frequencies of alleles for hemophilia are p = 0.99, and q = 0.01, where p is the negative allele for hemophilia, and q is the positive allele for hemophilia
