Answer:
Given that, both parents are heterozygous. Now, the chances for one child to inherit one defective gene from each parent = ½*1/2 =¼.
Similarly, the probability of being affected by albinism =Probability of inheriting one defective gene from each parent = ½*½ = ¼
The probability of not being affected = 1- the probability of being affected = 1-1/4 = ¾.
Now, the chances of not being affected by both albinism and sickle cell anemia = ¾*3/4 = 9/16.
The probability of neither twins be affected = 9/16*9/16 =81/256.

Answer:
D. Nitrogen-14 has 7 electrons, 7 protons, 7 neutrons nitrogen-15 has 7 electrons, 7 protons, and 8 neutrons
Explanation:
In an atom, number of electrons is equal to the number of protons. And the number of neutrons is equal to the difference between the mass number of the atom and the atomic number. For Nitrogen 14, electron is 7, proton is also 7 as number of electrons and number of protons are equal. So, the neutron will be 14-7= 7. For Nitrogen 15, electron number is 7 so proton number will be also 7. Neutron number for nitrogen 15 will be 15-7= 8. That's why the answer is option number 4.
