#Question id: 20401

There were four rules of parity given by Erwin Chargaff 
1) Base A in one strand of the duplex is matched by (T) in the other strand, and base G in one strand of the duplex is matched by a complementary base (C) in the other strand
2) equal amounts of A and T, and equal amounts of C and G, in each single strand of the duplex. 
3) Purines in non-template strand applies more closely to Exons
4) GC content tends to be greater in exons than in introns
choose the correct option regarding rules

#Unit 8. Inheritance Biology

In humans, albinism (unpigmented skin, hair, and eyes) is due to an enzymatic deficiency, and it is an autosomal recessive trait. Suppose that in a small country of one million people (“Generation 1”), there are 500 aa albinos and 9000 Aa heterozygous carriers. What is the probability that a child will be albino if: Both parents are members of Generation 2, and one parent is albino and the other is non-albino.
