Answer: C
Explanation: The evidence that percentages of adenine and thymine are approximately equal and likewise that of cytosine and guanine. This is based on Erwin Charging's base composition studies. The DNA nucleotide are arranged as base with adenine on one strand forming double bonds with thymine on the complimentary strand likewise cytosine on one strand forms triple bond with guanine on the complementary
Answer:
9 out of 16 offsprings
Explanation:
This question involves two genes in guinea pig; one coding for coat texture and the other for coat color. The alleles for smooth coat (S) and black coat (B) are dominant over rough coat (s) and white coat (b).
In this question, two heterozygous guinea pigs were crossed i.e. SsBb × SsBb. The gametes produced by each parent is as follows: SB, Sb, sB, sb. Using these gametes in a punnet square (see attached image), the proportion of offsprings will be:
Smooth black coat (S_B_) = 9
Smooth white coat (S_bb) = 3
Rough black coat (ssB_) = 3
Rough white coat (ssbb) = 1
Hence, according to this question, 9 out of 16 offsprings will have a smooth black coat on average.
