Which of the following statements is true about genotypes?
A) They are directly observable characteristics.
B) They always pair up in the same way across the DNA ladder rungs.
C) They are rodlike structures in the cell nucleus that transmit genetic information.
D) They are a complex blend of genetic information that influences all our unique characteristics.

Question

Quizplus · Accepted Answer

Genotypes refer to the genetic makeup of an individual, which is a complex blend of genetic information inherited from both parents. This genetic information influences all our unique characteristics, including observable traits (phenotypes). However, the genotypes themselves are not directly observable, as they exist as sequences of DNA molecules within the chromosomes in the cell nucleus. The way the DNA bases pair up in the genotypes (such as A with T and C with G) follows specific rules of base pairing, but these pairs can vary within and between individuals. Therefore, statement A and B are incorrect. Statement C is incorrect as it refers to chromosomes, which contain DNA but are not the same as genotypes.
