A mutation in a collagen gene is likely to affect the phenotype because
A)it is extremely rare.
B)during meiosis,the chromosome that bears the mutation is more likely to enter a gamete than the chromosome that carries the wild type allele.
C)collagen has a very precise three-dimensional structure,so nearly any disruption alters the overall conformation.
D)people who use cosmetics with collagen silence collagen genes.

Quizplus · Accepted Answer

Collagen has a very precise three-dimensional structure, so nearly any disruption alters the overall conformation. This can lead to a variety of phenotypic effects, such as skin laxity, joint problems, and weakened bones. Choices A, B, and D are incorrect because they do not accurately reflect the nature of collagen mutations or their effects on the phenotype.
