second paragraph.
I believe the correct answer is A. because mz twins are more likely than dz twins but this question reads as dz twins, mz twins, so dz should be less likely. Mz twins are 96% and dz is 24% to develop the same illness.
To determine the correct answer, we need to understand the meaning of concordance rates and the difference between dizygotic (DZ) and monozygotic (MZ) twins in relation to autism.
Concordance rates refer to the probability that both twins in a pair will develop the same illness or condition. In this context, we are specifically looking at autism.
Dizygotic (fraternal) twins occur when two separate eggs are fertilized by two different sperm, resulting in two genetically distinct individuals. Monozygotic (identical) twins, on the other hand, occur when a single fertilized egg splits into two embryos, resulting in genetically identical individuals.
Now, in terms of autism, numerous studies have been conducted to compare concordance rates in DZ and MZ twins. These studies help us understand the genetic contribution to the development of autism.
If MZ twins have a higher concordance rate for autism than DZ twins, it suggests a stronger genetic influence on the development of autism. Conversely, if MZ twins have a lower concordance rate than DZ twins, it suggests that non-genetic factors play a significant role in the development of the condition.
Based on this understanding, let's examine the answer choices in relation to the question:
A) Significantly less: This option suggests that MZ twins are less likely than DZ twins to develop the same illness. However, the question implies that MZ twins are more likely to develop the same illness, so A is incorrect.
B) Somewhat less: This option implies that MZ twins are somewhat less likely than DZ twins to develop the same illness. However, the question suggests that MZ twins are significantly more likely to develop the same illness, so B is incorrect.
C) Significantly more: This option suggests that MZ twins are significantly more likely than DZ twins to develop the same illness. This aligns with the question's implication, so C is the potential correct answer.
D) Somewhat more: This option suggests that MZ twins are somewhat more likely than DZ twins to develop the same illness. However, the question implies that MZ twins are significantly more likely to develop the same illness, so D is incorrect.
Given the analysis, it appears that the correct answer is C) significantly more likely.
