Quizplus · Accepted Answer

Since both parents are carriers of the genetic disorder, it suggests that the condition is autosomal recessive, meaning that the allele causing the disorder is on an autosomal chromosome. Sex-linked disorders are typically X-linked, and since the parents are not male, this is not likely the case. Incomplete dominance refers to a situation where the heterozygous phenotype is intermediate between the dominant and recessive phenotype, which is not evident in this Punnett square. Lastly, linkage refers to the tendency of alleles on the same chromosome to be inherited together, which is also not apparent in this scenario. Therefore, the best answer is A.
