Question

Quizplus · Accepted Answer

Deletion refers to the loss of a part of a chromosome, and in the case of cri-du-chat syndrome, it is caused by a deletion in chromosome 5.

Answer: G
 A gene is a unit of DNA that contains the instructions for making a specific protein or RNA molecule, and mutations in certain genes can lead to genetic disorders like cri-du-chat syndrome.

Answer: I
 Autosomes are the non-sex chromosomes (chromosomes 1-22 in humans) that carry most of the genetic information in an individual's genome, including the genes involved in the development of cri-du-chat syndrome.

Answer: F
 Phenotype refers to the observable characteristics (physical, biochemical, or behavioral) of an individual that result from the interactions between their genotype and environment, and the cri-du-chat phenotype includes distinctive facial features, low birth weight, intellectual disability, and a high-pitched cry.

Answer: A, C
 Codominance and incomplete dominance are both types of inheritance patterns that result in a blending of traits in heterozygous individuals, and they are not relevant to the cause of cri-du-chat syndrome.

Answer: B, J
 Duplication and linkage both refer to the way that genes or segments of chromosomes are arranged and passed on from one generation to the next, and neither of these processes are involved in the cause of cri-du-chat syndrome.
