Answer: Option D. The maternally inherited chromosome 15
All paternally imprinted genes are "deactivated" epigenetically, allowing only one functional copy to remain, which is inherited from the mother. If this copy is defective, it causes syndromes such as Angleman's syndrome.

Prader-‐Willi Syndrome occurs when a region of chromosome 15 is deleted from the paternal copy; whereas Angelman Syndrome occurs when this region is deleted from the maternal chromosome. The difference in effect is due to both maternally and paternally imprinted genes being present in this chromosomal region. 1.) Are the maternally imprinted genes associated with Prader-‐Willi or Angelman? What about the paternally imprinted genes? How do you know? 2. A couple produces two children with Angelman Syndrome. Although people with...

D Question 22 Identify a FALSE statement about X chromosomes: a) X chromosome inactivation occurs in all somatic cells of females. b) Xist inactivates only the maternally inherited X chromosome. The inactiveX chromosome is coated with Xist transcripts. di X chromosome inactivation does not occur in males. In early cleavage stage embryos, both X chromosomes are active.

4. You are working on a certain species of worm, with an ZZZW sex determination system. You perform karyotype analysis for a mating pair, but you don't know which one is the male and which one is the female. Which one would you guess is the female (left or right?) (2points) ) 5. Different genes are located on different kinds of genetic elements - autosomes, W chromosomes, the mitochondrial genome, etc. Different elements are transmitted in different ways, so different...
