Answer #1

Rette syndrome is mainly caused by the mutationin MECP2 gene which codes for mecp2 protein needed for the development of brain function and nervous system. Mutation chnages the little production of this protein or you can say that production in less quatity that is not sufficient.

Population genetics aspect: Rette syndrome is a genetic disorder and are very rare in population.less than 1% recorded cases are only inheritaed. It is mainly sporadic that is mutation occur randomly butnot inherited. if more than one family member have this disorder then this disorder follow the  dominant X-linked pattern.

Rette syndrom follow this pattern for X-linked dominant inheritance .

1.You are studying a familial breast cancer gene. All previous pedigree data indicate that this type of cancer is inherited as autosomal dominant trait. Still, in some instances the cancer skips a generation. If this breast cancer is autosomal dominant, what is a likely explanation as to why it skipped a generation sometimes? a. Skipping generations is common in autosomal dominant traits. b. This breast cancer is not 100% penetrant. c. Only the environment can cause cancer. d. No reasoning...

5. The Triple Blood Test screens pregnant women for the genetic disorder, Down syndrome. This syndrome occurs in about 1 in 800 live births and arises from an error in cell division that results in a fetus having an extra copy of chromosome 21. The chance of having a baby with Downsyndrome increases after a woman is 35 years old. A study (J. Haddow et al.,New England Journal of Medicine, vol. 330, pp. 1114-1118, 1994) of5282 women aged 35 or...
