In Caenorhabditis elegans, the level of expression of genes on both X chromosomes of females is reduced by half.
What phenomenon is this an example of?
A. extra-nuclear inheritance
B. genomic imprinting
C. dosage compensation
D. paternal mitochondrial leakage
Homework Answers
What phenomenon is this an example of?
In order to control the expression of all of the genes of the X chromosomal charge, the Caenorhabditis elegans undergoes a process called dosage compensation to inactivate one X chromosome

19) Trisomy 21, or Down syndrome, occurs when there is a nom complement but one (extra) chromosome 21. Although fertility is reduced in both sexes, females have higher fertility rates than males. Van Dyke et al. (1995; Down Syndrome Research and Practice 3(2):65-69) summarize data involving children born of Down syndrome individuals. Assume that children are born to a female with Down syndrome and a normal 46-chromosome male. What proportion of the offspring would be expected to have Down syndrome?...

A genetically engineered plasmid Ficarries all of the elements of the lac operon, but replaces the structural genes with the reporter gene green fluorescent protein (GFP). The repressor allele cannot bind lactose, and the OC allele cannot be bound by the repressor. Given the following genotypes and growth media that does not contain glucose, indicate in the table below whether you expect to see b-galactosidase activity and glowing green colonies of E. coli by selecting Yes or No. growth media...
