In humans muscular dystrophy (m. d.) is caused by a recessive allele on the X chromosome. Draw a punnett square to show how two unaffected people can have a child with muscular
dystrophy.
a. Genotypic ratio
b. Phenotypic ratio
e. Is the child with muscular dystrophy a male or a female?
d. What's the probability that their next child will have m. d.?
e. What percentage of the male children will have m. d.?
f. What percentage of the female children will have m. d.?

this protocol provides a detailed procedure for chromatin immunoprecipitation (chip) to study the dna-protein interactions.

lesson summarykaryotypes a genome is the full set of all the genetic information that an organism carries in its dna. chromosomes arebundles of dna and protein found in the nucleus of a eukaryotic cell.

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.
