In the region of chromosome 15 that is deleted in both Prader-Willi and Angelman syndrome, there are a number of different genes, some encoding proteins and others non-coding, meaning that they produce RNA but not protein. There is also an imprinting center, which affects expression of several nearby genes. This imprinting center is maternally imprinted. Which of the following statements are true? (select two answers) a. The DNA in the imprinting center is methylated during sperm development and escapes reset during early development.
b. The DNA in the imprinting center is methylated during egg development and escapes reset during early development.
c. The imprinting center has DNA methylation on the maternal chromosome.
d. The imprinting center has DNA methylation on the paternal chromosome.

Aneuron is stimulated with an electric pulse. the action potential is detected at a point 3.70 cm down the axon 0.0052 s later. when the action potential is detected 7.20 cm from the point of stimulation, the time required is 0.0063 s. what is the speed of the electric pulse along the axon? (why are two measurements needed instead of only one? )

In sweet pea, gene c is responsible for color production and gene p is responsible for the purple color pigment. both of them are located on two different loci on different chromosomes. the flowers will be purple only when the plant has the genotypes as c_p_. no color will be produced with genotypes: ccpp, ccpp, ccpp, ccpp. thus, gene c controls the expression of gene p. what pattern of inheritance is exhibited here? a. pleiotropy b. epistasis c. multiple alleles
