Corn kernels have an outer endosperm and an inner endosperm. a purple outer endosperm is dominant to a
colorless (clear) outer endosperm. a yellow inner endosperm is dominant to a white inner endosperm. the inner
endosperm color is not seen if the outer endosperm color is the dominant form. if the outer color is recessive
or suppressed, the inner color is visible.
the genetic codes are as follows:
r = purple outer endosperm
r = colorless outer endosperm
y = yellow inner endosperm
y = white inner endosperm
c = dominant color suppressor c= no dominant color suppressor
a. what is the pattern of inheritance for corn kernel color?
a. autosomal mendelian
b. x-linked
c. codominance
d. incomplete dominance
e. polygenic
f. epistasis

Keeping in mind the life cycle of bacteriophages, consider the following problem: during the reproductive cycle of a temperate bacteriophage, the viral dna inserts into the bacterial chromosome where the resultant prophage behaves much like a trojan horse. it can remain quiescent, or it can become lytic and initiate a burst of progeny viruses. several operons maintain the prophage state by interacting with a repressor that keeps the lytic cycle in check. insults (ultraviolet light, for example) to the bacterial cell lead to a partial breakdown of the repressor, which in turn causes the production of enzymes involved in the lytic cycle. as stated in this simple form, would you consider this system of regulation to be operating under positive or negative control?

Drag each description to the correct location on the image. not all descriptions will be used. describe the parts of a comet. the frozen part of the comet the atmosphere of gases and dust formed when the nucleus vaporizes tail made of small, solid dust particles tail made of ions that appears to point away from the comet's orbit
