In rats, gene b produces black coat color if the genotype is b-, but black pigment is not produced if the genotype is bb. at an independent locus, gene d produces yellow pigment if the genotype is d-, but no pigment is produced when the genotype is dd. production of both pigments results in brown coat color. if neither pigment is produced, coat color is cream. a third independently assorting gene involved in determination of coat color in rats is the c gene. at this locus, the genotype c- permits expression of pigment from genes b and d. the cc genotype, however, prevents expression of coat color and results in albino rats. for each of the following crosses, determine the expected phenotypes and their ratio in progeny:

part a
bbddcc x bbddcc
express your answer as five numbers separated by colons. if there is no progeny of a particular phenotype, enter zero (black: brown: yellow: cream: albino).

part b
bbddcc x bbddcc
express your answer as five numbers separated by colons. if there is no progeny of a particular phenotype, enter zero (black: brown: yellow: cream: albino).

part c

eukarya because is is like alche and b is bacteria and d is animals

it should be briana that has it to me

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.

the atomic number of magnesium is 12. its nucleus must contain 12 protons and no electrons. the atomic number of an atom is determined by the number of protons.

magnesium is an electrolyte injection commonly used to treat low magnesium levels in your blood. it is also used to prevent or control seizures in women with preeclampsia or eclampsia.
