1. In silkworms, a PURPLE cocoon is dominant over a BLUE cocoon. Cross a homozygous purple silkworm with a homozygous blue. List genotypes and phenotypes. 2. In guinea pigs, short fur is dominant over long fur. Cross a heterozygous female with a homozygous long furry male. List genotypes and phenotypes.

3.In race horses, black coat (B) and trotting gait (T) are dominant traits. Recessive traits are chestnut coat (b) and pacing gait (t). Use a Punnett square to determine the possible offspring from a cross between a heterozygous black coat trotter and one that is homozygous for black coat and is a pacer. List genotype and phenotype ratios.

4.In pea plants, a YELLOW (Y) color is dominant over PURPLE (y) and SMOOTH (S) is dominant over WRINKLED (s). Use a Punnett square to determine the F2 generation from a cross between a homozygous yellow smooth pea and a heterozygous yellow smooth pea. List the genotype and phenotype ratios.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.

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.
