1 A farmer has rabbits with two particular traits, each controlled by a separate gene.
Coat colour brown is completely dominant
to white. Tailed is completely dominant to
tail-less. A brown, tailed male rabbit that is
heterozygous at both loci is crossed with a
white, tail-less female rabbit. A large number
of offspring is produced with only two
phenotypes: brown and tailed, white and tail-
less, and the two types are in equal numbers.
(i) State both parents' genotypes and the
gametes that are produced by each during
the
process of meiosis.

(ii) Predict the genotypic and phenotypic ratios
of the F, generation. Show your working.

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.
