In foxes, silver-black coat colour is governed by a recessive allele b and red coat color by its dominant allele (B). Determine the genotypic and phenotypic ratios expected from the following matings: a. Pure red x carrier red b. Carrier red x silver black c. Pure red x silver-black

multiplying and dividing the two decimals and the eqations by the same number of the overalls

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
