determine how many phenotypes can be produced in offspring?

probability of having offspring with the aabb genotype: 1/16

Explanation:

The  cross  of  heterozygous  AaBb as  parental  phenotype led   to  formation  of  16  phenotype   of  the  offspring.This  is  because  this  is  dihybrid   form  of inheritance .The   probability  of  having  aabb   offspring  is  1/16  since   there  is  only  one  aabb  type  of  offspring  phenotype  out  of  the  16.  

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.
