Based on the pedigree that is shown above, how to describe Fred?

The given pedigree analysis shows sex-linked trait where the female work as a carrier and have X linked recessive gene that is and the male is normal.

So, Fred will be a male with gene and Fred will be affected with X linked disease which is carried by female.

If,   gene in the female (Ann)  act as a carrier of hemophilia and the male (John) is normal, then Fred will be a male affected with hemophilia (sex linked disease).

Hence, Fred will be affected male with   genotype.

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.
