Deducing a Genotype: If assuming PTC as a simple gene trait, what other genotype would you select to put in this missing genotype box that could result in this phenotype? Why?

Tt

Explanation:

It would be Tt because it has to have a dominant allele to be considered a taster.

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
