Three enzymes are part of a sequential pathway that produces a pigment that makes flowers red.  Each enzyme is the gene product of a different locus. If a trihybrid, heterozygous (+/-) for each of the three loci, is selfed, what fraction of the offspring will not be able to produce the red pigment (and will thus have white flowers)? Express your answer as a number between 0 and 1, rounding to 2 decimal places.  For example, if you think 1/4 of the offspring will have white flowers, then answer 0.25

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
