Answer: Draw a deflected shape of a continuous beam(two spans with a cantilever portion) under a uniform load and show the locations of main reinforcement
A polygenic trait is controlled by three pairs of alleles. What are the two extreme genotypes for this trait?

A polygenic trait is controlled by three pairs of alleles . Human skin colour is controlled by several gene pairs . Let us assume here that there are just three gene pairs on different chromosomes and that for each pair there are two alleles an incompletely dominant one that codes for melanin deposition.

Polygenic inheritance differs from multiple alleles as in multiple alleles three or more alleles are present in the same locus of which any two alleles are present in an organism e.g. ABO blood group system which is controlled by three alleles ; There is no epistasis involved i.e. masking of the expression of an allele of the different locus. A polygenic trait is one whose phenotype is influenced by more than one gene. ...
