The kernel color in wheat is a continuous trait determined by two additive genes, each with two alleles, that equally contribute to kernel color determination. the red kernels are determined by two genes and two dominant alleles (r1r1r2r2), and white kernels are determined by two recessive alleles at the same two genes (r1r1r2r2). the duplicate dominant alleles r1 and r2 contribute equally to kernel color and cumulatively control the intensity of the red kernel phenotype. both these alleles are dominant over the recessive white alleles r1 and r2. a true breeding red plant and true breeding white plant are crossed, and the resulting f1 progeny are selfed. what is the expected phenotypic ratio of the kernel progeny of the f2 offspring?

Protein and polypeptide sequences can be determined by first partially hydrolyzing the protein or polypeptide followed by amino acid sequencing of the fragment pieces using the chemical degradation process known as edman degradation. determine the sequence of the initial (18-amino acid) polypeptide that produces the following five partial sequences after hydrolysis and edman degradation.
