Solved by a verified expert:Corn Kernel Genotypes and Phenotypes
A) While examining an ear of corn, you notice that the
kernels in the ear display two apparent phenotypes; yellow and white. inspired
by your understanding that these represent different alleles of a single gene,
you count the kernels of each type and you asses 347 yellow (Y) kernels and 111
white (y) kernels. if this ear of corn is an F2 hybrid, what was the genotype
of its F1 parent? which allele is dominant?
b) For the ear of corn detailed above, test to see if the
observed phenotype distribution fits the predictions of the genotype using the
X2 test. what is your hypothesis? do the data permit you to accept the
hypothesis? show work.
