Assume that x is a new mutant allele in corn.An x/x plant is crossed with a triple-10 individual (trisomic for chromosome 10)carrying only normal dominant alleles at the x locus.Trisomic progeny for chromosome 10 are recovered and crossed back to x/x.
a)What ratio of dominant to recessive phenotypes is expected if the x locus is not in chromosome 10?
b)What ratio of dominant to recessive phenotypes is expected if the x locus is in chromosome 10?

The Answer of Assume that x is a new mutant allele in corn.An x/x plant is crossed with a triple-10 individual (trisomic for chromosome 10)carrying only normal dominant alleles at the x locus.Trisomic progeny for chromosome 10 are recovered and crossed back to x/x.
a)What ratio of dominant to recessive phenotypes is expected if the x locus is not in chromosome 10?
b)What ratio of dominant to recessive phenotypes is expected if the x locus is in chromosome 10?
