Answer :
Final answer:
If a strain is homozygous for all dominant markers on chromosome 9, the kernel phenotype would show traits corresponding to the dominant alleles, resulting in colored and smooth kernels assuming these are the traits conferred by the dominant alleles on the chromosome.
Explanation:
If the strain were homozygous for all dominant markers on chromosome 9, the kernel phenotype would express the traits associated with the dominant alleles for those markers. For example, if we consider dominant alleles that are responsible for kernel color and texture, the phenotypic value would manifest as kernels that are colored and of a texture that is specified by the dominant allele. In cases of complete dominance, such as the examples given, the phenotype of the homozygous dominant organisms would show no signs of the recessive traits.
Based on the provided information, if the organism has phenotypes that include color and smoothness, and those are known to be dominant over colorlessness and shrunken endosperm (as indicated in the information on kernels produced being yellow and smooth), we can expect the kernels of a homozygous dominant strain to be colored (due to dominant allele and smooth (due to dominant allele Sh).
