White eyes in drosophila melanogaster result from an x‑linked recessive mutation. occasionally, white‑eyed mutants give rise to offspring that possess white eyes with small red spots. the number, distribution, and size of the red spots are variable. explain how a transposable element, or transposon, could be responsible for this spotting phenomenon. excision of a transposable element out of the eye color locus during eye development produces a patch of cells that produce red pigment. a transposable element is introduced into the regulatory region of the eye color gene and causes gene expression to be reduced, which results in white eyes with red spots. insertion of a transposon upstream of the eye color locus during eye development activates the red pigment production gene in a patch of eye cells. a transposon located within the eye color gene uses reverse transcriptase to produce the normal gene product, which causes white eyes with red spots. transposable elements insert into the eye color locus in the majority of the eye cells, leaving only a patch of eye cells with an active eye color locus that produces red pigment.

You perform a backcrossing experiment to map regions of the corn genome that responsible for kernel size. first, you cross true breeding plants with large kernels to true breeding plants with small kernels. the f1 hybrids have medium size kernels. you then backcross the f1 to the parents with small kernels, and you genotype the backcross progeny at 100 marker loci. you observe that progeny that are heterozygous at locus 1 have larger kernels than individuals that are homozygous at locus 1. in contrast, individuals that are heterozygous at locus 2 have the same size kernels as individuals that are homozygous at locus 2. which of the following statements is most consistent with your results? a) both loci 1 and 2 are in linkage disequilibrium with genes that affects kernel size.b) neither locus 1 or 2 is in linkage disequilibrium with a gene that affects kernel size.c) locus 2 is in linkage disequilibrium with a gene that affects kernel size.d) locus 1 is in linkage disequilibrium with a gene that affects kernel size.
