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.

What do we call an individual that has inherited two identical alleles for the same trait? a.homozygous b.heterozygous c.monozzygous

During crossing-over, a. genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles. b. nonsister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles. c. one homologous chromosome of a tetrad is exchanged with another tetrad, resulting in new combinations of alleles. d. sister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles. e. genetic material is exchanged between sister chromatids, resulting in new combinations of alleles.
