A certain (hypothetical) organism is diploid, has either blue or orange wings as the consequence of one of its genes, and has either long or short antennae as the result of a second gene. A female with a paternal set of one orange and one long gene chromosomes and a maternal set comprised of one blue and one short gene chromosome is expected to produce what types of eggs after meiosis?

Meiosis reduces chromosome number and rearranges genetic information. a. Explain how the reduction and rearrangement are accomplished in meiosis. b. Several human disorders occur as a result of defects in the meiotic process. Identify one such chromosomal abnormality, and describe how and error in meiosis causes it. What effects does it have on the phenotype of people with the disorder?
