In 1910, Morgan did a series of experiments with the fruit fly Drosophila, an organism where females are XX and males are XY. Wh

en a mutant male fly with white eyes was crossed with a wild-type female with red eyes, none of the F1 progeny had white eyes but 18% of the F2 flies had white eyes. Unexpectedly, all of these white-eyed F2 flies were males. From these results, Morgan concluded that the white eye trait is caused by a recessive allele located on the X chromosome. Instead of fruit flies, suppose Morgan had done his experiments with grasshoppers, where females are XX and males are XO. In this case, if a male with a recessive X-linked trait was crossed with a wild-type female, what would you expect among the F2 progeny?

Select all that apply.
andriy [413]

The <em>correct</em> answer is:

Penicillium

Aspergillus

The lesson states:

If you've ever heard of or taken penicillin to fight off an infection, you can thank a member of the imperfect fungi called penicillium. Some mold species of penicillium are also important in the flavoring and aging of cheese. Roquefort and Camembert cheese owe their distinctive flavors to these fungi. Aspergillus is an imperfect fungus that is found on decaying food. It also contributes to the production of organic acids like citric acid. <u>Both penicillium and aspergillus produce enzymes that are purified and used in various industrial compounds and in medicine.</u>
