When calvin bridges observed a large number of offspring from a cross of white-eyed female drosophila to red-eyed males, he observed very rare white-eyed females and red-eyed males among the offspring. he was able to show that these exceptions resulted from nondisjunction, such that the white-eyed females had received two xs from the egg and a y from the sperm, while the red-eyed males had received no sex chromosome from the egg and an x from the sperm. what progeny would have arisen from these same kinds of non-disjunctional events if they had occurred in the male parent? what would their eye colors have been?

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

e) all of the above

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
