Answer:
In species with polyploid, there are more chromosomal sets than in diploid one. Becouse there are more chromosomal structures available, events like mutation, recombination, DNA lose, are more probable to occur.
As the generations pass, the accumulation of these changes tend polyploid to speciation.
Answer:
One-half of the daughters of an affected man would have this condition.
Explanation:
Each daughter born to a woman that is positive for a dystrophin mutation on one of her two X chromosomes possess a 50 percent likelihood of possessing the mutation and also becoming a carrier. Carriers at times do not show the disease symptoms but may give birth to a child that has the mutation or the disease condition. DMD carriers do have a higher chance of cardiomyopathy.
A man with DMD cannot transfer the affected gene to his sons since he passes to his son a Y chromosome, not the X chromosome. But he will definately transfer it to his daughters, since each daughter possess her father’s only X chromosome resulting in the daughters being carriers.
Hence, One-half of the daughters of an affected father and a carrier mother could have this condition.

I think Number C is right because Since the organism eukaryotic we can safely assume that it is neither an archaea nor a bacteria since they are both prokaryotes. Secondly, since it can not photosynthesize, it can't be a plant because all plants can photosynthesize. The presence of a cell wall tells us that it can't be an animal cell since they lack cell walls. Therefore, the organism found is a fungus-like protist. Fungi are prokaryotic cells that are unable to photosynthesize and they have cell walls.
