Drosophila eye color is an x-linked trait. red eye color is dominant, and white eye color is recessive. which punnett square shows the probability that 25 percent of offspring will be red-eyed males?

Second Punnett on the first attachment.

Explanation:

In a 4 x 4 Punnett there are a total of 4 squares. Twenty five percent (25%) of 4 is 1. This means that only 1 square out of the 4 should have the genotype that you are looking for.

Okay going at it in a biological sense. Because red eyes is dominant, we know that the allele should be represented by a capital R. It is X-linked, so it should be on the X. The problem is looking for the probability of a male offspring so the combination should be XY (this means the offspring is male, XX is for females).

So taking that all together, you're looking for the genotype combination:

So you need to find the Punnett that has only 1 square with this combination. The attachment shows which specific Punnett:

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
