Imagine a species whose eye color is determined by a receptor molecule called EyeC. When EyeC is not activated, CAMP levels in the cell are low and yellow pigment is produced. When EyeC is activated by the binding of a signal molecule, CAMP levels rise and blue pigment is produced. The Q allele codes for a version of EyeC that responds to signal molecules and therefore turns on and off, resulting in green eye color (from both blue and yellow pigment). The P allele codes for a version of EyeC that is ALWAYS activated, even when signal molecules are not present. Assuming EyeC functions similarly to MCIR, which of the following statements is the best prediction of the dominance relationship between alleles P and Q as well as the phenotype for PO individuals? 1. Q is dominant over P, and the eye color of PQ individuals is blue.
2. Q is dominant over P, and the eye color of PQ individuals is yellow.
3. Pis dominant over Q, and the eye color of PQ individuals is blue.
4. Pand Q are codominant, and the eye color of PQ individuals is green.

Will mark brainliest! 1.) jan’s sister and mother have both had breast cancer. she is wondering if she should undergo genetic testing to check for a mutation of the brca1 gene. a mutation in the brca1 gene is commonly associated with, but not guaranteed to cause, breast cancer. the presence of a mutation increases a patient’s chances of getting breast cancer to about 85 percent, compared to a 13 percent risk in the general population. costs may vary, but most labs charge patients or their insurance companies less than $3,000 to sequence the brca1 to look for mutations. do you think that jan should undergo genetic sequencing? explain your answer. (2 points) what are potential pros and cons of having such tests done? (5 points) describe how the availability of genetic sequencing can affect the frequency of genetic diseases in individuals and populations. (3 points) 2.) scientists have developed genetically engineered plants that are pest-resistant. by adding genes to the plant’s dna, they become toxic to insects (but not to plants or animals). this means that these plants may not need to be sprayed with pesticides to ward off the insects. would you be willing to eat these genetically altered crops? explain your answer. (5 points) what are some possible impacts (positive or negative) of this genetically engineered plant on the environment, society, and individuals? (5 points)
