# What are the expected phenotypes from this pairing? (Sex-influenced Punnet Square)?

It turns out there is life on Mars, and genetics works the same way there. Tooth color is a sex-influenced trait in Martian rodents. Wild-type teeth are purple, and mutant teeth are green. The green allele is dominant in females and recessive in males. You have 2 rodents, a purple toothed male whose mother had green teeth, and a green-toothed female whose father had purple teeth. You mate them together. Calculate the probability that: offspring would have purple teeth offspring will be male, green teeth offspring would be female, green teeth I got 3/8, 2/8, 3/8 and I'm not sure if it's right. Thanks for the help in advance. 4/8, 2/8, and 2/8 wasn't the answer sadly. Here's the hint it gave me, hint: figure out the genotypes of the parents first. then write out the results of a cross between them, looking only at tooth color. then recall that for every baby rodent there is 1/2 chance it will be male and a 1/2 chance it will be female. finally, determine the phenotype for all offspring, male and female. Glad I wasn't the one that was confused by the question though. only one* I tried out the question again, and I think you were right how 75% F would have green, and 75% M would have purple. It seems to be 4/8, 1/8, 3/8, because the fractions are representative of a male and female individual in each Punnet square. There's definitely a poorly worded question in this assignment, but this question was done in class with another example so I think I was just thinking about it wrong. Thanks for trying to help!
