Four eye-color mutants in Drosophila—apricot, brown, carnation, and purple—are inherited as recessive traits. Red is the dominant wild-type color of fruit-fly eyes. Eight crosses (A through H) are made between parents from pure-breeding lines. Predict F₂ phenotype ratios of crosses A, B, D, and G. <>

Hello, everyone. Here we have a question asking which of the following is true about why linked traits in Drosophila. A while linked traits are always dominant. B while linked traits can be inherited by both males and females. See, while linked traits are relatively rare in Drosophila or d while linked traits are always lethal. Let's circle back to a while linked traits are always dominant. This is not true. They can also be recessive. B while linked traits can be inherited by both males and females. This isn't true. They can only be inherited by males. See, while linked traits are relatively rare in Joseph, Sheila. This is true and this is because the Y chromosome is much smaller than the X chromosome and carries fewer genes. So C is true, the wiling traits are always lethal. This is false. They don't always have to be lethal. So our answer here is c while linked traits are relatively rare. Interests of Villa. Thank you for watching. Bye.
