A new mutation is discovered in fruit flies, one in which the flies have two pairs of wings instead of one. Two double pair flies are mated. Their offspring consist of 20 double pair flies and 10 single pair flies (i.e. wildtype). What is a likely explanation for this outcome? Group of answer choices the results make no sense and further investigation is needed double wing is a recessive lethal double wing shows incomplete dominance double wing shows complete dominance

You want to determine whether short wings in fruit flies are the result of a dominant or recessive mutation. You cross a short-winged fly stock with a long-winged fly stock (which is considered to be wild type or / ). The progeny have a 1:1 ratio of short to long wings. You then allow the F1 short-winged flies to mate. The F2 progeny have a phenotypic ratio of 3:1 short to long wings. Short wings are likely the result of:

You are trying to determine the mode of inheritance for the mutant curly-winged phenotype in Drosophila. You cross pure-bred wild-type flies with pure-bred mutant (curly-winged) flies and notice that all of F1 has curly wings. You make the scientific hypothesis that the curly-winged phenotype is autosomal dominant to the wild-type wing phenotype. a. If your scientific hypothesis is correct, what ratios would you expect to see in your F2 generation?

The miniature wing gene in Drosophila is on the X chromosome. It is recessive. Normal sized wings (wild type) is completely dominant over miniature wings. A HETEROZYGOUS normal winged female is mated to a wild type male. What would be the phenotypes of the offspring?
