Question
In Drosophila, females heterozygous for the recessive alleles m, q, and z were crossed to males homozygous recessive for these three mutant genes. The phenotypes of the resulting progeny were: The gene order is known to be mqz. How many map units separate genes q and z? a) 8 b) 10 c) 15 d) 28 e) 30 The gene order is known to be mqz. How many map units separate genes m and q? a) 8 b) 10 c)15 d) 28 e) 30 Given the wobble hypothesis, if CCU codes for proline, UUC codes for phenylalanine, and CGU codes for leucine, then it is most likely that CCA codes for: a) serine b) threonine c) proline d) phenylalanine e) leucine When n equals ABC, AAABBBCCC is: a) diploid b) triploid c) monosomie d) trisomie e) monoploid How many Barr bodies are present in a 47, XXY male? a) none b) 1 c) 2 d) 3 e) 4Explanation / Answer
