Question

Below is a table showing the results of complementation analysis of 10 wing mutant strains (w1-w10) of fruit flies isolated in the lab. Each mutant strain is unable to produce wings. In the complementation analysis, each strain is crossed to all of the other strains and the ability to produce wings in the offspring is assessed. If the offspring had wings the box is denoted with a "+" (eg. w1 crossed to w5 produces winged progeny) while if the offspring that did not have wings it is denoted with a "-" (eg. w1 crossed to w2 produces wingless progeny. W1 W2 W3 W4 W5 W6 W8 W9 w10 W1 W2 W3 W4 W5 W6 W7 W8 w10

Explanation / Answer

1.

a. The answer is W2

b. the answer is complementation, which is known as a homozygous recessive mutation will produce the same phenotype, which when mated or crossed again will produce the wild type phenotype.
