Question

6. There are many eye color mutants in Drosophila. The table below shows the outcome of crosses between different homozygous mutant strains, a “+" indicate that offspring had wild type eye color, a""indicates that they had a mutant eye color. How many different genes are represented in the table? Mutation Apricot Brown Buff Carnation Cherry Claret Coral Vermilion White Apricot - Brown Buff Carnation Cherry Claret Coral Vermilion White a) two b) three c)four d) fivee) there isn't enough information to tell

Explanation / Answer

Here Four genes are present.

Option c is correct.

when any of the mutant gene is matched with the any of the four gene ( gene responsible for color carnation, claret, brown and vermilion) then the wild type of springs are produced. So we can say that Four genes are important which can complement any mutant phenotype.

these four genes are responsible for wild type phenotype.

You can see here, when these four coloured mutant are mixed with onother mutant than normal phenotype are observed.

That is why four genes are involved.
