Recessive maternal effect genes are identified in flies (for example)when a phenotypically normal mother cannot produce any normaloffspring. Because all of the offspring are dead, this female fly cannot be used to produce a strain of heterozygous flies that could beused in future studies. How would you identify heterozygous individuals that are carrying a recessive maternal effect allele? Howwould you maintain this strain of flies in a laboratory over manygenerations?

Question

Recessive maternal effect genes are identified in flies (for example)
when a phenotypically normal mother cannot produce any normal
offspring. Because all of the offspring are dead, this female fly cannot be used to produce a strain of heterozygous flies that could be
used in future studies. How would you identify heterozygous individuals that are carrying a recessive maternal effect allele? How
would you maintain this strain of flies in a laboratory over many
generations?
