Two Different Genes Are Required For Proper Embryo Development Mutations In Gene 1 M Are Recessive Maternal Effect L 1 (36.61 KiB) Viewed 214 times

Two different genes are required for proper embryo development. Mutations in gene #1 (m) are recessive maternal-effect lethal. Mutations in gene #2 (t) are recessive lethal due to zygotic transcription. From the crosses below, indicate what % of offspring are viable (become adults) and the genotype of the viable offspring. If no offspring is viable, leave the genotype column blank for that specific cross. male parent x female parent % viable offspring genotype of viable offspring M/m M/m T/t T/t M/M m/m T/t; m/m T/t; M;M You have identified 5 complementation groups for genes involved in drosophila leg development. One mutant allele has a dominant phenotype and remains un- grouped. How can you determine if the dominant mutant is an allele of one of the 5 complementation groups or a new complementation group using a genetic cross? Assume the fly with the dominant allele is heterozygous.
