Loppins Are Fictitious (But Useful)diploid Invertebrates That Produce Large Offspring

question 1

Essay

Loppins are fictitious (but useful)diploid invertebrates that produce large offspring and normally have long antennae.Short antennae mutants also exist.Unfortunately for the geneticists working on these organisms,the males' antennae don't fully develop until the loppin equivalence of "middle age." A female with short antennae is crossed to a young male,and all the females in their offspring have the short antennae mutant phenotype.A subset of these F₁ females are crossed to a middle-aged male with short antennae,and all the females produced by these crosses have short antennae.However,all the crosses between the F₁ females and their brothers produce both short antennae and long antennae loppins in a ratio of about 3:1.How can these results be explained? Provide the genotypes of as many individuals as possible.
