WebThere are two types of mapping – Genetic Mapping and Physical Mapping. Genetic Mapping. Genetic Mapping is used to find out the relative position of genes in a chromosome. It uses recombination and linkage studies to find out the relative distance and inheritance pattern. The mapping begins by collecting specimens from close relatives … WebShe wants to determine whether the gene encoding the quiver phenotype is linked to the recessive gene encoding vestigial (reduced) wings $(v g) .$ She crosses a fly homozygous for quiver and vestigial traits with a fly homozygous for the wild-type traits and then uses the resulting $\mathrm{F}_{1}$ females in a testcross.
