Parents Black with vestigal wings b bvg vg Wild Type (gray with normal wings) Black. GrayBlack wild Type Vestigial Vestigiat Normal Offspring Expected Parental phenotypesRecombinant phenotypes Observed 965 206 185 944 o The gene for body color and wing type are located on different chromosomes The gone for body color and wing type are located very close on the same chromonome The gone for body color and wing type are located tar apart on the same chromosome The genes for body color and wing type assort independently Cannot be determined foren the ieformatlon provided

Explanation / Answer

Answer:

The genes for body color and wing type are very close on the same chromosome

Explanation:

According to Mendel's dihybrid testcross ratio, the resultant phenotypes should be in 1:1:1:1 ratio when the genes assort independently.

The observed phenotype number are deviated from the above testcross ratio. It means that the genes are linked and present on the same chromosome.
