Spotted angora - 26
Solid coloured angora 144
Spotted short hair 157
Solid colour short hair 23

A wild plant with genes AABBCC was crossed with a triple recessive mutant aabbcc. The F1 male hybrid (AaBbCc) was then back crossed with the triple mutant and the phenotypes recorded are as follows
AabbCc (50), aaBbcc(50), AaBbCc (100), aabbcc (100), AaBbcc (350), aabbCc (350)
Distance between A to B is ----------M----- map unit with ………N…….configuration, distance between B to C is ----O---- map unit with ------P-------configuration?

#Unit 8. Inheritance Biology
A panel of cell lines was created from mouse–human somatic-cell fusions. Each line was examined for the presence of human chromosomes and for the production of three enzymes. The following results were obtained On the basis of above results. Which of the following chromosome location of enzyme 1, enzyme 2, and enzyme 3?

In Drosophila melanogaster, cinnabar eye (cn)and vestigial wing (vg) are simple recessive traits.a A male pure line wild type eye ,vestigial wing cross with female pure line cinnabar eye, wild type wing . F1female, heterozygous for both genes, was crossed with a male with cinnabar eyes and vestigial wings. The offspring resulting from this cross are listed in below class
I Wild type
II Cinnabar eye, wild-type wing
III Wild-type eye, vestigial wing
IV Cinnabar eye, vestigial wing
Above class are recombinant progeny
