Question

Hemophilic 1 2 3 7.32 The following pedigree, described in 1938 by B. Rath, shows the inheritance of X-linked color blindness and hemophilia in a family. What are the possible genotypes of II-1? For each possible genotype, evaluate the children of II-1 for evidence of recombination between the color blindness and hemophilia genes. Genomics on the Web at http://ww Chromosome maps were first developed by T. H. Morgan and this students, who used Drosophila as an experimental organism. 1. Find the woman

Answer 1

Any # Colour blindness is an X-linked recessine diseases. Meaning: If a female ham xxc , then the female is not colour-blind but is a carrier. so for female : XX normal x xo y carrier X x Colour-blind xe means affected gene for male : . X Y normal XCY there is no case Colour-blind of carrier for male. recessive disorder. # Haemophilia is also an X-linked so, similarly, for female XX normal x xh carrin amophilic xhxh colon blond how ; xh means affected gen for male X Y normal Xhy that haemophilic
