Mouse coat color genes pdf
molecular, cellular, and genetic basis for mouse coat colour. In the review activities for modules 1 and 2, we learned about a protein called MC1R that is found in the cell membranes of specific mouse cells called melanocytes, whose job it is to produce the pigment melanin, which gives mice the colouration of their fur.In this activity we will further examine the genetic and molecular basis
A classic example is the yellow coat color allele in mice. Mice that are heterozygous for this allele have yellow fur, but mice that are homozygous are dead. (a) Is the yellow allele dominant or recessive for yellow fur? Is the yellow allele dominant or recessive for lethality? (b) Given a yellow mouse and a wild-type mouse how would you show that the allele for the yellow trait is dominant

Two closely linked genes in the mouse. H. Grüneberg (a1) and G. M. Truslove (a1) Ph has no detectable effect on the coat colour, but in the double heterozygote with W v, it slightly increases the dilution effect of the latter in the regions which remain pigmented. Similarly, Ph by itself has no appreciable effect on the red-blood picture of 13–14-day-old animals, but in the double
Summary. Embryos heterozygous for five recessive coat-color genes from the cross C 57 BL/6 J Han x T-stock were X-irradiated with 100 r or treated in utero with 50 mg/kg methyl methanesulfonate (MMS) and ethyl methanesulfonate (EMS), respectively.
