Waltzing mice is recessive to running mice. If two waltzing mice mate what is the chance their offspring will be running?

well if R is running and r is waltzing...and 2 waltzing parents are crossed rrxrr...all the offspring will be rr and hence waltzing...so the chace of running mice is 0!

Just a comment for Majik_8_ball's answer--if the dominant allele is running and the recessive allele is waltzing, and both mice waltz, then all the offspring will waltz and none have a chance of running. This is true because the mouse will only waltz if it has TWO recessive alleles.

No chance. Since both mice are carrying the recessive gene, there is no dominant gene to express the running.
Unless running is some common mutation of waltzing.

If both parent are heterozygous, each child has a 75% chance of having the dominant phenotype and a 25% chance of having the recessive phenotype.

One in Four, if they were running mice carrying the waltzing mice gene.
