gray fur is heterozygous dominant for mice & two gray mice are crossed to produce offspring ->  two heterozygous dominant mice are crossed to produce offspring  two heterozygous dominant mice are crossed to produce offspring & if a heterozygous dominant organism is crossed / bred with a heterozygous dominant organism , then the offspring will have a 25% probability of being homozygous recessive ->  the offspring will have 25% probability to be homozygous recessive  the offspring will have 25% probability to be homozygous recessive & white fur is homozygous recessive for mice ->  the offspring will have 25% probability to have white fur  two heterozygous dominant mice are crossed to produce offspring & if a heterozygous dominant organism is crossed / bred with a heterozygous dominant organism , then the offspring will have a 25% probability of being homozygous dominant ->  the offspring will have 25% probability to be homozygous dominant  the offspring will have 25% probability to be homozygous dominant & black fur is homozygous dominant for mice ->  the offspring will have 25% probability to have black fur  two heterozygous dominant mice are crossed to produce offspring & if a heterozygous dominant organism is crossed / bred with a heterozygous dominant organism , then the offspring will have a 50% probability of being heterozygous dominant ->  the offspring will have 50% probability of being heterozygous dominant  the offspring will have 50% probability of being heterozygous dominant & gray fur is heterozygous dominant for mice ->  the offspring will have 50% probability to have gray fur  the offspring will have 25% probability to have white fur & the offspring will have 25% probability to have black fur & the offspring will have 50% probability to have gray fur -> the offspring will have 25% probability to have white fur, 25% to have black fur, and 50% to have gray fur
