Let us denote black fur as the dominant fur color, and grey fur as the recessive fur color. So, homozygous for black fur will be BB, and grey fur bb.
Let us denote long claws as dominant, and short claws as recessive. So, heterozygous for long claws will be Ll, and homozygous long claws will LL.
The percentage will be 100%, none of the individuals is homozygous recessive. If both of them were heterozygous dominant, then 25% of the offspring would be homozygous recessive.
