Answer:
species richness is the number of species in an ecosystem
Since between the two alleles (B for black and b for white) there is an incomplete dominance this means that the homozygotes for the one dominant trait (BB genotype) will be black, the homozygotes for the other trait (bb) will be white, and the heterozygotes (Bb) would be intermediate- grey.
So, the two grey lizards have the Bb genotypes.
When they cross we will get Bb x Bb
1 : BB ( black lizards)
2: Bb ( grey lizards)
1: bb ( white lizards)
The average speed of a zebra is 40mph or 64km.
