get a roan or mixed calf, but a black one like its father. 
Certain colors, such as black and white, seem to be more 
persistent, more powerful than other colors; these colors 
are said to be “dominant” over the others. On the other 
hand, animal and plant breeders can often take two very 
unlike parents and obtain offspring which are perfect

rabbits and short-eared rabbits, a learned professor found 
that the baby rabbit’s ears were neither long nor short, 
but halfway between. Many plant hybrids (children of 
parents of different plants) are very exact blends of 
their parents. The natural color of a wild rabbit is grey. 
If the breeder crosses two tame rabbits, a black father 
rabbit and a white mother rabbit, he will soon have a 
little baby rabbit the color of its faraway wild grey an¬ 
cestor. Living creatures will always return to their 
wild state if they have a chance, and this baby rabbit had

It is the nucleus of the cell that carries red hair or 
lop-ears or white fur or long chins from generation to

the egg-cell of the white rabbit, it was decided then and 
there what color fur the baby rabbit would have. When 
after fertilization the egg-cell grows and divides, the
