No links! The savanna is home to a variety of plant and animal species. Populations depend on and may compete for biotic and abiotic factors in this biome. Select ALL of the interactions between biotic factors in the savanna. A)A pride of lions hunt zebra.
B)The yearly rainfall pattern causes wet and dry seasons.
C)Populations compete for food sources at the watering hole.
D)The average rainfall and temperature determine the plant life that can grow in the savanna.
E)Herbivores such as elephants and rhinos depend on the variety of grasses that grow in the savanna.

A

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
