Whales are related back to a hairy, 4-legged land mammal that eventually led to the formation of flippers without phalanges, a blow hole that became more dorsal, and other defining features. All of this has been backed by fossil evidence, especially that found within a certain desert region (can’t remember the name) that has a vast amount of whale fossils from many different time periods

If the female fly has EE and the male fly has EE, what are the possible percentages of phenotypes and genotypes of their offspri

algol [13]

Answer:

100% EE, 100% red eyes

Explanation:

For an organism, the genotype refers to the genetic characteristics of the organism while the phenotype refers to the physical characteristics of the organism.

The red eyes (E) is dominant while the white eyes (e) is recessive.

Since both parents are EE, the genotype of their offsprings would be EE, EE, EE, EE

That is: EE × EE = EE, EE, EE, EE

Hence the genotype is 100% EE.

Also, the phenotype is 100 red eyes.
