Answer:

In the modern classification system birds are in a separate class from reptiles, but fossil evidence shows they have common ancestors.

Birds refer to the group of organisms which are endothermic in nature, have feathers, beaks, four-chambered heart, high metabolic rate, lay hard-shelled eggs and lightweight skeletons.  

In biological classification, they are classified under the class Aves.

Reptiles are four-limbed organisms which come under the class Reptilia.

However, biological and fossil evidence show that birds and reptiles shared common ancestors. It is believed that birds have evolved from the reptiles. Most of the scientists believe that birds are the specialized subgroup of theropod dinosaurs.

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.
