zmey [24]

Answer:

D) a group of feathered, endothermic dinosaurs

Explanation:

Birds are a group of endothermic  dinosaurs, characterized by feathers, epidermal structures that form plumage. Warm-blooded animal species (endothermic) maintain the body temperature higher than their environment.

Answer A is false because although birds are feathered and lack teeth, they are NOT ectothermic lizards.

Answer B is false because although birds lay amniotiv eggs, birds are a different taxonomic group than mammals, and not all birds fly.

Answer C is false because although  some reptiles are closely related to birds, the current scientific consensus is that birds are a group of dinosaurs. Also, not all birds fly, and although they have lost the teeth, they  have NOT lost the amniotic egg.

Theoretically the father could be heterozygous and still have 11 brown eyed kids. This just means that the Dad always passed down his dominant gene.
