I am writing a speech on genetically engineered foods, I need to know what are benefits, risks, and if the benefits outweigh the risks. I need to collect multiple view points of this question. Then I need to analyze it and formulate a statement to present in my speech.

Is there any biochemistry and biogeographical evidence supporting the evolution of birds from reptiles or dinosaurs. Such as similarities in dna structure etc?

Sources would be a great help as I am doing an assignment on this.

As far as I know artery carries pure blood - it braches into arterioles - it reaches cells - arterioles divide into fine capillaries- interact with cells- provides oxygen , take CO2 and other waste materials out. Then this capillaries join to make larger vessel known as vein -veins carry waste materials , CO2 etc.
But I have recently learned that the renal arteries do contain waste materials and they are filtered via neprons located at two kidneys.
Now my question is, how are this waste materials get into artery blood which(artery) is not supposed to interact with any cells?
Please help!!

An Avian Biologist studying a species of parakeet in Australia noticed that in the wild the parakeets had either red or green tail feathers. After many crosses the scientist obtained a true breeding red individual and crossed it to a second true breeding red individual that she had obtained in a separate series of crosses. Much to her surprise when the F1 progeny were obtained all of the birds were green. She then self crossed the F1 birds with the following results: 45 green birds and 35 red birds. After seeing these results she thought she understood what was going on but continued crossing F1 birds over the next year and obtained these results: 921 green birds and 704 red birds.

What mode(s) of inheritance are demonstrated by the above crosses? How many genes are involved?





What were the genotypes of the original true breeding red stocks and the green progeny?














Why was it important to continue crossing F1 birds over the course of that year instead of relying only on the original results?
