RrXtXt×RrXTY is representing the cross between the white eyed female and red eyed male.
Option D
<h3><u>Explanation:</u></h3>
The genes that are discussed here both are completely dominant over their recessive alleles. In the autosome, the dominant R gene is responsible for red eye and recessive r gene is responsible for sepia eye. But in allosome, the dominant T gene allows the eye colour to be expressed and the recessive t gene doesn't allow eye colour to be expressed and makes it white.
As the female do have 2 X chromosomes and the female is white eyed, then both the chromosomes of female have t gene.
As the male is red eyed and have one X chromosome, so the male must have atleast one R gene in autosome to make the eye colour red and must have T gene in his X chromosome to make it appear in phenotype.
So the most possible cross that is given here is RrXtXt×RrXTY.

Answer: I think this should be the completed question.
picks up fluid leaked from blood vessels and returns it to blood. disposes of debris in the lymphatic stream. houses white blood cells (lymphocytes) involved in immunity. the immune response mounts the attach against foreign substances within the body.
The correct answer is LYMPHATIC SYSTEM
Explanation:
It is lymphatic system because Lymphatic system is a system that consists of vessels, cells, lymphoid organs which include bone marrow and thymus which form lymphocytes, cells that helps in body immunity or defence against pathogens and they carries excess fluid from the blood stream, filtering and cleansing the body front pathogens,and eliminating nitrogenous wastes and also the regulate acid base electrolytes in the body.
