Answer:Recessive traits
Explanation: Albinism is a reccessive traits whose effect have been suppressed by the dominant traits in the parents phenotype.
Complete dominance occurs when an allele A completely dominate over allele a in the genotype of an organism.
For the parents to have given birth to a non albino it means they are heterozgous dominant(Aa) and a cross between two heterozygous dominant parents will result in one homozgous non albino,2 heterozygous non-albino and 1 homozygous albino with the phenotypic ratio of 1AA 2Aa,1aa
The circulatory and skeletal systems work together in the following way: skeletal system produces cells in the bone marrow while the circulatory system transports cells where they need to go (option A).
<h3>What is skeletal and circulatory system?</h3>
Skeletal system is the system that works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals.
Circulatory system, on the other hand, are parts of an animal body comprising the heart, veins, capillaries and arteries. It circulates blood and lymph through the body.
According to the above description of both systems, the skeletal system produces blood cells in the bone marrow while the circulatory system transports these cells.

The presence of a controlled substance must be proven in both the blood and the organs before it can be considered as a cause of death.
A controlled substance is the one that is prohibited or available under strict regulations by the law of a country or state. These are usually the drugs that can result in addiction or serious diseases in an individual. Such substances are only available for medicinal purposes.
Blood is a red colored fluid present inside the body. It is red due to the presence of a pigment called hemoglobin. The blood is responsible for the transport of substances across the whole body, like oxygen, hormones, carbon dioxide, waste material, etc.
