Answer:

Genes aren't eradicated from natural selection, but the chances of getting the phenotypes (the physical attributes of an organism based on the genes) go down as the organisms with those phenotypes die out.

Explanation:

Recessive genes are still present in, for example, a heterozygous genotype. but since there is a dominant, it covers the recessive gene and the phenotype won't have anything to do with the recessive gene (unless we are talking about incomplete or codominance).

Identify the letter that indicates the vessel that arises from the union of the left and right brachiocephalic veins.

Mrrafil [7]

While looking at the figure, the union of the left and right brachiocephalic veins is Point A.

<h3>What are brachiocephalic veins?</h3>

The internal jugular vein and the subclavian vein join to form the brachiocephalic veins, also known as the innominate veins, which are substantial venous systems in the thorax.
On the right side of the upper chest, the superior vena cava is formed by the union of the left and right brachiocephalic veins.
These blood arteries are an essential part of the circulatory system in humans because they facilitate the removal of deoxygenated blood from the head and upper limbs.
The internal jugular vein on the right and subclavian vein on the left combine to form the brachiocephalic veins. Both the vena cava and the brachiocephalic veins lack valves.

sweet-ann [11.9K]

Answer:

7%.

Explanation:

The recombinant progeny might occur due to the exchange of genetic material between non sister chromatids known as crossing over during the meiosis.

The chromosome sequence is DABC. A and B distance is 4 map units, B and C is 2 map units, B and D is 5 map units. The distance between A and D is 1 map unit that can be calculated by subtracting the distance between BD and AB ( 5-4). The CD map distance can be calculated by adding the distance between AD, AB and BC ( 1 + 4+ 2). The recombination frequency is equal to distance between them is 7%.

Thus, the answer is 7%.
