The elbow (or olecranon joint) is the part of the upper limb between the arm and forearm. This articulation includes the region of the "elbow fold" (or ulnar fossa). It is a synovial joint complex of the upper human limb connecting the arm to the forearm. He thus unites three bones between them: the radius, the ulna and the humerus.
<span>The ulna is a long bone of the forearm, located at its inner side while the radius, the second bone of the forearm, is located at the level of the outer part (the same side of the thumb)</span>
Answer:
Mendel disproved the blending theory of genetics when he cross pollinated tall and short pea plants and the offspring were either tall or short, not medium like the blending theory of genetics suggests.
Explanation:
Answer: Gravity is by far the weakest force we know.
Gravity and weight are not the same thing.
Gravity makes waves that move at light speed.

Answer:
9:3:3:1
Explanation:
This type of crossing that involves two characters is referred to as dihybrid crossing. Generally, when there is a dihybrid crossing for heterozygous genes for both parents, the phenotypic ratio is usually 9:3:3:1 as shown in the figure in the attached document below.
Assuming the colour is White (P) and Black (p) and the
Height is Tall (T) and short (t)
The possible phenotypes will be in the ration
9 - White and Tall
3 - White and short
3 - Black and Tall
1 - Black and short
It should be noted that phenotypic ratio (phenotype) describes the outward appearance (what can be see physically) and not the genetic make-up. Thus, where there is a dominant character like P or T, the recessive characters are not considered to have been expressed.
