Answer:
Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. Sexual reproduction involves two parents and produces offspring that are genetically unique

Answer:
A. Genotypes: Rr
Phenotypes: All Pink
B. Genotypes in the F2 generation: RR, 2Rr, rr
Phenotypes: red, pink and white
C. 1RR (red): 1Rr (pink).
D. 1Rr (red) : 1rr (white).
Explanation:
This question involves one gene coding for flower color in snapdragon plants. The allele for red color (R) is incompletely dominant over the allele for white color (W), to form an intermediate pink color (RW).
A. If a red-flowered plant (RR) is crossed with a white-flowered plant (rr), the genotypes of the offsprings will be Rr with a pink color phenotype.
B. In the F2 generation i.e. Rr × Rr, the following will be produced: RR (red), 2Rr (pink), and rr (white).
C. if a red-flowered plant is crossed with a pink-flowered plant, the following will be produced: 1RR (red): 1Rr (pink).
D. if a pink-flowered plant is crossed with a white-flowered plant, the following will be produced: 1Rr (red) : 1rr (white).
The bones that make up the joint allow movement, but it is the muscles that pull the bones that produce the movement. Muscles are attached to bones by structures called tendons. Tendons must be both strong to facilitate movement and compliant to prevent damage to the muscle tissues. Ligaments, which are stiff structures that connect bones, help to prevent excessive movement. Muscles, tendons, and ligaments are attached around each joint at very specific positions, with joint surfaces shaped in exact dimensions. Fluid within most of the joints lubricates the joint surfaces to reduce friction and allow for lifelong use.
