In genetics, the physical characteristics are referred as phenotype. Each character such as hair color in offspring is determined by a pair of genes.  One gene is inherited from father and other gene is inherited from mother. The phenotype is determined by the dominant gene. The recessive gene of a pair does not show its effect in heterozygous condition. Therefore, the offspring inherits a dominant gene and a recessive gene then the dominant gene will show the character. This is called Mendel’s law of dominance.

How does sunlight affect aquatic life in the Blue Cypress Lake?
wlad13 [49]

Answer:

Blue Cypress Lake, originally called Lake Wilmington, is a lake in Indian River County of the Treasure Coast in Florida. It is the largest lake in the Treasure Coast and Indian River County. It is the headwaters lake of the St. Johns River. The sources of water are several creeks from the south (Mudfish Slough, Padget Branch, Holman Canal, and Fisher Creek), two from the west (Trim Creek, Blue Cypress Creek), and Moonshine Bay from the North that flow into the lake. All the water flows out of the lake to the northwest into M Canal and Zigzag Canal. The lake is over 6,500 acres (26 km²) in size, 21 mi (34 km) in circumference, and has an average depth of 8 feet (2 m). The lake is 2,100 acres (8.7 km²) larger than Lake Washington, 27 mi (43 km) north of this lake. The lake's name comes from the blue appearance of the cypress trees as the morning sun's rays reflect off the water. A fishing camp called Blue Cypress Lakeside Cabins is 4 mi (6 km) off State Road 60. The Blue Cypress Village (about 70 units) is south of the small boat canal from the fish camp.
