Explain how the inheritance patterns of many traits (such as petal color in snapdragons, or skin color in humans) cannot be acco

unted for by Mendelian genetics.

Answer:

Petal color in snapdragon is an example of incomplete dominance and deviates from Mendel's law of dominance.

Skin color in humans exhibits a continuous variation and is regulated by more than one genetic loci.

Explanation:

Two alleles of a gene do not always exhibit the dominant-recessive inheritance as shown by Mendel. The alleles controlling the petal color in Snapdragon exhibit incomplete dominance since the allele "R" is not able to produce enough pigment in heterozygous condition to completely mask the effect of the recessive allele "r" Therefore, the heterozygous genotype "Rr" gives pink color to petals.

Mendel showed that each genetic trait is regulated by one gene and exhibit discontinuous variations. This is not followed by skin color in humans which is a polygenic trait with multiple genes regulating it. Here, a range of phenotype is present which is regulated by the sum total of the dominant alleles of all the genes involved controlling the melanin production.

Consider the classifications of bone, and examples of each. which classification applies to bones used primarily for movement ra
-BARSIC- [3]

Long bones are used primarily for movement rather than protection. A few examples of long bones are the humerus, tibia, and phalangeal bones.

The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones. They consist of a long shaft with two bulky ends or extremities. Osteoblasts are cells responsible for the secretion and deposition of bone morphogenetic proteins (BMPs) into the extracellular matrix during bone formation.

Appositional growth is the increase in the diameter of bones by the addition of bone tissue at the surface of bones. Bone remodeling involves the processes of bone deposition by osteoblasts and bone resorption by osteoclasts.
