Answer:
For example, cells in the interior of the body may be signaled by genes to become either muscle or connective tissues, while other cells on the exterior of the body will be signaled to become epithelial cells.
Explanation:
Answer:
E (Red shows incomplete dominance over white)
Explanation:
This portrays a monohybrid cross involving a single gene coding for flower colour in snapdragon plants. According to the question, a purebreeding red flowered (homozygous) plant is crossed with a purebreeding white flowered (homozygous) plant to produce an all pink flowered offspring. This phenomenon is called INCOMPLETE DOMINANCE.
Mendel, in his experiments, discovered that an allele can mask the expression of another in a heterozygous state. He called the allele that masks DOMINANT allele while the allele that is masked RECESSIVE allele. However, exceptions like INCOMPLETE DOMINANCE, has occurred in the sense that an allele does not completely mask the expression of its allelic pair, instead an intermediate phenotype, which is a combination/blending of both parental phenotypes is produced.
In this case, the red flowered snapdragon (RR) does not completely cover up the expression of white flower (rr), hence a hybrid/heterozygous offspring is produced that combines the phenotypic characteristics of both parents to form an intermediate flower colour (pink). Hence, it can be said that Red flower is incompletely dominant over white flower or no allele/trait is dominant or recessive to another.
Advantages:
The plant is an integral member of the regional desert ecosystem and native pollinators such as hummingbirds and carpenter bees consume ocotillo nectar for nutrients. The hummingbird and the ocotillo have an important plant-pollinator relationship, as the hummingbird relies upon the flowers for a nectar source.
Dr. mengele invented the scientific method, which is controlling variables in experimentation to find evidence for theories.
Cattle depend on microorganisms in their digestive tract to digest the cellulose in their diets. The Cattle and the microorganisms are Symbionts. Since they are not able to digest the cellulose that they eat from plants.
