What is the meaning of a pleiotropic trait and provide an example. Pleiotropic trait occurs when a single mutant gene affects two or more distinct and seemingly unrelated traits, for example, Marfan syndrome have disproportionately long arms, legs, hands, and feet; weak aorta, and poor eyesight due to the production of abnormal connective tissue
Pleiotropic trait is a single gene that has multiple effects on an organism. An example is the mutation that causes sickle cell anemia. This single gene mutation sickle the blood cells, leading to systemic symptoms such as heart, lung, and kidney damage, muscle pain, weakness, and generalized fatigue.
What is the meaning of a pleiotropic trait and provide an example. Pleiotropy occurs when one gene influences two or more seemingly unrelated phenotypic traits an example of pleiotropy that occurs in humans is sickle cell disease. Sickle cell disorder results from the development of abnormally shaped red blood cells.
Special structures at the centromere region called kinetochores provide a place of attachment for kinetochore microtubules. Nonkinetochore microtubules overlap those from the opposite pole. ... What is a polygenic trait? Give an example. ... What are pleiotropic effects? Give a gene that shows pleiotropic effects. One gene that has multiple ...
Genes are segments of DNA located on chromosomes. Genes exist in alternative forms called alleles. Alleles determine distinct traits that can be passed on from parents to offspring. The process by which genes are transmitted was discovered by Gregor Mendel and formulated in what is known as Mendel's law of segregation.

What are alleles? An allele is an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome. These DNA codings determine distinct traits that can be passed on from parents to offspring.

Meiosis goes through two divisions, one in meiosis 1 and one in meiosis 2. In the end, it results in four cells and each cell only contains half of the genetic material. At fertilization male and female gametes come together to form a new being with half of its mothers genes and half of its fathers.

it is a recessive trait and recessive traits always arise by mutation. achondroplasia is caused by an allele that is always expressed, so the parents couldn't have the allele. achondroplasia is a relatively rare disorder. such mutations are statistically predictable.
The heterozygote expresses the phenotype of both homozygotes. The phenotype of the heterozygote falls between the phenotypes of the homozygotes. An individual with (naturally) curly hair and an individual with (naturally) straight hair mate; all of their offspring have (naturally) wavy hair.
one parent is heterozygous and one parent is homozygous recessive. both parents are homozygous dominant. one parent is homozygous dominant and one parent is homozygous recessive. both parents are heterozygous for both genes.
In the diathesis-stress model, a diathesis is. a. a distal necessary or contributory cause of a mental disorder. b. a sufficient cause that is distal from the onset of symptoms. c. a necessary or contributory cause that is proximal to the onset of symptoms.
a necessary or contributory cause that is proximal to the onset of symptoms. d. a biological vulnerability that virtually guarantees the development of the disorder. a. a distal necessary or contributory cause of a mental disorder. Suppose that low self-esteem is a diathesis for developing depression later in life.
A protective factor is. a. an influence that modifies a person's response to environmental stressors. b. an influence that modifies a person's response to genetic problems.
d. a biological makeup that makes people more resistant to stress. a. an influence that modifies a person's response to environmental stressors. Ryan, age 8, was cut from the school soccer team. After the initial disappointment, he became a boy scout, which he really enjoyed.
Values are shared beliefs about what is good or bad, right or wrong, desirable or undesirable. The types of values held by a group help to determine the character of its people and the kinds of material and nonmaterial culture they create. Click again to see term 👆. Tap again to see term 👆.

These components are technology, symbols, language, values, and norms. How do cultural traits, cultural complexes, and cultural patterns differ? A culture trait is an individual tool, act, or belief that is related to a particular situation or need, such as using a specific greeting when meeting someone. Individual culture traits combine ...
A culture complex is a cluster of interrelated traits. The game of football is a culture complex that involves a variety of traits. Culture complexes combine to form larger levels called culture patterns. A culture pattern is the combination of a number of culture complexes into an interrelated whole. For example, the separate complexes of ...

Culture complexes combine to form larger levels called culture patterns. A culture pattern is the combination of a number of culture complexes into an interrelated whole. For example, the separate complexes of baseball, basketball, and other sports combine to form the American athletic pattern.

Here’s a quick and simple definition: A tragic hero is a type of character in a tragedy, and is usually the protagonist. Tragic heroes typically have heroic traits that earn them the sympathy of the audience, but also have flaws or make mistakes that ultimately lead to their own downfall. In Shakespeare's Romeo and Juliet, Romeo is a tragic hero. ...

Some additional key details about tragic heroes: The idea of the tragic hero was first defined by the ancient Greek philosopher Aristotle based on his study of Greek drama.
It also meant that the character should be both capable and powerful (i.e. "heroic"), and also feel responsible to the rules of honor and morality that guided Greek culture. These traits make the hero attractive and ...
Nevertheless, the essence of a tragic hero in modern times maintains two key aspects from Aristotle's day: The tragic hero must have the sympathy of the audience. The tragic hero must, despite their best efforts or intentions, come to ruin because of some tragic flaw in their own character.
Antihero: An antihero is a protagonist who lacks many of the conventional qualities associated with heroes, such as courage, honesty, and integrity, but still has the audience's sympathy.
He does a few good things, but only as long as it suits him—so he's a classic antihero. Byronic hero: A Byronic hero is a variant of the antihero. Named after the characters in the poetry of Lord Byron, the Byronic hero is usually a man who is an intelligent, emotionally sensitive, introspective, and cynical character.
