Carriers of a trait maintain the genetic variation within a population by passing on the gene to their offspring but not necessarily expressing the trait themselves. This helps ensure the survival of the gene pool and provides adaptability to changing environmental conditions. Carriers may also pass on the trait to future generations who may express it under different circumstances.

What types of individuals in a population are represented by the two ends of a bell curve?
The individuals with extreme variations of a trait.
Will shift populations toward a beneficial but extreme trait value?
A process that shifts populations toward a beneficial but extreme trait value is called directional selection. This occurs when individuals with traits at one end of the spectrum have a higher fitness, leading to the gradual increase in frequency of that trait in the population over time.
What are the different ways in which individuals with a particular trait may increase in a population?
Individuals with a particular trait may increase in a population through natural selection, genetic drift, gene flow, and mutations. Natural selection favors individuals with advantageous traits, genetic drift leads to random changes in allele frequencies, gene flow introduces new alleles into the population, and mutations create new genetic variation.
What is a population attribute?
A population attribute is a characteristic or feature of a group of individuals within a population. Examples include age, gender, income, education level, or any other quantifiable trait that can be used to describe the population as a whole.
What is population replacement level?
Population replacement level refers to the fertility rate needed for a population to replace itself without migration, typically around 2.1 children per woman. This rate ensures the current population size is maintained over time. A fertility rate below the replacement level can lead to a declining population and various social and economic challenges.
How can a negative trait remain in a population over long periods of time?
because carriers are the fittest in the population of most diseases.
Are II-1 and II-2 carriers of the trait?
Yes II - 1 and II- 2 are carriers. They have a dominant trait but have a child with a recessive trait. They must be carriers.
Who has a sickle cell trait?
No. Many people become confused with that because the Sickle Cell trait is most common in Africa where the population is more black than any other race.
What is Le Trait's population?
The population of Le Trait is 5,292.
If both parents are carriers what will the child be?
When a recessive trait is inherited from both parents, it will be expressed. If the trait is hemophilia, the child will be a hemophiliac.
Which trait below is a characteristic of energy carriers?
Able to release energy easily.
What is the frequency of carriers of albinism in the population?
12
How do flies act as carriers of pathogenic bacteria among the human population?
how may flies may act as carriers of pathogenic bacteria among human population
What can cause particular trait to become more common in a population?
When it comes that a particular trait being spread though a population, it is called reproduction.
What is the pattern of sex linked inheritance?
In humans sex linked traits are passed on the X chromosome. (For the purpose of this discussion the trait being passed is recessive.) This means that a male parent cannot pass the characteristic on to his male offspring, but he can pass the trait on to his female offspring. The female parent can pass the trait on to any of her offspring. Both parents must carry the allele for the sex-linked trait (and pass it on) in order for a female child to have the characteristic. Male children that get the trait from their mother will have the trait no matter what the genetics of the father. If the female parent is heterozygous for the trait 50% of her male children will have the characteristic no matter the father's genetics for that trait. Assuming that the characteristic is not lethal and both parents are "carriers" (keep in mind that the father displays the trait and a heterozygous mother will not)... 50% of the sons will have the trait, 50% of the sons will not have the trait, 50% of the daughters will be homozygous for the trait and 50% will by heterozygous "carriers".
Can two parents with albinism have an unaffected child?
Yes, Albinism is a recessive trait. You may be carriers of it but it doesn't necessarily mean that your child will have it. Your parents could have been carriers of it but not had it. The albinism just happened to be mixes into your genes.
If you mother and father are both sickle cell carriers what are the chances that you will not have the trait?
It is impossible to predict what will happen with one person! In a population of 2,000 people, 1,000 women have sickle cell trait and 1,000 men do not. They marry. Each couple has 2 children. 1,000 children will have sickle cell trait and 1,000 children will not. In a population of 2,000 people, 1,000 women have sickle cell trait and 1,000 men have sickle cell trait. They marry. Each couple has 2 children. 1,000 children will have sickle cell trait, 500 children will not, and 500 children will have sickle cell anemia. No one knows which of those parents will produce which children. No one knows how to predict how your children will turn out.
