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?
different ways in which individuals with particular trait may increase are -if that particular trait provides them with some sort of support to undergo the circumstances they are found in, we can also call it natural selection -or due to any genetic drift, that is a natural calamity, also called a chance selection
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 Nissan Motor Car Carrier's population?
As of 2021, Nissan Motor Car Carrier does not have a "population" as it is a company specializing in automobile transportation logistics, not a residential community. It is a commercial entity that operates a fleet of car carriers to transport vehicles to different locations.
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.
How is a lethal allele maintained in a population?
A lethal allele is maintained in population for example when you use bug spray on cockroaches there will be at least one cockroach with an allele that protects it from the bug spray, it then breeds and the allele Is passed to it's offspring and they will also be immune to the pesticide. Those babies will most likely breed with each other when they are mature passing on the allele from both of the parents making the offspring 100% immune. It's the same concept for lethal alleles.
Are II-1 and II-2 carriers of the trait?
Without specific information on the trait in question or the family pedigree, it is impossible to determine if II-1 and II-2 are carriers. A carrier typically refers to an individual who has a recessive allele for a genetic trait but does not express the trait themselves. Genetic testing and analysis of multiple family members would be needed to confirm carrier status.
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.
What do half shaded circles mean for pedigrees?
In pedigree charts, half-shaded circles represent individuals who are carriers of a specific genetic trait or disorder but do not express the trait themselves. This typically indicates that the individual has one copy of the recessive allele associated with the trait, while the other copy is dominant. Carriers can pass the recessive allele to their offspring, potentially resulting in affected individuals if both parents are carriers.
Why is it possible that a majority of people may display a recessive trait?
It is possible for many people to display a recessive trait because the people have two recessive genes. Dominant simply means it will trump a recessive gene, it does not mean it is the most widely seen gene in a species.
How is a recessive trait in a pedigree?
In a pedigree, a recessive trait is typically represented by filled-in shapes (squares for males and circles for females) to indicate individuals who express the trait. A recessive trait appears in an individual only if they inherit two copies of the recessive allele, one from each parent. Consequently, unaffected parents can have affected offspring if both are carriers of the recessive allele. The pattern often shows skipped generations, as the trait can be passed through carriers without manifesting.
What is the frequency of carriers of albinism in the population?
12
How long does it take for a trait to manifest in a population?
The time it takes for a trait to manifest in a population can vary depending on factors such as the trait's heritability, selective pressures, and the population size. In some cases, a trait can appear relatively quickly through natural selection if it provides a significant advantage. However, in other cases, it might take many generations for a trait to become prevalent in a population.
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
Can males be carriers of sexlinked traits?
No. Carriers are people that carry the gene for something but exhibit no phenotype for it. Since males have no extra copy to hide a recessive trait, they cannot be carriers for sex linked traits.Answ2. Followers of this question should consult say haemophilia in wikipedia.com.
