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.
Why were heterozygous individuals called carriers for non-sex-linked and x-linked recessive patterns of inheritance?
I don't know and don't care
In a heterozygote the allele that does not affect the trait?
The allele that does not affect the trait in a heterozygote is known as the recessive allele. This allele is masked by the dominant allele, which determines the observable trait. However, the recessive allele can still be passed on to offspring if both parents are carriers.
What is the pattern of inheritance for a sex-linked recessive trait in a pedigree?
In a pedigree, a sex-linked recessive trait is passed down from carrier mothers to affected sons. Daughters of carrier mothers have a 50 chance of being carriers themselves. Sons of affected fathers do not inherit the trait.
Can a human pedigree be used to detect a recessive trait?
Yes, a human pedigree can be used to detect a recessive trait by tracking the inheritance pattern of the trait within a family. Patterns such as multiple affected siblings, skip generations, and consanguinity can help identify recessive trait inheritance. Pedigree analysis can reveal carriers of the trait even if they do not show symptoms.
What are maintained in the population by carriers of the trait?
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.
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.
Can males be carriers of sexlinked traits?

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.
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.
What is meant by recessive trait when discussing genetics?
When discussing genetics, recessive trait refers to the fact that the offspring of two parents must inherit two copies of a gene to expose the trait. This would mean that both parents must be carriers of said gene in order for their offspring to show a recessive trait.
Can sickle cell trait skip generations?
yes it can skip a generation, since it is a Mendel inheritance. and it is a reccesive trait. therefore offspring's can have two unaffected parents but chances are both parents might be carriers
