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.

Which trait below is a characteristic of energy carriers?
Able to release energy easily.
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 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.
A pedigree chart can show a trait that is?
Inherited through family relations. Like a family tree, but using squares for males and circles for females. Shaded shapes contain the trait that the chart is displaying. Half shaded shapes symbolize carriers for the trait being represented by the chart.
A dominant x linked trait would be more common in males or females?
If the trait is recessive and on the male chromosome (Y), then it is impossible for females to get it since they do not possess a Y chromosome. If you meant a recessive sex-linked trait on the X chromosome (like male pattern baldness), then males are still more likely to get it since they only receive one X chromosome and if it is affected they would automatically have the trait (whereas females have 2 copies and would only have the trait if both parents passed on chromosomes containing the recessive allele.) Females can be carriers, though. If they are a carrier (have one affected X chromosome) for the trait then their male children would have a 50% chance of inheriting the trait and their female children would have a 50% chance of becoming carriers.
What are maintained in the population by carriers of the trait?
recessive
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.

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.
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.
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
Why do you have blue eyes when your dad has brown eyes?
Blue eyes is a recessive trait. Both parents could be blue gene carriers.
