Example of a sexually influenced trait?
One example of a sexually influenced trait in humans would be haemophilia. The gene responsible for haemophilia is located on the X chromosome, and if a man receives a gene from his mother (men's X chromosomes always come from their mother) that is positive for this trait, he will exhibit haemophilia. Women must have two X chromosomes that are positive for haemophilia in order to exhibit the trait, because it is a recessive gene.
Is an organism with a recessive allele for a particular form of a trait will always exhibit that form true or false?
false
What type of alleles does a carrier have?
A carrier is heterozygous for a given trait. They would display the dominant trait but still be able to pass the recessive trait to their children.
Why term is used to describe organisms that pass the same form of a trait over many generations?
True breeding is used to describe organisms that pass the same form of a trait over many generations. True breeding is the term is used to describe organisms that pass the same form of a trait over many generations.
Is it possible for two parents with brown hair to have an offspring with blonde hair?
If two blonde haired people have a child the child will be blonde as everybody has two hair genes (one from each parent) and you pass one of your genes to your child, to be blonde you have to have two blonde haired genes and as you can only pass blonde genes to your child they will certainly be blonde.Source(s):GCSE science lessons Hi I am sorry to rain on your party but i believe you are incorrect. The reason why is because you can carry a trait but if you are an owner of trait then you have that trait plus others. For example my aunt has blonde hair and her hubby has blonde hair that went to dirty blonde to brown naturally. However, they have a red-head. How is this possible? Doesn't heredity have rules? I am so confussed.
What is the probability that a parent carrying a dominant trait will pass that trait on to each child?
The probability that a parent carrying a dominant trait will pass that trait on is a 50% chance with each pregnancy
What is the genotype of a carrier of recessive disorder?
A carrier is someone who does not have a disorder but carries the allele on to offspring.
Which character trait does Balboa exhibit throughout the story?
ambition
What trait do the child and Zaroff have in common?
Both the child and Zaroff exhibit a sense of ruthless determination and cunning in their pursuit of their objectives. They are willing to go to great lengths to achieve their goals and are not easily deterred by obstacles or challenges.
How does sickle-cell trait differ from sickle-cell disease?
in sickle cell trait you don't actually have the disease. you are only able to pass the disease to your kids if you marry a person with sickle cell or that also has the trait. sickle cell disease is when you actually have the disease. you can pass it to your kids if you marry someone with the trait or the disease. if you marry someone without a trait or disease then your kids will most likely have the trait.

What is the genotype of a child if the mother is homozygous for the dominant trait and the father is homozygous for the recessive trait?
The dominant parent is most likely homozygous dominant, and the recessive parent has only the homozygous genotype. So the dominant parent can pass on only dominant alleles for this trait, and the recessive parent can pass on only recessive alleles for this trait. So all of the offspring would be heterozygous and have the dominant phenotype.
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".
Does the mother or father pass on the color blind trait?
It depends. If the child is male, the person to pass the trait on must be the mother. She may be a hybrid or color-blind herself for her to be capable of doing this. If the child is female, the father must be color-blind in addition to the mother being a carrier. Both have to donate the recessive gene to their daughter.
