Why can Cystic fibrosis be inherited even if neither parent has the disease?
Cystic Fibrosis is an example of a disease inherited as an autosomal recessive genetic disorder. Both parents of a baby who has Cystic Fibrosis have one abnormal recessive gene and one normal dominant gene and are therefore, Cystic Fibrosis carriers. Carriers are said to be heterozygous because they contain one normal copy of the gene and one abnormal copy. A baby who inherits cystic fibrosis has inherited the abnormal gene from both parents and is therefore said to be homozygous recessive.
If a genetic disorder is carried on a recessive gene which if any will have the disorder?
If a genetic disorder is carried on a recessive gene, offspring will only have the disorder if both parents have the recessive gene.
Is cystic fibrosis carried on a dominant of recessive gene?
Cystic fibrosis is an autosomal recessive genetic disease.
How could 2 parents with blood type A and B have a child with the blood type of O?
both parents carried the recessive gene for type O blood. the baby then inherited 2 recessive genes and received type O blood. the reason the parents didn't have type O blood is because they carried genes that were more dominant.
In Mendel's experiment why did wrinkled seeds show up in the F2 generation even though they were not present in the F1 generation?
Wrinkled seeds are recessive The F1generation carried recessive alleles.
A hereditary characteristic that carried by an individual but is not expressed in the phenotype is?
recessive
Does your eye color come from your culture?
Eye color comes from melanin levels within your eye. This can be inherited through parents. Although brown, and other dark pigments are usually more dominant. It is possible for a recessive trait to be inherited, if it is carried by either one of the parents. skin tone or cultural backgrounds does NOT affect eye color.
What is a recesive trait?
A recessive trait is one that is not always seen. Recessive traits can be carried in a person's genes without appearing in that person.
Most hormones are distributed throughout the body by the?
Hormones are carried around the body in the blood.
In Mendel's experiment why did wrinkled seeeds show up in the F2 generation even though they were not present in the F1 generation?
Because it's used to show up in only The F2 generation
Why do you have green eyes and your parents have brown?
Your parents carried the gene for green eyes as a recessive trait.
How is sickle cell anemia inherited?
This is inherited on the X chromoseome and is recessive. This means a female (who has XX chromosome pair) can only express the disease if she carries the trait on both chromosomes. This is because of the recessive nature of the gene. A male can only inherit the disease from his mother. This is he must have obtained his Y chromosome from his father so he obtains the X chromosome from his mother. A male cannot carry the gene without expressing it as he doesnt have another X chromosome to supress the recessive gene. ^ This answer is biologically incorrect because Sickle cell Anemia is actually autosomal recessive, not sex-linked recessive; this means that males and females are affected equally and it is NOT carried on the X chromosome. In order for the trait to show up in an individual, BOTH parents must be carriers of the disease (at least 1 sickle cell gene must be present).
