Blue eyes, green eyes, hazel eyes, grey eyes, colorblindedness, light red hair, no dimples, nearsightedness, sickle cell anemia, cystic fibrosis, straight hair, blonde hair, attactched earlobes, no freckles, thin lips, baldness, normal hairline, normal digits, normal number of digits, hemophilia, ALBINISM, and deaf mutism.
Both X chromosomes must carry the recessive trait. Since males only have one X chromosome, it is much easier for males to have the recessive phenotype. Put another way, a female would have to receive an X chromosome with the recessive gene from both parents, which would mean the father already displays the recessive disorder.
An example of a homozygous recessive genetic disorder is the eye color. the dominant eye color is brown but a homozygous recessive genetic disorder it's haze;, blue, gray, etc.
yes it is, only 1 mutation to the lmna gene is sufficent for someone to express traits regarding progeria
Phenylketonuria is an autosomal recessive genetic disorder. The enzyme phenylalanine hydroxylase is necessary to metabolize phenylalanie, but when this enzyme doesnt work, phenylaline accumulates and is detected in the urine. The disease is detected during pregnancy, and if treated right away the newborn can develop normally. However, if left untreated, the brain will not develop properly.
Recessive allele disorders are just as they sound - they are disorders that are a result of a prevalent recessive allele in one's genetic makeup. A recessive allele disorder will rarely occur since it is dependent on the crossing of two heterozygous parent cells, but it can lead to interesting consequences. An example of a recessive allele disorder is hemophilia - the body's inability to clot blood - and it has affected much of the European royalty in history, such as Queen Victoria of Great Britain.
If a genetic disorder is carried on a recessive gene, offspring will only have the disorder if both parents have the recessive gene.
Cystic Fibrosis is a recessive homozygous genetic disease

Muscular dystrophy is a sex-linked recessive disorder.

Somatoform disorder is a disorder that makes people perceive pain as if they have a physical injury or illness, thus resulting in a somatic behavior.
You did not list a "these" to chose from.
The probability would be 0.5 or 50%. A heterozygous woman will pass on the X chromosome with the recessive allele to 50% of her sons, and since the disorder is recessive, the son would only have the disorder if the X chromosome with the recessive allele is inherited from the mother.
Alleles can be either dominant or recessive. They can be identical or different for any given gene in a somatic cell, and can represent alternative forms of a gene.
No. Autism is a neurodevelopmental disorder
The child will have the disorder, only if the recessive allele from both the parents is transferred to the child. Therefore, the probability is 1/4.
It is an X-linked recessive disorder.
