Hemophilia, a blood clotting disorder, is an example of a sex-linked recessive defect. It occurs more commonly in males because the gene for hemophilia is located on the X chromosome. Females are usually carriers of the gene but are less likely to exhibit symptoms.
Sexlinked and recessive.
Color blindness is a recessive trait, meaning that an individual needs to inherit two copies of the gene for color blindness (one from each parent) in order to be color blind. If an individual inherits only one copy of the gene, they are considered a carrier and will not exhibit color blindness.
Anencephaly is a neural tube defect that is typically considered a sporadic condition caused by multifactorial and environmental factors, rather than being directly linked to a single gene that follows traditional dominant or recessive inheritance patterns.
X linked diseases when recessive are only present in female children when both parents have the disease. If the mother is only a carrier of the disease then each male child would have a 50% probability of having the disease, but no female children would be affected (50% would be carriers).

A homozygous recessive organism would have two copies of the same recessive allele for a particular gene. This means that both alleles carried by the organism would be the recessive form.
Sexlinked and recessive.
true
autosomal recessive
Inbreeding
recessive defect meaning that both copies of the chromosome must have the defect before it can be expressed. Females who have one X chromosome without the defect do not get this disease. Males, since they only have one X chromosome, get the disease
Chocolate is a regional name used by racing pigeon breeders for a recessive opal pigeon. All racing pigeons can live up to about 12-15 years with a rare number of them living to about 20. And even though you didn't specifically ask this, recessive opal is a non-sexlinked (autosomal) recessive.
Genes that are location on the sex chromosomes.
Color blindness is a recessive trait, meaning that an individual needs to inherit two copies of the gene for color blindness (one from each parent) in order to be color blind. If an individual inherits only one copy of the gene, they are considered a carrier and will not exhibit color blindness.
Morquio's Syndrome is a rare, usually inherited disease. The chances of getting this autosomal recessive birth defect is 1 in 200,000.
Wolman's disease is caused by a genetic defect (with a recessive pattern of inheritance) that results in deficiency of an enzyme that breaks down cholesterol.
If you selectively breed two animals with a recessive trait, they will pass on that trait to their offspring. A recessive allele must appear twice in a genotype to appear physically. I hope I answered your question.
Anencephaly is a neural tube defect that is typically considered a sporadic condition caused by multifactorial and environmental factors, rather than being directly linked to a single gene that follows traditional dominant or recessive inheritance patterns.
