Sex-linked disorders are genetic conditions caused by mutations on the sex chromosomes. Symptoms of sex-linked disorders can vary widely, but often include physical abnormalities, intellectual disabilities, and other health issues. These disorders are typically inherited in an X-linked recessive pattern, meaning they are more common in males because they only have one X chromosome. Females are usually carriers of the mutated gene but may not show symptoms.

Is the inheritance pattern of the BRCA1 gene dominant or recessive?
The inheritance pattern of the BRCA1 gene is dominant.
The inheritance pattern that occurs equally in both sexes and skips generations is?
An example of an inheritance pattern that occurs equally in both sexes and skips generations is autosomal recessive inheritance. This means that for a child to inherit the trait or disorder, both parents must be carriers of the recessive gene. The trait may not appear in every generation due to the need for both parents to be carriers.
Which pattern of inheritance would account for human height?
Human height is typically determined by polygenic inheritance, where multiple genes contribute to the phenotype, along with environmental factors. This results in a continuous range of heights in a population. This pattern of inheritance contrasts with Mendelian inheritance, where traits are controlled by a single gene.
What pattern of inheritance would lead a geneticist to suspect that an inherited disorder of cell metabolism is due to a defective mitochondrial gene?
The disorder would always be inherited from the mother because the mother's mitochondrial gene is the only one that survives when the zygote is formed. The gamete from the mother contains all the information. The head of the father's sperm is the only part that survives during fertilization. The tail of the sperm containing the male's mitochondria (an their genes) is lost when the zygote begins development. Thus it is only from the mother that the disorder can be inherited.
What is the a pattern of inheritance in which certain characteristics carried on the X chromosome inherited from the mother are transmitted differently to her male and female offspring called?
This pattern of inheritance is called X-linked inheritance. It involves genes located on the X chromosome, leading to different inheritance patterns in males (who have one X chromosome) and females (who have two X chromosomes).
What does a genetic counselor construct to show the inheritance pattern of a genetic disorder within a family?
Its a pedigree. A pedigree shows the inheritance of a genetic disorder within a family and can help to determine the inheritance pattern and whether any particular individual has an allele for that disorder.
What does genetic counselor construct to show the inheritance pattern of a genetic disorder within the family?
A Pedigree
What is the inheritance pattern to Marfan Syndrome?
Marfan syndrome is an autosomal dominant disorder. An affected person has a 50% chance of passing it on to each offspring, regardless of gender.
A psychological disorder is a pattern of symptoms that cause _____ and impair the ability to function in one or more important areas?
significant personal distress
Is the inheritance pattern of the BRCA1 gene dominant or recessive?
The inheritance pattern of the BRCA1 gene is dominant.
What are the inheritance patterns for SMA?
Inheritance pattern for most forms of SMA is autosomal recessive, meaning that both parents are carriers of the disorder, and the chance of having a child affected with the disorder is 25% with each pregnancy.
Is cleft lip and palate an autosomal or sex linked disorder?
Cleft lip and palate is not a sex-linked disorder. It is a common birth defect that occurs due to both genetic and environmental factors, with a multifactorial inheritance pattern involving multiple genes as well as environmental influences.
What is the difference between hypochondriasis and somatization disorder?
The primary difference between hypochondriasis and somatization disorder is that people manifesting the former are fearful that their symptoms indicate a serious disease(s), whereas those with somatization disorder typically do not progress beyond a concern with the symptoms themselves.
Gaucher disease is caused by what genetic disorder?
Gaucher disease has a recessive pattern of inheritance, meaning that a person must inherit a copy of the defective gene from both parents in order to have the disease.
Who is the man who discovered the pattern of genetic inheritance?
Gregor Johann Mendel is credited with discovering the pattern of genetic inheritance
Is hemophilia a pattern inheritance?
Yes, hemophilia is typically inherited as an X-linked recessive disorder, meaning it is passed down through a mutation on the X chromosome. This pattern of inheritance results in the condition being more commonly seen in males, while females are often carriers of the gene.
The inheritance pattern that occurs equally in both sexes and skips generations is?
An example of an inheritance pattern that occurs equally in both sexes and skips generations is autosomal recessive inheritance. This means that for a child to inherit the trait or disorder, both parents must be carriers of the recessive gene.
