What does the normal gene responsible for hyperkalemic periodic paralysis responsible for?
The normal gene is responsible for a muscle protein controlling the flow of sodium during muscle contraction.
What determines if the gene for periodic paralysis is passed on?
The gene for periodic paralysis is passed on through inheritance from parents to their children. It is determined by the specific genetic mutation present in the affected individual's DNA. Offspring have a 50% chance of inheriting the gene if one parent carries the mutation.
A gene whose code is not expressed unless a similar allele is present is called an?
recessive gene
What is a form of a gene that always has its effect when it is present?
dominant
How many gene is present in one chromosomes?
A given gene is present on exactly two chromosomes in a somatic cell.
What gender has a greater genetic risk for hyperkalemic periodic paralysis?
The gene for hyperkalemic PP affects virtually all who inherit it, with no difference in male-vs.-female expression.
What does the normal gene responsible for hyperkalemic periodic paralysis responsible for?
The normal gene is responsible for a muscle protein controlling the flow of sodium during muscle contraction.
How does the gene for hypokalemic periodic paralysis present?
The gene for hypokalemic PP is present equally in both sexes, but leads to noticeable symptoms more often in men than in women.
What determines if the gene for periodic paralysis is passed on?
The gene for periodic paralysis is passed on through inheritance from parents to their children. It is determined by the specific genetic mutation present in the affected individual's DNA. Offspring have a 50% chance of inheriting the gene if one parent carries the mutation.
What sex is more at risk for hypokalemic periodic paralysis?
The gene for hypokalemic PP is present equally in both sexes, but leads to noticeable symptoms more often in men than in women.
What does the normal gene responsible for hypokalemic periodic paralysis responsible for?
The normal gene is responsible for a muscle protein controlling the flow of calcium during muscle contraction.
What is the term for when two or more versions of a gene are present in an organism?
The term for when two or more versions of a gene are present in an organism is called "gene polymorphism."
How many alleles are typically present in a gene?
Typically, there are two alleles present in a gene, one inherited from each parent.
The total number of genes present in a population is the?
gene pool
Which type of gene or gene combination can be present in a generation without affecting phenotype?
A recessive gene or gene combination can be present in a generation without affecting the phenotype if it is masked by a dominant gene. This means that the trait associated with the recessive gene will only be expressed if an individual inherits two copies of the recessive gene.
A gene whose code is not expressed unless a similar allele is present is called an?
recessive gene
A gene that can be masked by another gene is called?
A gene that can be masked by another gene is referred to as a recessive gene. This means that the trait associated with the recessive gene is expressed only when two copies of the gene are present.
