Answer / sivani in sex linked diseases the defeceted genes are present on the sex chromosomes attached to them whereas in sex influenced diseases defective genes are present on the other. Sex-influenced dominance is the phenomenon in which the manifestation of a phenotype of a gene in heterozygosity depends on the sex of the individual for example, hereditary baldness is a dominant phenotypical form if the individual is male and is a recessive form if the individual is female.

It is important to distinguish between sex-linked characters, which are controlled by genes on sex chromosomes, and two other categories sex-influenced traits sex-influenced or sex-conditioned traits are phenotypes affected by whether they appear in a male or female body. Unlike sex linked diseases, sex influenced diseases are not reserved solely for the male however, the diseases occur in males much more frequently than in females this is because sex influenced diseases occur from imbalances in testosterone, much more highly concentrated in males. Best answer: sex influenced inheritance: these traits are expressed to some degree in both sexes, but are differentially affected by sex hormones examples include amount of body hair, muscle mass, and male pattern balding in the case of pattern balding, there is an autosomal gene pair that determines a propensity to the condition.
- expressed in only one sex, although the gene that determines that trait is not x(sex)-linked eg, male-limited precocious puberty -autosomal dominant - secondary sexual characteristics and growth spurt around 4 yo. Sex-linked traits are genetic characteristics determined by genes located on sex chromosomes sex chromosomes are found within our reproductive cells and determine the sex of an individual sex chromosomes are found within our reproductive cells and determine the sex of an individual.
Sex-linked diseases are passed down through families through one of the x or y chromosomes x and y are sex chromosomes dominant inheritance occurs when an abnormal gene from one parent causes disease, even though the matching gene from the other parent is normal. Sex linkage is the phenotypic expression of an allele related to the allosome (sex chromosome) of the individual in autosomal chromosomes both sexes have the same probability of existing (see fisher's principle), but since humans have many more genes on the female x chromosome than on the male y chromosome, these are much more common than y-linked traits.
There are thousands of cases of sex linked and sex influenced diseases worldwide these diseases can range from a social inconvenience, to a fatal ailment in sex linked diseases, like muscular dystrophy, hemophilia and color blindness, only males are affected.
