Duchenne muscular dystrophy is caused by a recessive allele on the X chromosome. This means that males are more commonly affected since they only have one X chromosome. Females can carry the allele but are usually not affected due to having a second X chromosome that often carries a normal copy of the gene.
If the disorder is caused by a dominant allele, you would expect to see affected individuals in every generation of the pedigree, as it only takes one copy of the dominant allele to express the disorder. Additionally, affected individuals would have at least one affected parent.
The liver.
if an indivigual has a dominent allele for a disease he/she is an affected individual.
Yes, pedigrees can effectively represent the inheritance patterns of color blindness, which is a recessive X-linked trait. In such pedigrees, affected males, who have only one X chromosome, will show the trait if they inherit the affected allele. Females, having two X chromosomes, must inherit two affected alleles to express the trait, making them carriers if they possess one affected allele. This results in distinct patterns of inheritance, with affected males often passing the allele to their daughters, who may become carriers.
The joints that are most commonly affected by Rheumatoid Arthritis are the joints most commonly used in everyday usage such as fingers, knees, legs and feet.

The BRCA2 mutation is associated with a variety of mutations across its gene. However, most commonly, the mutation is found in one allele of the BRCA2 gene located on chromosome 13.
In areas where it is still common, children are most affected.
If the disorder is caused by a dominant allele, you would expect to see affected individuals in every generation of the pedigree, as it only takes one copy of the dominant allele to express the disorder. Additionally, affected individuals would have at least one affected parent.
A heterozygous individual who has one allele for a disease but is not affected by it is considered a carrier. Carriers can pass the disease allele to their offspring but do not exhibit the symptoms themselves. This is common in genetic disorders that follow a recessive inheritance pattern.
The liver.
The shoulder, elbow, knee, and ankle joints are the most commonly affected by tendon injuries.
for son x chromosome comes from mother and y chromosome from father. If the mother had both allele got affected then the transfer of disease is 100 %. If only one allele is affected then 50% possibility of son getting affected
name the joints affected most frequently by contractes
Infants and children are most commonly affected by adenoviruses. Adenovirus infections can occur throughout the year, but seem to be most common from fall to spring
Indian women but males can also get infected.
