Answer:
hitchhiker effect
it is an exaptation
Explanation:
Adaptation is a property which occurs due to change in the environmental conditions of an organism. Some traits of organisms are not adaptation because sometimes the function of a trait changes due to evolution which we called exaptation. It also occurs due to hitchhiker effect, this effect occurs when the change occurs in the frequency of allele not due to natural selection but due to selective sweep with the nearby gene.
Answer: Classification\
Explanation:
Classification is the arrangement of organisms into orderly groups based on their similarities. In order to classify an organism, a biologist must use a system that groups organisms according to shared characteristics and their relationships between one another.
Its a sex linked disorder and it makes stopping the bleeding slower in affected individuals.
<h3><u>Explanation:</u></h3>
Hemophilia is a sex linked recessive disorder which occurs due to a gene present in the X chromosome. The presence of this gene in males surely make the individual hemophilic because the Y chromosome doesn't contain any dominant factor of this gene. In females, the recessive individuals become carriers without expression of this gene. Only the dominant individuals in females expresses Hemophilia.
Its a disease where the Christmas factor (Factor IX) or the antihemophilic factor(Factor VIII) is absent in the affected individual. This makes the cascade theory incomplete and there's a defect in blood clotting in both the intrinsic and extrinsic pathways. Thus the persons if starts bleeding, loses a lot of blood before coming to a stability.
