Comparing genetic sequences is the most accurate way of determining evolutionary relationships. This is a quantitive measure, ( it uses numbers) we can use gene sequencing to identify how much of the genetic sequence in A is the same in organism B. The greater the similarities the more likely it is they have recently evolved from a common ancestor. The closer the ancestor, the less time has passed which means there’s been less time to develop mutations a base variation. That’s why there’s more genetic similarities between two things that are closely related.
Hope that makes sense
Answer:
Pleiotropy.
Explanation:
Pleiotropy may be defined as when the single gene shows the multiple phenotypic traits. The gene is known as the pleiotropic gene and its mutation may affect the several phenotype expression.
The frizzle gene control the multiple phenotype effects like defective feathers, high blood flow, low egg lay rates and high metabolic rates. This is a case of pleiotropy because here a single gene is responsible for the multiple phenotypes.
Thus, the answer is pleiotropy.
The major muscles involved while performing a wall sit or squat are the quadriceps muscles.
Explanation:
Exercises like wall sit or squat are an isometric exercises which works the entire group of lower body muscles.
Isometric exercises are endurance building exercises which improves the muscle endurance by holding it in a position for longer time. These exercises does not involve any big bodily movements but works by tensing the muscles.
Both these exercises primarily involve the front thigh muscles or the quadriceps. Squats and wall sits help to tone and shape the quads and other muscles involved. The angle of the body should be maintained at right angle to reduce the pressure on these muscles.
Other muscles which are involved in these exercises are the hamstrings, core, lower back muscles etc.
