In sexual reproduction, will an offspring show a recessive trait if just one of its parents has recessive alleles for that trait? Explain your answer.

Answers

Answer 1

Answer:

No, they will not

Explanation:

In this question, we assume that the parents have genotypes of rr and RR (I use "r" out of convenience). If we cross both of these parents, it is impossible for any of the offspring to be rr like the one parent. They would all be heterozygous. If the other parent had a single recessive allele, then it would be possible.  

Hope this helps!

Hope this helps you!

Answer:

A.  a joint's maximum range of motion

Explanation:

A goniometer is a device that is used to measure the maximum arc of motion made by a joint. The traditional goniometer consists of a protractor and two extending arms ,one of the arms is movable while the other one is stationary.To take measurements the center of the goniometer is aligned with the center of a joint. Then the arm of the goniometer is moved until it aligns with the limb that has been moved to a maximum position that the joint allows. The angle made between the two arms of the goniometer is measured in degrees and is the maximum range of motion of the joint.
