Answer:

The offspring of organisms that is reproduce through sexually are not genetically identical to their parents because the offspring contains genes from two parents.

Explanation:

Identical offspring is only formed when offspring is produced from one parent through asexual reproduction such as building, binary fission and fragmentation. In sexual reproduction, offspring is produced by the mating of two organisms i. e. male and female organism. That's why genes of offspring are different from their parents and offspring is not identical to parents.

Answer: offspring of organisms that reproduce sexually are not genetically identical to their parents because the offsprings inherited half of their total DNA from each parent.

Explanation: During sexual reproduction, offsprings are produced by a combination of genetic material from both parents. Each parent contributes half of the offspring's total DNA because during fertilization, a sperm cell from the father fuses with an egg from the mother to form a zygote which develops into an offspring.

A genetical identical offspring can only be produced from one parent through asexual means in which the offsprings inherits all of its total DNA from one parent and looks exactly like the parent. But in sexual reproduction, offsprings are not genetically identical to the parents because the offsprings are a combination of the genetic material from both parents.

Testing Two-Point Discrimination

yanalaym [24]

Two-point discrimination is the minimal distance which someone can perceive two different stimuli that given simultaneously. An area with higher receptor density will have a lower two-point discrimination result since the distance between receptor is lower.
The area that needs a high sensitivity like the palm of the <span>hands(especially the fingertips), face</span>, and tongue should be the one with lowest two-point discrimination.

In this report, a<span>nterior forearm two-point discrimination result is the lower than the fingertip. This result is suspicious since the forearm shouldn't more sensitive than the fingertip. Fingertip two-point discrimination is around 2-6mm and forearm should be much higher than 6mm.
