How is a recessive allele different from a dominant allele apex?

2 answers:

For the trait that is coded by a recessive allele to be expressed, the must be homology, which means that an offspring has to inherit that recessive allele from both its parents.

A dominant allele will dominate over the recessive allele, so for the trait coded by a dominant allele to be expressed, the offspring only needs to inherit the allele from one of its parents.

For example: "R" is brown eyes, "r" is blue eyes.
Now you get one R from each of your parents.
RR (homozygote) = brown eyes
Rr (heterozygote) = brown eyes
rr (homozygote) = blue eyes

Where are the sensory neurons located in the reflex arc?

Wewaii [24]

<span>Most reflex arcs involve only three neurons. The stimulus, such as a needle stick, stimulates the pain receptors of the skin, which initiate an impulse in a sensory neuron. This travels to the spinal cord where it passes, by means of a synapse, to a connecting neuron called the relay neuron situated in the spinal cord.</span>
