in a 3-point cross, crossovers that occur during the formation of which gametes can be scored using the phenotype of f2 progeny?
JulsSmile [24]

In gametes generated by F1 tri-hybrids and gametes produced by parents from true-breeding populations.

When non-sister chromatids of homologous chromosomes exchange genetic material during meiosis, novel allelic combinations are created in the daughter cells. The locations of three genes in the genome of an organism are identified using a three-point cross. A homozygous recessive individual is crossed with a person who is heterozygous for three mutations, and the progeny's phenotypes are graded. When F1 progeny are self-pollinated, a 3:1 ratio of F2 progeny are created.

9966 [12]

Answer:

The first stage of neural communication, <u>conduction</u>, is the movement of the signal within a single neuron. <u>Transmission</u> is the movement of a signal between neurons.

Explanation:

The neuron is the irreplaceable and highly specialized unit of the Nervous System, since it is the basic element in the conduction of the nerve impulse. The primary function of the neuron, conceived in its uniqueness, is to receive information and transmit it, once it has been processed.

The nerve impulse only spreads in one direction. When a neuron is stimulated, electrical changes originate that begin in the dendrites, pass through the neuronal body, and end in the axon, this is known as conduction. At the point where an axon and a dendrite are associated, it plays a very important role in the transmission of the impulse from one neuron to another and in the functioning and coordination of the nervous system in general, since the neurons do not act in isolation. The neurons are arranged in such a way that the axon endings of one are connected with the dendrites of the next neuron, but there is no physical contact itself, but a microscopic space that separates them, in addition there is a neurotransmitter substance that allows the flow of nerve impulse under those conditions, said substance is acetylcholine. These transmitting molecules diffuse through the synaptic cleft and chemically transfer the signal, from the axon of a neuron to the receptor neuron.
