Independent grouping of qualities happens amid meiosis in eukaryotes. Meiosis could be a sort of cell division that diminishes the number of chromosomes in a parent cell by half to deliver four regenerative cells called gametes. In people, diploid cells contain 46 chromosomes, with 23 chromosomes acquired from the mother and a moment comparative set of 23 chromosomes acquired from the father. Sets of comparable chromosomes are called homologous chromosomes. Amid meiosis, the sets of homologous chromosome are separated in half to make haploid cells, and this partition, or grouping, of homologous chromosomes is arbitrary. This implies that all of the maternal chromosomes will not be isolated into one cell, whereas the all fatherly chromosomes are isolated into another. Instep, after meiosis happens, each haploid cell contains a blend of qualities from the organism's mother and father.

A person who has a recessive trait must have two<span> recessive alleles because - A dominant allele does not let a recessive trait show up, in other words it simply dominates and… over shadows the recessive trait.</span>
Answer:
b) opening calcium pores in the membrane
Explanation:
The opening of calcium ions channels facilitates the migration of vesicles containing neurotransmitters in the pre-synaptic neurons to the tip of the post-synaptic membrane. at the <u>neuromuscular junction </u>These neurotransmitters can either be <u>cholinergic or non-chorlinergic.</u> <u>At the tip of the pre-synaptic membranes the vesicles empty their neurotransmitter contents into the synapse.</u>
The neurotransmitters, diffuse through the neuromuscular junction to bind with the receptors on the <u>post-synaptic membrane on the post-synaptic neuron.</u> This stimulates opening of<u> ligand gated sodium ions,</u> and sodium ions diffuse into the post-synaptic neuronal membrane, to cause <u>depolarization</u>. if the stimulus is up to the threshold levels it generate action potential.
Therefore , more calcium ions channels opening produces; more diffusion of neurotransmitters;leading to opening of more sodium channels for depolarization; and IPSP or EPSP generation.
