A mating between a purebred purple-flowered pea plant and a purebred white-flowered pea plant would produce a Hybrid.
In human genetics, assortative mating is a type of nonrandom mating in which pair connections are created based on phenotype (observable characteristics).
A statistical link between genotype and phenotype predicts a physical characteristic in a person or an anomaly in a patient with a specific mutation or a collection of mutations that are related to it.
The genotype of a purebred purple flowered pea plant will be PP
while the genotype of purebred white-flowered pea plant will be pp.
on crossing
PP X pp
Pp, Pp, Pp, Pp (offspring)
hence all the offspring produced will be hybrids.

Answer:
The main difference between lymphocytes and phagocytes is that lymphocytes generates specific immune responses against pathogens whereas phagocytes generate the same response to any pathogen.
Explanation:
This means lymphocytes are the tools of the adaptive immunity whereas phagocytes are the tools of innate immunity
The correct answer is: C) thoracolumbar region, and the postganglionic fibers secrete norepinephrine
The pathway of autonomic nervous system (sympathetic and parasympathetic) involves two:
1. Preganglionic neuron - from CNS (spinal cord or brain) to the autonomic ganglion, all of these fibers release acetylcholine (Ach)
2. Postganglionic neuron - from the autonomic ganglion to the cells of the effector organ, parasympathetic postganglionic fibers release acetylcholine while sympathetic postganglionic fibers release norepinephrine.
It depends on whether or not the parents are heterozygous for the trait. if they both are, then the child will have a 75% chance of having a widows peak.
It is the process in which an embryo, and later a fetus, develops and grows.
