This result gives you the probability that an offspring will have the dominant trait.
For example (2/4)*100 = 50, therefore there is a 50% probability of an offspring having brown hair. 4.
How do you find the probability of offspring using a Punnett square?Count the total number of boxes in your Punnett Square.
This gives you the total number of expected offspring. Divide the by. Multiply the number from step 4 by 100 to get your percent.
Thus, This result gives you the probability that an offspring will have the dominant trait.

Describe the purpose of cell differentiation in embryonic development.
Answer:
The differentiation of cells during embryogenesis is the key to cell, tissue, organ, and organism identity. Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation

Visceral reflex arcs differ from somatic in that ________. visceral arcs involve two motor neurons visceral arcs contain two sensory neurons visceral arcs do not use integration centers somatic arcs contain one additional component that visceral arcs do not possess
Visceral reflex arcs differ from somatic in that : ( A ) Visceral arcs involve two motor neurons
Visceral reflex arcsVisceral reflex arc is the reflex arc in the autonomic nervous system that produces non-skeletal muscular response in certain internal organs ( heart and blood vessels ). While somatic reflex arc is a neutral pathway which occurs from the sensing to response of stimulus.
Hence we can conclude that Visceral reflex arcs differ from somatic in that : ( A ) Visceral arcs involve two motor neurons.

What process do scientists think explains the evolution of mitochondria and chloroplasts from bacteria
Scientists put their conclusions into this by creating th Endosymbiotic theory. The endosymbiotic theory describes how mitochondria and chloroplasts (cell organelles) came to exist in eukaryotic organisms. The endosymbiotic theory explains the evolution of mitochondria and chloroplasts. Before mitochondria and chloroplasts were organelles in a cell, they were free prokaryotic cells that were absorbed by eukaryotic cells.
The mitochondrion was originally a prokaryotic cell that could undergo aerobic respiration. After being absorbed by a eukaryotic cell, it developed a symbiotic relationship with its host cell.
The chloroplast was originally a prokaryotic cell that could undergo photosynthesis (eg. cyanobacteria). Like the mitochondria, the photosynthesizing bacteria became dependent on the host cell after being engulfed.
There is much evidence to support the endosymbiotic theory.
Both prokaryotes and chloroplasts/mitochondria have circular DNABoth have their own ribosomesBoth divide through binary fission (splitting into two)Both have their own cell membranesWhat cell structure makes it possible for the internal environment of a cell to differ from the external
