Why does the expected genotype ratio often differ from expected phenotype ratio from a monohybrid cross?

This would be because phenotypes are the observable characteristics whilst genotypes are the actual genes. If we are given the genes: R (dominant) and r (recessive), and 2 organisms with Rr genes (one dominant and one recessive) produce offspring, their offspring will have one of the following genes, with the percentage chance in brackets: RR (25%)
Rr (50%)
rr (25%)
However, you can't detect recessive genes if a dominant gene is present, thus there will be no observable difference between the RR and Rr organism, besides for their offspring.
Thus, the phenotype is 75% and 25%, unlike for the genotype.

Why does the expected genotypic ratio often differ from the expected phenotypic ratio from monohybrid cross?
Because in heterozygotes, both alleles are transcribed and translated.
Is a Monohybrid Cross the same as a punnet square if not what's the difference?
A punnett square is the diagram used to determine the expected genotypic ratios for the offspring.A dihybrid cross is a cross involving two different traits. For example RrDd X RrDd would be a dihybrid cross. You could use a punnett square to determine the expected ratios for this cross:RDRdrDrdRDRRDDRRDdRrDDRrDdRdRRDdRRddRrDdRrddrDRrDDRrDdrrDDrrDdrdRrDdRrddrrDdrrddOne parent's genotype is shown across the top, the other down the side (both in bold).

How does genotype differ from serology?
Genotype is the complete genetic makeup of an organism.Serology, however is a group of techniques that are used to test for or identify specific genetic characteristics. Those characteristics are often called serotypes.For example:A person's blood type is a part of his/her genotype, and serologic testing can identify that person's serotype: A, AB, B, or O.Perhaps you were confusing "genotype" and "serotype"?

A cross that considers one pair of contrasting traits?
A dihybrid cross is the cross that involves parents that differ in two traits.
A cross that involves one pair of of contrasting traits?
A cross that involves one pair of contrasting traits is called Monohybrid A croos that involves parents that differ in two traits is a dihybrid cross
How does a monohybrid differ from a dihybrid with respect to allele pairs?
monohybrid is a cross between two heterozygous (Aa x Aa), they are usually controlled by different alleles of the same gene. A monohybrid cross compares only one trait. while Dihybrid is a cross between F1 offsprings of two individuals that differ in two traits. Dihybrid croos are often used to test for dominant and recessive genes in two separate characteristics.

What is the fold?
Fold line are organisms that produce offsprings of different GENOTYPE from their parents and differ among them. They contribute to SPECIES DIVERSITY.

What are individual versions of genes called?
Alleles I believe it is actually a monohybrid.
What term describes the parents in a mono-hybrid?
The term is: heterozygous parents A monohybrid cross involves a single parent, whereas a dihybrid cross. The law of segregation requires having two or more generations to describe.
