Monohybrid - A genetic cross made to examine the distribution of one specific set of alleles in the resulting offspring
Example: tall peas x short peas or TT x tt
Dihybrid - Hybridization using two traits with two alleles each.
Example: tall peas with round seeds x short peas with wrinkled seeds or TTRR x ttrr
Mendel's Mono Hybrid Cross: * it involves 1 characteristic like tallness and shortness. * 2nd step is to self pollinate the tall plant(TT) and pure short plant(tt) *now we'll get the first filial generation where we hv (TT) -pure tall(1) , (Tt)-hybrid(2) and (tt) - pure short(1)Mendel's Dihybrid Cross : * it involves 2 diff characters like tall plant with round seed and short plant with wrinkled seeds. *when we self pollinate the tall and round (TT)(RR) with the short and wrinkled with(tt)(rr) , we'll get the f1 or first filial generation. *the f1 generation has tall with round(TT)(RR)-(9) , short with wrinkled(tt)(rr)-(1) and hybrid (Tt)(Rr)-(6) * the ratio is 9:3:3:1.
A mono-hybrid cross occurs when each parent has a different allele for the same trait, as in tall (T) and short (t) for height. This results in the 1:2:1 or 1TT:2Tt:1tt genotypic segregation ratio in the F2 if the offspring is allowed to self. A di-hybrid results when each parent differs from the other for alleles of two traits. If a di-hybrid F1 is allowed to self, the normal genotypic ratio in the F2 population will be 9:3:3:1, or 9AABB:3A_bb:3aaB_:1aabb.

A monohybrid cross is the breeding of two organisms, each of which is homozygous for different phenotypes a particular, for example, male fruit fly who is homozygous for long wings (genotype LL) being crossed with a female who is homozygous for dumpy wings (DD). All the offspring will be heterozygous (LD), but will display the phenotype of the dominant trait. A dihybrid cross is a cross of two heterozygous individuals; in a dihybrid cross, there is a 25% chance that any given individual offspring will be homozygous for the dominant trait, a 50% chance that it will be heterozygous, and a 25% chance that it will be homozygous for the recessive trait.
It is a dihybrid cross.An example: if you cross garden peas having round yellow seeds with others having wrinkled green seeds, that is a dihybrid cross, because you are tracking both seed shape and seed color.
A dihybrid cross is the cross that involves parents that differ in two traits.
That would be a dihybrid cross! =D got it right on a quiz!
monohybrid cross deals with one genotypic trait whereas the dihybrid cross deals with two traits being crossed to see the possible genotypes.
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

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.
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.

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).

"Mono"- One. One trait from each parent In a Dihybrid Cross it's two traits from each parent.
