What is the difference between monohybrid crosses dihybrid crosses incomplete dominance multiple alleles sex linked genes and polygenetic inheritance?
Monohydbid crosses is the inheritance of a single allele or variation of a gene for example, pink or blue petal colour on a flower
monohybrid crosses is the inheritance of two alleles or variation of two genes on separate chromosomes for example, pink or blue petal colour on a flower AND tall or short stem of flower
incomplete dominance AKA codominance is when both alleles (variations of the characteristic) show equal dominace, for example a homozygous black cat would have the genotype BB, and a homozygous white cat would have the genotype WW, however a heterozygous cat with the genotype with BW would be grey as both characteristics would show.
multiple alleles is more than 2 characteristics of one gene for example A, B and O blookd grouping. this is usually discontinous variation.
Polygenic inheritance is when one characteristic is controlled by the alleles of 2 or more genes, for examply height. it is usually shown in continuous variation.

What experiment did mendel perform to test inheritance?
a. purebred crosses b. dihybrid crosses c. monohybrid crosses d. testcrosses (B)
Who discovered monohybrid and dihybrid crosses?
Monohybrid crosses were discovered by Gregor Mendel, an Austrian monk known as the father of modern genetics, in his famous pea plant experiments. Dihybrid crosses were also studied by Mendel in his experiments, where he observed the inheritance of two different traits simultaneously.
What is the importance of a 31 ratio in a monohybrid cross?
In a monohybrid cross, a 3:1 phenotypic ratio is significant because it reflects the inheritance pattern of a single trait governed by a dominant and a recessive allele. When two heterozygous parents (Tt) are crossed, the offspring exhibit three dominant phenotype individuals for every one recessive phenotype individual, illustrating Mendel's law of segregation. This ratio helps to confirm the principles of inheritance and predict the distribution of traits in future generations. Understanding this ratio is fundamental in genetics for predicting offspring traits and studying inheritance patterns.
Which of Mendel's laws cannot be observed in a monohybrid cross?
Mendelâ??s Law of Independent Assortment cannot be observed in a monohybrid cross. This is because you need to be able to observe two or more pairs of alleles in order to see this law in action as it describes how multiple pairs of alleles segregate independently of each other.
What is the difference between monohybrid and dihybrid crosses?
In monohybrid crosses, only one trait is considered, while in dihybrid crosses, two traits are considered simultaneously. Monohybrid crosses involve only one genetic locus, while dihybrid crosses involve two different genetic loci. The Punnett square for a monohybrid cross is a 2x2 grid, while for a dihybrid cross it is a 4x4 grid.
What is a cross called that involves one 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.
What is monohybrid inheritance?
Monohybrid inheritance is where an individual inherits a characteristic which is determined by a single gene with two alleles. For Example: coat color in specific mice is determined by one coat color gene with two alleles B ( black fur) and b ( for brown fur) As you can see one is dominant (B) and one is recessive (b).
What experiment did mendel perform to test inheritance?
a. purebred crosses b. dihybrid crosses c. monohybrid crosses d. testcrosses (B)
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.
A 1 to 2 to 1 phenotypic ratio in the F2 generation of a monohybrid cross is a sign o?
A 1 to 2 to 1 phenotypic ratio in the F2 generation of a monohybrid cross is a sign of incomplete dominance, where the heterozygous genotype results in an intermediate phenotype. This ratio is typical when one allele is not completely dominant over the other, leading to a blended or mixed phenotype in heterozygous individuals.

Monohybrid crosses were discovered by Gregor Mendel, an Austrian monk known as the father of modern genetics, in his famous pea plant experiments. Dihybrid crosses were also studied by Mendel in his experiments, where he observed the inheritance of two different traits simultaneously.

A cross that considers one pair of contrasting traits?
A monohybrid cross considers one pair of contrasting traits (or alleles) in an offspring resulting from the mating of individuals that differ in only one trait. This type of genetic cross allows predictions about the inheritance pattern of a specific trait based on the known genotypes of the parents.
A Cross is a cross that involves one pair of contrasting traits?
A monohybrid cross involves the inheritance of a single pair of contrasting traits, typically represented by alleles at a single gene locus. This type of cross helps determine the pattern of inheritance for particular traits in offspring.
What is the difference between a monohybrid and dihybird cross?
A monohybrid cross involves the study of one trait or gene, whereas a dihybrid cross involves the study of two traits or genes simultaneously. In a monohybrid cross, only one pair of alleles is considered, while in a dihybrid cross, two pairs of alleles are considered.
