representation of genotypes of a pair of contrasting traits of a character in the form of ratio is referred as genetic ratio. in this ratio the three different genotypes are represented- homozygous dominant genotype:heterozygote genotype:homozygous recessive genotype in case of a monohybrid cross ( either normal cross,reciprocal crosses of Mendel or back cross or test cross ratios) and for dihybrid crosses- dominant genotype:recombinant genotypes:recessive genotypes are represented. For instance monohybrid genotypic ratio is 1:2:1 and back cross/test cross ratio-1:1 For dihybrid genotypic ratio 1:2:2:4:1:2:1:2:1 It may differ in different cases according to T.H.Morgan.Bateson, punnet, Garrod etc.

What are the difference of mendelian genetics and non-mendelian genetics?
In Mendelian inheritance the allele has a one to one effect on the phenotype. A polygenic effect is given when many genes contribute in an additive fashion to the phenotype. Height is such and may have as many as eight genes contributing to the effect. Behavior is also of this type. Eye color is more Mendelian in nature.
Which is a mendelian trait?
A trait controlled by many genes
What is the difference between cytosplasmic and mendelian inheritance?
To make this simple cytoplasmic inheritance is the inheritance of genes in organelles such as mitochondria that do not go through regular mitosis which is Mendelian inheritance. It is a bit more complex than this and can be easily Googled.
What describes a Mendelian traits?
Mendelian traits are:simple single traits controlled entirely by one genecaused by a gene with simple dominant and recessive allele formsA Mendelian trait would not involve more than one gene, nor would it involve genes with more than two allele forms.
When two traits are on different chromosomes how are they inherited?
By mendelian genetics and Mendels law of segregation
What is the phenotype ratio for cross?
the phenotype ratio is the physical appearance
In what classic mendelian cross would you expect to find a ratio of 9 3 3 1 among f2 offspring?
dihybrid cross
When was Evolution in Mendelian Populations created?
Evolution in Mendelian Populations was created in 1931.
Why Mendelian laws are not applicable in crossing over?
Why Mendelian laws are not applicable in crossing over.

What is Mendelian inheritence?
Linkage
Does both mendelian and non-mendelian law applicable to prokaryotes?
Yes, both Mendelian and non-Mendelian laws are applicable to prokaryotes. Mendelian laws, such as the law of segregation and the law of independent assortment, describe the inheritance patterns of genes in prokaryotes similarly to how they do in eukaryotes. Non-Mendelian laws, such as incomplete dominance or co-dominance, can also be observed in prokaryotes. However, it is important to note that prokaryotes have different mechanisms of gene transfer, such as horizontal gene transfer, which can give rise to non-Mendelian inheritance patterns.
What is non-Mendelian inheritance?
Linkage
How many alleles are for a mendelian trait?
2
How many alleles are there for a Mendelian traits?
2
What kind of phenotype ratio would you expect from a mono-hybrid cross?
possible mendelian ratios for monohybrid cross genotype is 1:2:1 and phenotype is 3:1
What is the meaning of Mendelian?
Mendelian refers to the principles of genetics developed by Gregor Mendel in the 19th century. Mendelian genetics focuses on the inheritance of traits from parents to offspring through the passing of alleles. Mendel's work laid the foundation for the study of genetics.
