In a monohybrid cross with one parent homozygous dominant and the other homozygous recessive
The phenotype of the F1 offspring will be 100% that of the parent with the dominant allele.
A cross of two of the F1 offspring will be 75% phenotypically like the dominant allele and 25% will be hommozygous recessive or 3 to 1

What is a monohybrid ratio?
A monohybrid ratio refers to the genotypic and phenotypic ratio seen in the offspring of a genetic cross involving only one trait. For example, in a monohybrid cross between two heterozygous individuals (Aa x Aa), the genotypic ratio among the offspring would be 1:2:1 for AA:Aa:aa, and the phenotypic ratio would be 3:1 for the dominant trait to the recessive trait.
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.
What is the phenotypic ratio for 121?
To determine the phenotypic ratio for a specific number like 121, more context is needed regarding the genetic cross or traits being studied. Typically, phenotypic ratios arise from specific genetic crosses, such as Mendelian inheritance patterns (e.g., a 3:1 ratio for a monohybrid cross). If you provide details about the traits and parental genotypes involved, I can help calculate the phenotypic ratio.
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 importance of a 9331 ratio in a monohybrid cross?
The phenotypic ratio expected from a monohybrid cross between heterozygotes is 3:1 (assuming complete dominance), with the genotypic ratio being 1:2:1. So, using tall = T, short = t and R = red, r = white as an example. A monohybrid cross of Tt X Tt would be expected to produce 3 tall plants and 1 short plant (phenotypic ratio 3:1), which would be 1 TT, 2 Tt and 1 tt (genotypic ratio 1:2:1). A dihybrid cross of heterozygotes is expected to produce a phenotypic ratio of 9:3:3:1. So the cross of TtRr X TtRr would be epected to have: 9 tall red, 3 tall white, 3 short red and 1 short white (phenotypic ratio) This is because each parent has 4 possible combinations of gametes (TR, Tr, tR and tr). There are therefore 16 combinations of gametes, providing a 9:3:3:1 phenotypic ratio. Both of these are probably best visualised using a punnett square (see link below).

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.
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 difference between monohybird cross and a dihybird cross?
A monohybrid cross involves the breeding of two organisms that differ in a single trait, focusing on the inheritance of one gene with two alleles. In contrast, a dihybrid cross examines the inheritance of two different traits, each governed by their own genes, typically involving four alleles. Monohybrid crosses yield a phenotypic ratio of 3:1 in the offspring, while dihybrid crosses typically result in a phenotypic ratio of 9:3:3:1. These crosses help illustrate Mendelian inheritance patterns in genetics.
What is the phenotypic ratio for a F1 cross?
The phenotypic ratio for a monohybrid cross in the F1 generation is typically 3:1. This means that three-quarters of the offspring will exhibit one phenotype, while one-quarter will exhibit a different phenotype. This ratio is based on Mendelian inheritance patterns.
What is the actual ratio of the phenotypic characteristics red 93 white 36?
The ratio of red to white phenotypic characteristics is approximately 93:36, which simplifies to 31:12 when divided by their greatest common factor of 3.
Conducting a monohybrid cross of F1 generation plants the recessive trait reappears in F2 plants in a ratio of . 11?
In a monohybrid cross, the F1 generation typically consists of heterozygous individuals displaying the dominant trait. When these F1 plants are crossed, the F2 generation exhibits a phenotypic ratio of approximately 3:1, with the dominant trait appearing three times for every one time the recessive trait appears. However, a ratio of 0.11 suggests a different observation, possibly indicating an unusual genetic interaction or a sampling error, as the expected ratio for recessive traits should be closer to 0.25 in a standard monohybrid cross.
What is a phenotypic ratio?
A ratio that shows the different outcomes you can get from a genetic cross.A ratio that shows the varied outcomes that results from a genetic cross and is based on physical appearance alone. For example yellow flowers, round seeds, brown hair, green eyes etc.The genetic make up of an organism is called genotype and the external appearance or expression of the genetic make up is called phenotype (Color, height, shape etc.). The ratio indicates the number of heterozygotes and homozygotes with reference to the genotypic ratio and to the number of phenotypes expressed as phenotypic ratio. The concept was given by Sir Gregor Johann Mendel, Father of Genetics who worked on pea plant with reference to 7 different characters. The result obtained for a cross between a single character is called monohybrid cross and the ratio is referred to as monohybrid ratio which is 1:2:1 for genotypic ratio and 3:1 for phenotypic ratio.in the dihybrid cross for the phenotypic ratio it is 9:3:3:1.
