The genotype is the actual code for a trait. Hidden on the chromosome we can never actually see the alleles controlling the trait unless we sequence the DNA. The phenotype is the result of at least two alleles expressing a visible or measurable trait in an individual. A genotype to phenotype ratio is the correspondence between the unseen code of the individual's alleles and the detectable quality of the individual's trait. This ratio relates the proportional quantities of unseen and seen, a comparison between the encoded trait and the expressed result of the code.

What is the phenotype ratio of GgTT X ggTt?

The phenotype ratio of GgTT X ggTt is 1:1. This cross involves genes segregating independently, leading to one genotype (GgTt) that shows the dominant phenotype and one genotype (ggTT) that shows the recessive phenotype.


What are the genotype and phenotype ratios in offspring from two heterozygous parents?

The genotype ratio is 1:2:1 (1 homozygous dominant, 2 heterozygous, 1 homozygous recessive) and the phenotype ratio is 3:1 (3 individuals showing the dominant trait, 1 individual showing the recessive trait).


When crossing a Rr genotype with a rr genotype what will the ratio of RR to rr be in the resulting generation?

The resulting generation will have a 1:1 ratio of RR to rr genotypes when crossing an Rr genotype with a rr genotype, as each parent will contribute one allele to the offspring.


What is the phenotype ratio of a cross between a heterozygous male and female?

The phenotype ratio will depend on the specific genetic traits being studied. In general, a cross between two heterozygous individuals is expected to result in a 3:1 phenotypic ratio, with three-quarters of the offspring displaying the dominant phenotype and one-quarter displaying the recessive phenotype.


What is the expected phenotype ratio of seed color of the offspring of an F1 x F1 cross?

The expected phenotype ratio of seed color in the offspring of an F1 x F1 cross is 3:1. This is because the F1 generation is heterozygous for the trait, resulting in a 3:1 ratio of dominant to recessive phenotypes in the offspring.

What would be the phenotype ratio and genotype ratio in the offesprings in the f2 generation?

For monohybrid cross the genotype ratio in f2 generation would be 1:2:1 and phenotype ratio would be 3: 1


What is the genotype and phenotype ratios for a homozygous dominant female and a homozygous resessive male?

When a homozygous dominant female (genotype AA) is crossed with a homozygous recessive male (genotype aa), all offspring will inherit one dominant allele from the mother and one recessive allele from the father, resulting in a genotype of Aa for all offspring. The phenotype ratio will show all offspring displaying the dominant trait. Thus, the genotype ratio is 100% Aa, and the phenotype ratio is 100% expressing the dominant trait.


What is the phenotype ratio of GgTT X ggTt?

The phenotype ratio of GgTT X ggTt is 1:1. This cross involves genes segregating independently, leading to one genotype (GgTt) that shows the dominant phenotype and one genotype (ggTT) that shows the recessive phenotype.


What is the genotype and phenotype of homozygous?

Are you talking about phenotype or genotype? Phenotype is the expression of the genotype. Genotype is what you inherited. Phenotype is what you see. Homozygous is the same. Heterozygous is different. If you inherit one allele for blue eyes and one allele for brown eyes, your phenotype should be brown eyes. Your genotype would be brown eyes, blue eyes. You would have a heterozygous genotype.


What are the genotype and phenotype ratios in offspring from two heterozygous parents?

What is the ratio produced if Tt is crossed with tt?

The ratio produced if Tt is crossed with tt is 1:1 for the genotype and 1:1 for the phenotype. This is because all the offspring will inherit a recessive allele from the tt parent, resulting in all of them having the same genotype and phenotype.

The expected phenotype ratio of seed color in the offspring of an F1 x F1 cross is 3:1. This is because the F1 generation is heterozygous for the trait, resulting in a 3:1 ratio of dominant to recessive phenotypes in the offspring.


What is geneotype?

Genotype versus Phenotype Genotype is your specific gene for a certain Trait. lets say B was for Tall gene and b is for small gene. your Genotype to Tall could be BB or Bb your gentype for small will be bb. Phenotype is what is the physical Appearance evne though the Genotpe has one gene that codes for big and one that codes for small for example (Bb) the physical appearnce is Tall.


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.


To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is?

To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is homozygous recessive. A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotype ratio is 3 dominant 1 recessive.
