What is the ratio of inhibitory factor?
What is the ratio of inhibitory factor?
Effect-of Inhibitory Factor (13: 3 Ratio): In this modification or gene interaction, one dominant factor inhibits or suppresses the phenotypic expression of another dominant gene found on different chromosome.
Which gene interaction has 15 1 ratio?

| 13:3 | Dominant and recessive epistasis |
| 9:6:1 | Duplicate interaction |
| 7:6:3 | No name |
What is the 3 1 ratio genetics?
A 3:1 Ratio is the relative fraction of phenotypes among progeny (offspring) results following mating between two heterozygotes, where each parent possesses one dominant allele (e.g., A) and one recessive allele (e.g., a) at the genetic locus in question—the resulting progeny on average consist of one AA genotype (A …
What is lethal gene f2 ratio and it was observed in which plant?
E. Baur (1907) discovered first case of lethal gene in plant, Snapdragon (Antirrhinum majus). In this plant, a yellow leaved dominant genotype called aurea when crossed with its own type (aurea × aurea), aurea heterozygous and normal green plant in 2: 1 ratio were obtained.
What is the ratio of supplementary gene?
9 : 3 : 4 ratio
(ii) Supplementary genes (9 : 3 : 4 ratio) : Supplementary genes are two independent pairs of dominant genes which interact in such a way that one dominant gene will produce its effect whether the other is present or not.
Which of the following ratio is an example of inhibitory gene interaction?
Inhibitory gene ratio. 1. 9:3:4.
What is the phenotype ratio of a cross between AaBb and AaBb in case of complementary gene?
In a dihybrid cross, F2 phenotypic ratio is 13 : 3.
Which of the following crosses will lead to a 9 3 3 1 ratio of phenotypes?
dihybrid cross
This 9:3:3:1 phenotypic ratio is the classic Mendelian ratio for a dihybrid cross in which the alleles of two different genes assort independently into gametes.
What is a 2 to 1 ratio?
A ratio of 2 to 1 simply means that for every 2 of something, there are 1 of something else, with a total of 3. In the box below, you can enter a number in either box and we will calculate the other number to keep the ratio of 2 to 1. In other words, we will calculate the corresponding equivalent ratio of 2:1 for you.
What is a 1 1 ratio in genetics?
A 1:1 ratio among progeny suggest one gene is involved in the phenotype which would involve a cross between a heterozygote X homozygote parent. 5. A 2:1 ratio among the progeny suggest one gene is involved where the presence of both recessive alleles results in death (ex: Aa x Aa) 6.
