Which is the example of inhibitory gene?
Which is the example of inhibitory gene?
Example of inhibitory gene is pigmentation in rice plants. In rice plants the presence of gene ‘P’ is responsible for deep purple leaves. But if a gene ‘I’ is present then the expression of purple leaf colour is inhibited and the leaf becomes normal green.
Which of the following ratio is an example of inhibitory gene interaction?
Inhibitory gene ratio. 1. 9:3:4.
What is Psudoallele Mcq?
c) Alleles with similar function and structure. d) Alleles with similar function and different structure. Explanation: When two types of allele have similar functions but different structures, it is called pseudoallele.
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.
What are inhibitory genes?
A gene that prevents the expression of another gene.
What are the two types of gene interaction give their examples?
There are 8 main different types of gene interaction:
- The interaction between Dominant factors.
- Complementary factors.
- Supplementary factor.
- Epistasis.
- Effect of Inhibitory factor.
- Duplicate factors.
- Multiple factors or Polygenic Inheritance.
- Lethal factor.
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 ratio shows gene suppression effect?
This type of epistasis is sometimes called dominant suppression, because the deviation from 9:3:3:1 is caused by a single allele that produces a dominant phenotype, and the action of this allele is to suppress the expression of some other gene….
Proportion | Genotype | Phenotype |
---|---|---|
1/16 | rryy | Wrinkled, green |
Who is known as Father of Genetics?
Gregor Mendel. Gregor Mendel’s work in pea led to our understanding of the foundational principles of inheritance. The Father of Genetics.
Who is known as the Father of Genetics Mcq?
Gregor Johann Mendel
Gregor Johann Mendel is known as a “Father of modern genetics” for his pioneering work in the field of genetics. He gave three laws of inheritance, viz. Law of dominance, Law of segregation and Law of independent assortment.
What are the two types of gene interactions?
What is ratio of inhibitory epistasis?
The ratio is 12:3:1. An example of dominant epistasis is found for fruit colour respectively, white, yellow and green.
