Answer: Mendel during his study on pea plants stated three laws of inheritance. These were: 1. Law of dominance: A dominant gene will express itself over the recessive gene. 2. Law of segregation: Parental genes are randomly separated to the germ cells such that each germ cell receives only one gene from each pair. 3.
By using this cross Mendel postulated Law of dominance and Law of Segregation. D.Dihybrid cross – Cross is made between a homozygous dominant parent to another homozygous recessive parent on the basis of twocharacters. By using this cross Mendel postulated Law of Independent assortment. So, the correct option is ‘Monohybrid cross’.
Explain law of Dominance. Law of Dominance states that dominant alleles always mask the recessive alleles. In heterozygous condition always dominant allele is expressed in F1 generation. The characters that appear in an F1 generation are called as dominant alleles and which are not expressed are recessive. For example, a cross between any pair ...
Solution: ∙ The Law of Dominance was given by Mendel. ∙ It states that - In a pair of contrasting characters (alleles) that are present together in an individual, one of them dominates or masks the effect of the other. ∙ For example, for height character T (tall) and t (dwarf) are two different alleles. ∙ When Tt are present together, T ...
Verified by Toppr. According to the law of dominance, a trait is represented by two contrasting factors of a gene in a heterozygous individual; the allele/factor that can express itself in a heterozygous individual is called as a dominant trait. The other factor whose effect is masked by the presence of dominant factor is called recessive factor.
State the principle of dominance with an illustration. Mendel proposed the laws of inheritance. The law of dominance states that whenever the dominant allele is present, the dominant allele will express itself. The expression of the recessive allele is suppressed in the presence of dominant allele. The recessive allele does not get lost.

This is correct if the genes are present on two different chromosomes. But if the genes are present on the same chromosomes, they may or may not show independent assortment, i.e. Linkage. Because of this reason, Law of independent assortment is not completely applicable. So, the correct option is ‘Law of Independent assortment’.
Law of Dominance; Law of Segregation; Principle of Independent Assortment; Know Some Terms. Gene – It is the basic unit of inheritance. It consists of a sequence of DNA, which is the genetic material. Genes can mutate and can take two or more alternative forms. Alleles – The alternative forms of genes. They affect the same characteristics ...
