explain the law of dominance
Answers
Answer:
Mendel's Law of Dominance can also be simply stated as: “In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype.

See. When ur.talking about law of dominance the always think of only 1 person's experiment that is Mendel’s experiment.
Law of Dominance
Mendel’s law of dominance states that:
“When parents with pure contrasting traits are crossed together, only one form of trait appears in the next generation. The hybrid offsprings will exhibit only the dominant trait in the phenotype.”
Law of dominance is known as the first law of inheritance. In this law, each character is controlled by distinct units called factors, which occur in pairs. If the pairs are heterozygous, one will always dominate the other.
Law of dominance explains that in a monohybrid cross between a pair of contrasting traits, only one parental character will be expressed in the F1 generation and both parental characters will be expressed in the F2 generation in the ratio 3:1.
The one which expressed in the F1 generation is called the dominant trait and the one which is suppressed is called recessive trait. In simple words, the law of dominance states that recessive traits are always dominated or masked by the dominant trait. This law can be described by Mendel’s experiment.
A monohybrid cross is a cross between the two monohybrid traits (TT and tt). Here plants which have the same characters but differ in only one character were crossed.
