Respuesta :
- A dihybrid cross between heterozygous individuals will result in exactly nine genotypes.
- Allele pairs do not influence one another during segregation for gamete formation.
- Gregor Mendel uncovered the basic principles of inheritance through his study on pea plants.
- He came to the conclusion that genes are inherited as distinct, paired units from each parent.
- Mendel observed how parental genes separated and if they showed up as dominant or recessive qualities in the children.
What does the first law of inheritance state?
Dominance Law
According to the law of dominance, only the phenotypic trait that is dominant will be passed on to hybrid offspring. Recessive characteristics are those alleles that are suppressed, whereas dominant traits are those alleles that control the trait.
What does the second law in inheritance state?
According to the law of independent assortment, during gamete development, a pair of characteristics segregates independently of another pair. Different qualities have an equal chance to occur together as the individual hereditary variables assort independently.
What does the third law of inheritance state?
According to Mendel's law of dominance, only one form of a trait will manifest in the offspring of two parents who have distinct, opposing qualities. The sole phenotypic trait that the hybrid offspring will display is the dominant trait. The first law of inheritance is known as the law of dominance.
