what is dihybrid Cross
Answers
Explanation:
Dihybrid cross is a cross between two different lines/genes that differ in two observed traits. We compare two different characteristics in a dihybrid cross. Its phenotypic ratio is 9:3:3:1, where 9 plants have all dominant characteristics and 1 plant has all recessive characteristic.
Answer:
A dihybrid cross describes a mating experiment between two organisms that are identically hybrid for two traits. A hybrid organism is one that is heterozygous, which means that is carries two different alleles at a particular genetic position, or locus. Therefore, a dihybrid organism is one that is heterozygous at two different genetic loci. In 1865, Gregor Mendel performed dihybrid crosses on pea plants and discovered a fundamental law of genetics called the Law of Independent Assortment. Mendel began his experiments by first crossing two homozygous parental organisms that differed with respect to two traits. An organism that is homozygous for a specific trait carries two identical alleles at a particular genetic locus.
