Around the mid-1850s, Mendel crossed true-breeding purple-flowered pea plants with true-breeding white-flowered pea plants. The results of his research provided us with the basic principles of heredity. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Not all terms will be used.

Respuesta :

Every gene is a sequence of DNA nucleotides located at a certain location along a chromosome.

Diploid cells have two sets of chromosomes, one from each parent and forming homologous pairs.

A chromosomal pair's homologs share the same genetic locus. As a result, in a diploid cell, each genetic location is represented twice.

The pure breed purple flowered plant's genotype will be PP. The pure breed white flowered plant's genotype will be pp. As a result, the dominant to recessive phenotypic ratio will be 1:0.

Mendel observed a dominant to recessive ratio of 3:1 when he set up a Parental (P) hybrid between true breeding purple and white flowered plants to develop the F1 and then allowed the F1 to self-pollinate to generate the F2.
