#19

Dy aneup, rererreu 19) Refer to the following figure: tal generation crosses possible outcomes in fertilization OOOO F, generation In his experiments, Mendel began with true-breeding parental (P) plants. What results did he see when he cross-fertilized P generation plants that had different traits? 20) If an individual has genotype AaBi, how many different gametes can he or she produce? What combinations of alleles are possible?

Answer 1

19)Mendel crossed true-breeding parents, in the image the seed clour trait is shown, the yellow is dominant to green, the F1 progeny obtained by crossing two true-breeding parents shows the dominant trait, all the F1 progenies are Yy ( given in the image, YY-yellow parent, yy-green parent YY *yy the genotype of the progenies is Yy) since F1 progenies have the dominant allele it shows dominant trait.

so the F1 progeny obtained by the crossing of parental plants with different traits shows the traits of one parent ( dominant parent).
