Pigeons may exhibit a checkered or plain color patterns. In a series of controlled mating the following data were obtained  F1 x F1 crosses  Checkered x plain. 34 checkered 0plain  Checkered x plain. 17 checkered 14 plain  Checkered x checkered 28 checkered 9 plain  Checkered x checkered 39 checkered 0plain    How are the checkered and plain patterns inherited ? Select and assigned symbols for the genes involved and determine the genotypes of the parents and offspring in each cross.

Angiosperm Reproduction

The process of sexual reproduction in flowering plants is known as angiosperm reproduction. In flowering plants, reproduction begins with pollination, or the transfer of male gametes (pollen) from the male reproductive organ (anther) to the female reproductive organ (pistil), and ends with fertilization of the female gametes (egg), which produces a zygote, which then grows to become a mature plant.
