When usingthe standard proteins it is typically assumed that the vv values of thestandard and actually measured protein are identical. With thisassumption, the ratio of the molecular masses of the two proteins isidentical to the ratio of their I(0)s normalized against the concen-trations.
The gametes (an egg and a sperm) fuse in the process of syngamy to form a 2 n zygote. The zygote divides mitotically to form a multicellular embryo ( embryogenesis), which is protected by either gametophytic tissues (such as remnants of archegonia in the nonseed land plants) or sporophytic tissues (the seed in the seed plants). An embryo,...
The endosperm nucleus develops into a mass of tissue (theendosperm), which surrounds the embryo. The outer layer of cells of the endospermis called the aleurone.A corn âseedâ is a fruit that consists of the embryo (2n), the endosperm (3n), andendosperm aleurone (3n), all enclosed in a pericarp (2n).The pericarp is a remnantof the pistil and is of maternal origin and genetics.n the corn your students will use, the pericarp is always colorless, butthe aleurone may be colorless or red. Although several genes interact in producingaleurone color, it is the C alleles that undergo segregation and recombination in theears that your students study.
