PLEASE HURRY Mendel's law of segregation states that only one of the two gene copies present in
an organism is distributed to each gamete (egg or sperm cell) that it makes, and that
the distribution of the alleles is random. According to Mendel's law of segregation,
which of the following letters is missing in the Punnett square at location X if a pea

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
