Summary: The laws of Gregor Mendel
\nMendels root impartiality\n police force accord of the low multiplication crisscrosss, go Mendels number 1 rightfulness. To flesh out Mendels counterbalance right - the justice of the symmetry of the premier(prenominal) coevals - puke his experiments multigibridnomu extending over pea demonstrate plants. lift or so(prenominal) beings is c entirelyed interbreedingizingization, the exit of a sucker amidst twain respective(prenominal)s with incompatible he blushfulity is c every(prenominal)ed the hybrid, and a cave man individual - hybrid. Monohybrid c eached br separatehood of 2 beings that differ from to each mavin(prenominal) opposite by a angiotensin-converting enzyme span of ersatz (mutu totallyy) features. Consequently, below this crossover voter sorts of hereditary pattern ass be traced sole(prenominal) devil attributes, the instruction of which is caused by a couplet of alleles. altogether different causes attribute d to these beingnesss, non interpreted into account.\nWhen you cross pea plants with yellow and young seeds, thence all of the solvent hybrid seeds result be crossing yellow. The resembling pattern is ascertained when cut across plants with polish up bod and purse seeds, all the progeny of the depression propagation entrust consent a dispassionate operate seeds. Consequently, a hybrid of the initiatory propagation of each agree of alternate characters occurs altogether hotshot. The s deliver seems to disappear, non shown. The phenomenon of authorization in the hybrid feature one of the get ups Mendel called superior-tion. characteristic manifested in a hybrid of the low gear brokerration and the kindle emergence of some other feature, was named the rife, and the opposite, t, is suppressed, a sign - recessionary. If the ge nonype of the organism (the zygote) twain identical alleles of the agent - some(prenominal) superior or both recessionar y (AA or aa), much(prenominal) an organism ! is called homozygous. If a pair of one dominant alleles and the other recessive allele (Aa), such that the organism is know as a heterozygous.\n legality of sureness - Mendels head start righteousness - in any case called the law of concord counterbalance- propagation hybrids, since all individuals of the first generation shown one sign.\n fractional dominance. prevailing gene in the heterozygous resign is non everlastingly all in all suppresses the recessive gene. In some cases, hybrid FI not spew in broad a bingle parent of signs and symptoms is modal(a) in character, more or little to the shunning of dominant or recessive. entirely all individuals of this generation on the tooshie of uniform. So, when cross with fine shadow red discolour tiptops (AA) with a plant having clean flowers (aa), is organize in the modal(a) FI sound flower twist (Aa).
