Fix this textHEREDITY
Fix this textby J. A. Thomson
Fix this textJohn Murray : 9s. net.
Fix this textThis is the second edition of an un-
Fix this textusually able book, in which the author,
Fix this textwith long labour and a rare power of
Fix this textreasoning, has surveyed the experiments
Fix this textand hypotheses of a thousand observers,
Fix this textand has reduced their acquirement to an
Fix this textorderly system of knowledge.
Fix this textIn Prof. Thomson’s definition, “here-
Fix this textdity” is not an entity, a force, or a prin-
Fix this textciple. It expresses a relationship; it is
Fix this texta lerm for the parent-and-offspring rela-
Fix this texttion between successive generations of
Fix this textliving organisms. He defines “inheri-
Fix this texttance" as the hereditary acquirement,
Fix this textincluding all that an organism is or has
Fix this textto start with in view of its hereditary
Fix this textrelation. Thus “heredity” is the link,
Fix this textor series of links, between successive
Fix this text‘‘inheritances.”
Fix this textA Standard Text Book
Fix this textProf. Thomson inquires how the par-
Fix this textent-and-child relation of heredity varies;
Fix this text)'h) it varies; how and why inheritance
Fix this textis altered by environment, by disease, by
Fix this texts fX He applies his conclusions to socio-
Fix this textlogy? and discusses the influence of indi-
Fix this textvidual heredity upon the inheritance of
Fix this textthe race. His work is designed for gene-
Fix this textral readers; it is clearly written, and
Fix this textappeals to every thoughtful person.
Fix this textHany pictorial illustrations in black and
Fix this textcolour are given. A bibliography of
Fix this textsuxty pages, with a useful subject index,
Fix this textis added for particular enquirers.
Fix this textIt is, of course, a commonplace that a
Fix this textcnld inherits the characters of its par-
Fix this textents; or, in the popular phrase, “like be-
Fix this textgets like. In the scientific phrase, like
Fix this texttends to beget like; since there is usually
Fix this text' a general correspondence between
Fix this textand other characters of a
Fix this textchild and the same characters in the par-
Fix this textent®' Parei Ts reproduce themselves with
Fix this texta difference.
Fix this textThis difference, in bisexual species,
Fix this textessentially is due to “the halving of the
Fix this textgerm-cells. In the microscopic examin-
Fix this texta ton of a living cell it is found that some
Fix this textpar ides take readily the staining colour
Fix this textt’set m making observations. These
Fix this textparticles are called chromosomes. It is
Fix this textan accepted fact of observation that the
Fix this textnuclei of the germ-cells which unite in
Fix this textfertilisation contain each one-half of the
Fix this textnumber of chromosomes contained in
Fix this textother cells of an organism.
Fix this text1 he chromosomes must be supposed to
Fix this textcontain some characteristic qualities of
Fix this textthe nuclei; and their numerical reduction
Fix this textin the germ-cells explains the varying
Fix this textinfluence of ancestry in heredity. Varia-
Fix this texttions of inheritance are due to’ the halv-
Fix this texting of the germ-cells, involving often a
Fix this textpreponderance of one parent and an ex-
Fix this texttrusion of characters due to another par-
Fix this textent. This part of the scientific explana-
Fix this texttion of heredity may be made clearer to
Fix this textgeneral readers.
Fix this textFactors in the Germ-cells
Fix this textIn the human species a paternal germ-
Fix this textcell X contains sixteen ‘‘chromosomes”
Fix this textor evident factors of character
Fix this textJOHN, JOHN, JOHN, JOHN, JOHN
Fix this textJOHN, JOHN. JOHN, John. John, John!
Fix this textJohn, John, John, John, John,
Fix this text1 hese. however, are not simple factors,
Fix this textbut represent a complicated inheritance
Fix this textfrom a number of ancestors. For in-
Fix this textstance. taking one step backward in here-
Fix this textdity, the factors may be
Fix this textJOHN, JOHN, JOHN, JOHN, John, John,
Fix this textJohn John,
Fix this textderived from one grandparent, and
Fix this textJane, Jane, Jane, Jane, Jane, Jane, Jane, Jane,
Fix this textderived from the other grandparent; so
Fix this textthat a representation of the sixteen char-
Fix this textacters in a paternal germ-cell might be
Fix this textmore truly
Fix this textJOHN, JOHN, JOHN, JOHN, John, John,
Fix this textJohn, John, Jane. Jane, Jane Jane, Jane,
Fix this textJane , Jane, Jane.
Fix this textEven this does not fully suggest the com-
Fix this textplication. since in heredity, though par-
Fix this textents exercise apparently a preponderating
Fix this textinfluence, the factors of inheritance may
Fix this textseemingly be varied to the limit of their
Fix this textnumber; so that a correct representation
Fix this textof the characters in a paternal germ-cell,
Fix this texthalf derived from the grandfather and
Fix this texthalf from the grandmother, might be on
Fix this textthe grandfather’s side
Fix this textJOHN, WILLIAM, SARAH, HENRY, Fred-
Fix this texterick, Agnf.s, Minnie, Clara,
Fix this textand on the grandmother’s side
Fix this textJane, Edward, Christopher, Hannah, Maud,
Fix this textThomas, Julius, Vera
Fix this text—since factors on the paternal side do
Fix this textnot necessarily represent male ancestors,
Fix this textand factors on the maternal side do not
Fix this textnecessarily represent female ancestors.
Fix this text1 hits a paternal germ-cell apparently
Fix this textmight have sixteen different factors

Fix this texterick, Agnes, Minnie, Clara, Jane, Edward,

Fix this textSimilarly a maternal germ-cell apparent-
Fix this textly might have been sixteen different
Fix this textfactors

Fix this textDREW, Susan, Mary, James, Matthew,
Fix this textWinifred, Ellen, Mark, Jessie, Dora, Paul,
Fix this textPeter, Cynthia.
Fix this textParental Characters Predominate
Fix this textAs a rule, it appears that the factors of
Fix this textthe parents predominate, so that an aver-
Fix this textage statement of ancestral characters in
Fix this texta paternal germ-cell might be
Fix this textJOHN, JOHN, JOHN, JOHN, Sarah,
Fix this textSarah, Henry, Frederick, Jane, Jane, Jane,
Fix this textJane, Edward, Edward, Christopher, Hannah
Fix this textAnd an average statement of ancestral
Fix this textcharacters in a maternal germ-cell might
Fix this textbe
Fix this textALBERT, ALBERT, ALBERT, ALBERT,
Fix this textCharles, Charles, Caroline, Andrew,
Fix this textWinifred, Winifred, Winifred, Winifred,
Fix this textEllen, Ellen, Mark, Jessie
Fix this textThe union of paternal and maternal
Fix this textgerm-cells on this plan would therefore
Fix this textresult in a son- or daughter-cell with
Fix this textthirty-two characters
Fix this textJohn, John, John, John, Sarah, Sarah, Henry,
Fix this textFrederick, Jane, Jane, Jane, Jane, Edward,
Fix this textEdward, Christopher, Hannah, Albert, Al-
Fix this textbert, Albert, Albert, Charles, Charles, Caro-
Fix this textline, Andrew, Winifred, Winifred, Winifred,
Fix this textWinifred, Ellen, Ellen, Mark, Jessie
Fix this textBut, since the species is apparently
Fix this textlimited to sixteen characters, the over-
Fix this textplus of sixteen characters is extruded in
Fix this textthe union of paternal and maternal germ-
Fix this textcells ; so that the resulting son- or daugh-
Fix this textter-cell contains only sixteen characters
Fix this textlike its predecessors. The extrusion is
Fix this texta fact, but the laws governing the ex-
Fix this texttrusion are not known. Hypothetically
Fix this textthere is a prepotency on the part of some
Fix this textfactors which issues in the elimination
Fix this textof other factors from the new cell. The
