Mar 23/ 71. Limited Inheritance, after reading Wallace. —
If any tendency to transmit blue tint to ♂s alone, this wd be increased by selection by granting their descendants, who thus transmitted blueness in greater number. — But a similar tendency is requisite for each [illeg] variation in colour. — So when [action] to blue colour would be preserved, & the ♀ which inherited blueness wd be killed in greater number than other ♀s & then condition in which blueness was transmitted to ♂s alone wd be favoured.
It is possible that in all cases there may be so slight tending in a variation [arriving] in in one sex to be transmitted the same way ∴ & if so decided result wd be obtained; but I know of no evidence of this — & some facts opposed, as in case of which (Dr P. Lucas) characters are transmitted to opposite sex. —
the tendency to conserve, on the successive [c. 8 words illeg] some be eliminated. & that both sexes is the same colour
