several quail factors, say, Q, 1 , Q,~, Q, :! and Q, 4 , of which q 1 is responsible for the 
lightest, and Q, 4 for the darkest normal and quail. 
1 3) Besides these genetic variations, there are considerable intrans- 
missible fluctuations in each subtype. 
14) The presence of P or the heterozygous condition of Q, may 
sometimes cause a reduction of "eyebrows" in the light normal and light quail, 
and gives rise to "specious plain" and "specious pale-quail." 
15) Light normal or quails (q' subtype) are often produced in crossing 
one of the or ft 4 type markings (darker normal, darker quail, striped, mori- 
caud) with one of the q type patterns (plain, pale-quail), a fact which is ex- 
plicable on the basis of multiple factor hypothesis. 
16) Moricaud und striped markings are also subject to variation within 
certain limits. 
17) There are various strains of the normal marking which differ from 
each other in minor points; these differences, though insignificant, are 
transmitted to the offspring. This fact shows that the so-called unit characters 
are not "unit" in strict sense but are comparable to chemical compounds ; 
modified strains may be compared with isomers or derivatives. 
18) Several heritable gradations of colour are distinguishable in yellow 
and green cocoons. These colour differences depend upon different genetic 
factors for various subtypes. 
19) Moulting character is highly variable according to environmental 
influences, and naturally there may exist many "specious" 3-moulters as well 
as "specious" 4-moulters which do not inherit their apparent or acquired 
characters to the offspring. 
20) In order to explain the unusual phenotypic ratios which are often 
met with in the inheritance of moulting character, I assumed two conditional 
factors, and i b , the simultaneous presence of which gives 3-moulters. Owing 
to the high variability of this character, the above assumption is still tentative. 
21) Mosaic of somatic characters does not necessarily accompany the 
mosaic of sexual characters, i. c. gynandromorphism.
