II. Vererbung der von den Chromosomenzahlen unabhängigen morphologischen Eigenschaften bei der Verbindung Triticum polonicum×T. speltaSEIJI MATSUMUR1936 Volume 12 Issue 6 Pages 289-306

JOURNAL FREE ACCESS1. Die Merkmale Begrannung, Knoten- und Spelzenbehaarung sowie Spelzenlänge werden unabhängig von den Chromosomenzahlen vererbt. Die sie bedingenden Erbanlagen müssen demnach in einem der Genompaare AA und BB liegen.
2. Alle diese Merkmale zeigen monohybriden Erbgang.
3. Nur die Faktoren für Begrannung und Knotenbehaarung sind gekoppelt; der Austauschwert beträgt ungefähr 28.5%.
4. Der Faktor für Spelzenlänge P übt auf die Entwicklung von Begrannung und Behaarung einen hemmenden Einfluss aus.View full abstractDownload PDF (1739K) -

JOURNAL FREE ACCESSThe lady-bird beetle, Harmonia axyridis PALLAS is a highly variable species. The author experimented on the inheritance of the color pattern and also on that of the presence and absence of a transverse ridge on the elytra.
The elytral color patterns may be classified into six types as follows:
1. s type (succinea)-(Fig. 1-a, b, c)
2. A type (aulica)-(Fig. 1-d, e)
3. S type (spectabilis)-(S1 subtype-Fig. 1-f. S2 subtype-Fig. 1-g)
4. AS type-(Fig. 1-h, i)
5. C type (conspicua)-(C1 subtype-Fig. 1-j. C2 subtype-Fig. 1-k)
6. AC type-(Fig. 1-l, m)
Each of s, A, S and C types is determined by a factor which shows inheritance as follows:
1. s is largely recessive to any of the other types.
2. AS is the hybrid between A and S.
3. AC is the hybrid between A and C.
4. S is a simple recessive to C.
5. The subtype S1 is the homozygote, while the subtype S2 is the heterozygote of S and s. The subtype C1 is the homozygote or the heterozygote of C and S, while the subtype C2 is the heterozygote of C and s.
Genes p, PA, PS, and PC which determine the appearance of s, A, S and C respectively constitute a set of quadruple allelomorphs and are autosomal.
Hence, genic constitution of the six phenotypes may be designated follows:
s type-pp
A type-PAPA, PAp
S type-S1 subtype-PSpS,
S2 subtype-PSp.
AS type-PAPS.
C type-C1 subtype-PCPC or PCPS
C2 subtype-PCP.
AC type-PAPC.
Tan and Li's interpretation (Amer. Nat. 1934, 68: p 252-265) on the inheritance of pattern types of the same beetle which is based on mutually independent genes seems inadequate.
The presence (Fig. 2-a) or absence (Fig. 2-b) of a ridge on the elytra is also inherited on the monohybrid basis.
The factor (R.) for presence is dominant to the factor (r.) for absence.View full abstractDownload PDF (492K) -

JOURNAL FREE ACCESS1. In Punica granata L. and P. granata var. nana PERS. three pairs of genes, Cc, Ss, and Rr, concerning flower colours were determined. R produces red flower when S and C are also present; S produces salmon pink flower in the presence of C, while C by itself does not produce any colour.
2. 8 gemini were found in the PMC of Punice granata L. and P. granata var nana PERS. The meiosis is normal so that the pollen grain nucleus contains 8 chromosomes.View full abstractDownload PDF (174K) -
