Allometric genetics: mapping of gametophyte
gene Ga10
--Luiz Torres de Miranda and Luiz
Eugenio Coelho de Miranda
In MNL 49:71-73, J. Gonella and P. A. Peterson
reported linkages of A2, Bt and Ga10 but did not calculate
the recombination values of Ga10 with the other marker genes. Since
there are data between A2 and Bt with and without the presence
of Ga10 it occurred to us that it is possible to calculate linkages
with Ga10.
The values of A2 Bt linkage can
be calculated using the formula in MNL 61:32 and calculating the as
and bs from their Table
1, 46.41+a+b = 79.7 etc. to 2.81-a-b = 0.4 from a to d taken from data
with and without the presence of the gametophyte factor. This gives a value
of p = 0.048 near the 0.061 reported for data without Ga10.
We propose the model by least squares.
