Abstract: | Standard mapping functions permit the calculation of map length from the frequency by which a chromosome segment has at least one chiasma. In interchange heterozygotes, approximately exact estimates of such frequencies can be obtained from the relative frequencies of specific groups of meiotic metaphase I configurations. Examples are given for two interchanges inSecale cereale. |
