Chemically-induced transmissible abnormalities in sperm-head shape.

The characteristics controlling sperm-head shape are carried on the autosomes. The effects on the progeny of alterations in this genome can be measured. Chemically-induced transmissible genetic damage in mice has been measured by assessment of the incidence of abnormal sperm among the progeny of CBA mice (of either sex) that have been treated with mutagens prior to mating with BALB/C mice.
