Question

In mice, amutation called brachyury is trasmitted in anautosomal dominant fashion. The phenotype conferred by thismutation is a shortened tail. Thus, the symbol for brachyury is T.A cross between short tailed female mice (T/+) and short tailedmale mice (T/+) produces two phenotypic classes: Normal tailed miceand short tailed mice. Over the course of several months, thiscross produces 61 short tailed mice and 32 normal tailed mice. Givethe likely genotypes and genotypic ratio for theseoffspring.
