摘要:
H-W (H-Y) antigen was investigated in diploid, triploid, and tetraploid Xenopus hybrids. These hybrids differ from each other with respect to their sex chromosome constitution–they all have a single W chromosome but one to three Z chromosomes. The H-W antigen concentration is reduced with increasing numbers of Z chromosomes. In the diploid and triploid hybrids the single W chromosome is able to guarantee ovary development, but among the tetraploids both male and female animals occur. However, both sexes have identical H-W antigen titers in the somatic tissues. It can be concluded that in these tetraploid hybrids with a ZZZW sex chromosome complement, the amount of H-W antigen is too low to sustain ovary development in all case
