Which one of the three types of life cycles of sexually reproducing organisms does not have a multicellular haploid stage?

Solutions

Expert Solution

The most common of the sexual life cycles: the diploid dominant.

This is the type of sexual life cycle that us humans have, also the majority of animals. Most part of the organism is multicellular, but the sexual cells, the gametes, are haploid and unicellular.

The other two cycles: the haploid dominant has mitosis after meiosis so there is a multicellular haploid organism in one of the stages; in the alternation of generations cycle, in one generation has a diploid multicellular organism and on the next an haploid multicellular organism.
