C. albicans is known to undergo a parasexual cycle involving heterothallic fusion of α and
a mating type cells followed by stochastic, concerted loss of chromosomes [44].

When Candida albicans
cells reproduce by
mating, they have two sex
types, «a» and «alpha».
Richard Bennett of Brown University in Providence, Rhode Island, and his colleagues mixed the two
types and saw
matings between same - sex
cells, but only a few (Nature, DOI: 10.1038 / nature08252).
These resultant haploid
cells can fuse with other haploid
cells of the opposite sex or
mating type during fertilization to create a new diploid
cell, or zygote.
But the vast majority of the
cells found in nature are of only one
mating type.
It describes how a population evolves from different
mating types producing same - sized sex
cells (or gametes) to
mating types producing different - sized gametes, such as where there are distinct males and females.
«Sexual reproduction does not require males and females, all it requires is the fusion of sex
cells from two different
mating types.»
When deprived of nitrogen, haploid
cells of opposite
mating types can fuse to become a diploid zygospore which forms a hard outer wall that protects it from adverse environmental conditions.
Sexual conjugation occurs when
cells starved for at least 2 hrs in a nutrient - depleted media encounter a
cell of complementary
mating type.
When a male germ - line chimera is
mated to a female germ - line chimera they will have three
types of offspring — pure band - tailed pigeons, band - tail - passenger pigeon hybrids, and when an engineered sperm meets an engineered egg
cell the result will be a fully formed de-extinct passenger pigeon.
