In all the examples I can think of, (mostly vertebrate), female meiosis, or oogenesis, only haploid gamete is produced while the other cell divisions result in polar bodies. While male meiosis results in 4 haploid gametes. This difference follows the fundamental definition of female and males being defined as resources committed into reproductive cells.
I want to know if this asymmetrical gamete production is truly universal across all organisms. Are all meiosis in plants or unicellular organisms unequal between male and female?
