To solve the question regarding which organism has male and female gametophytes that are independent and free-living, we can follow these steps:1. Understand the Terms: - Male and female gametophytes are the structures that
Let’s see. So far I had three male and five female dogs in my life. Each and every single one was unique and gave me different challenges. Without counting the two females who had to endure terrible abuse in their lifetimes and therefore had to be slowly rehablitiated, I would say t...
On this basis, each sighted group was characterised by its size, its composition (classified as mixed-sex, all-male or all-female according to the sex of the adults that composed it), and by the activity synchrony of its members (simply classified as ‘synchrony’ when all the deer were ...

While young male chimps pass their time playing, young female chimps carefully study their mothers...
By analogy to female moth biosynthesis, the presence of alcohol and aldehyde (the latter presumably being derivative of 16:OH) as functional groups in B. anynana male compounds suggests that reduction must occur; yet the involved molecular players could have distinct origins compared with the genes...

The studied determinants comprised local-scale factors that can be managed by individual growers: tree cultivar, distance between apple trees and forest, and presence of ants. The studied parasitoid characteristics were sex ratio, body size and emergence time. Parasitoid sex ratio, in general female...
