Typically gender expression is heavily influenced by societal norms, but there are some traits that have been proven to be influenced my genetic makeup of males vs females. For example, girls tend to be drawn to more artistic expression because of the cone/rod ratio of their eyes, where as males have better perception of depth and speed, so they gravitate towards faster sports and race cars. Obviously this only has partial influence. Individuals have always ventured outside gender roles and norms. Some men express are in touch with their femininity and express it despite the stigma, and some women have more ‘male inclined’ personality traits. Of course, large political, philosophical, and religious movements have more impact, such as the feminist movement in the late 1960s-70s pushing females to act less in the traditional frame.
Answer:
It indicates that core histone genes were present in the last common ancestor of yeasts, plants, and animals
Explanation:
Histones are highly basic proteins that can strongly interact with DNA, which is packaged into nucleosomes, the basic structural and functional unit of chromatin. Each nucleosome is composed of approximately 147 base pairs of DNA wrapped around a core of eight histone proteins (two copies of four types of histones H3, H4, H2A, H2B). These core histones are evolutionarily conserved across eukaryotic kingdoms in terms of sequence and structure. Therefore, DNA-packaging into nucleosomes is considered a constraint for the evolution of core histones. Moreover, the presence of conserved core histones in eukaryotic kingdoms (e.g., yeast, plant, and animal kingdoms) is strong evidence that histone-mediated DNA packaging was presumably present in the last common ancestor of eukaryotic genomes.
