## Overview

This repository contains supplementary tables for the article "Sexual size dimorphism is associated with gene family contractions in brain development in mammals" The study investigates gene family size expansions and contractions in relation to brain development and sexual size dimorphism in mammals, employing a comparative genomics approach. Subsequently, we perform a Gene Ontology (GO) enrichment analysis on the gene families experiencing expansion and contraction to uncover the functional significance of associated genes. Additionally, we conduct a gene expression analysis of genes linked to these families to determine their over expression in brain tissue, showing the potential influence of sexual selection on the mammalian brain.

## 概述

本仓库包含论文《哺乳动物性体型二态性与脑发育相关基因家族收缩的关联》的补充附表。本研究采用比较基因组学方法，探究哺乳动物脑发育相关基因家族的扩张与收缩情况，及其与性体型二态性的关联。随后，针对发生扩张与收缩的基因家族开展基因本体论（Gene Ontology，GO）富集分析，以揭示相关基因的功能意义。此外，本研究还对这些基因家族关联的基因进行基因表达分析，以确定其在脑组织中的过表达情况，从而阐明性选择对哺乳动物大脑的潜在影响。
