概括
雄性和雌性黄蜂表现出与感官系统形态相关的独特行为. 斯科利亚 hirta 雌性拥有增强的嗅觉和振动感应来定位宿主,而雄性则改善了交配的视力.
科学领域:
- 昆虫学 昆虫学是一门学科.
- 动物行为 动物行为
- 感官生物学 感官生物学
背景情况:
- 在黄蜂 (Hymenoptera: Aculeata) 中,行为上的性二态是常见的.
- 感官系统的形态差异可能是这些行为区别的基础.
- 寄生虫黄蜂Scolia hirta捕食在土壤中的甲虫幼虫.
研究的目的:
- 为了研究感官系统形态学和Scolia hirta的性别特异性行为之间的联系.
- 测试一种假设,即行为差异是由形态二重形态支持的假设.
主要方法:
- 对男性和女性感官系统形态的比较分析.
- 用显微镜检查眼睛,眼球,眼膜和感官.
- 对天线和腿的形态评估.
主要成果:
- 雄性表现出增强的视觉系统 (更大的眼睛,眼球,更多的眼球) 来定位新出现的雌性.
- 雌性拥有更多和更大的感觉性斑点,这表明它们有先进的嗅觉能力来检测宿主.
- 雌性表现出形态适应 (粗的鞭毛体尖端,更宽的前骨),表明它们可以感知振动来定位地下宿主.
结论:
- 在Scolia hirta的感官系统形态是两形的,与明显的交配和寻找宿主行为相关联.
- 雄性依靠视觉来定位配偶,而雌性利用嗅觉和潜在的振动感应来发现宿主.
- 这些发现支持了这样一个假设:感官系统中的形态二态性驱动了黄蜂的行为分歧.

The Ratio of X Chromosome to Autosomes
9.9K
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...

Dosage Compensation

In animals, gender is determined by the number and type of sex chromosome. For example, human females have two X chromosomes, and males have one X and one Y chromosome, whereas C.elegans with one X chromosome is a male, and the one with two X chromosomes is a hermaphrodite.
In addition to sexual development, the X chromosome has genes involved in autosomal functions such as brain development and the immune system. Therefore, males and females with distinct numbers of X chromosomes will...
