- 遺伝学
背景:
- 人間の産科のジレンマは 胎児の大きな脳と 女性の骨盤との対立です
- このジレンマの先の経験的証拠は不確実だった.
研究 の 目的:
- 人間の骨盤の遺伝子構造を調べる
- 骨盤の形状と様々な健康問題との関係を調べる
- 人間の骨盤と脳の大きさの 共進化の証拠を 調べるためだ
主な方法:
- イギリスのバイオバンクから得られた 31,115個の二重エネルギーX線吸収計のスキャンで ディープラーニングを活用した.
- 7つの遺伝的骨盤現象と関連した 180の遺伝的位置を特定した.
- 性別特有の遺伝子構造と遺伝的相関を分析した.
主要な成果:
- 骨盤のフェノタイプは 性別特有の遺伝パターンを示しています
- 出産経路の大きさは 歩行が遅い 腰痛が少ないのに 股関節関節炎のリスクが高くなります
- 狭い出産経路は 骨盤底疾患のリスクを低下させますが 出産阻害のリスクは高まります
- 産経経と頭の幅の遺伝的相関は 共進化を示唆し 産科のジレンマを部分的に解決します
結論:

Synteny and Evolution
3.2K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral...

Human Genetics
485
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

Polygenic Traits
64.4K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Pleiotropy
38.3K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Incomplete Dominance
20.4K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Changes in the Appendicular Skeleton with Age
1.8K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
