Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders typically inherited. [2] The most common type is known as sickle cell anemia. [2] It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2] This leads to a rigid, sickle -like shape under ...
The distribution of haplogroup E1a lineages in Portugal was independent of the distribution of the younger and more ubiquitous E1b1a. [26] this distribution is consistent with a prehistoric migration from Africa to Iberia, possibly alongside mtDNA haplogroup U6. In Majorcans, Sub-Saharan Y-DNA lineage E-V38 was found at a total of 3.2% (2/62). [27]
The Malaria Atlas Project aims to map global levels of malaria, providing a way to determine the global spatial limits of the disease and to assess disease burden. [218] [219] This effort led to the publication of a map of P. falciparum endemicity in 2010 and an update in 2019. [220] [221] [222] As of 2021, 84 countries have endemic malaria. [17]
Genetics is the study of genes, genetic variation, and heredity in organisms. [1][2][3] It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically.
Derek Stefureac was having a normal day at work, talking to a colleague, when the first symptom appeared. “I felt some really intense numbness in my left foot,” Stefureac, 52, tells PEOPLE ...
Katy Perry is reflecting on her childhood with a whole new outlook.. As a guest on the Wednesday, Sept. 4 episode of Call Her Daddy, the musician, 39, opened up about her experience growing up ...
Mutations can involve the duplication of large sections of DNA, usually through genetic recombination. [ 10 ] These duplications are a major source of raw material for evolving new genes, with tens to hundreds of genes duplicated in animal genomes every million years. [ 11 ] Most genes belong to larger gene families of shared ancestry ...
Genetic studies on Croats. Population genetics is a scientific discipline which contributes to the examination of the human evolutionary and historical migrations. Particularly useful information is provided by the research of two uniparental markers within our genome, the Y-chromosome (Y-DNA) and mitochondrial DNA (mtDNA), as well as autosomal ...
