Brachycephaly (derived from the Ancient Greek βραχύς, 'short' and κεφαλή, 'head') is the shape of a skull shorter than average in its species.It is perceived as a cosmetically desirable trait in some domesticated dog and cat breeds, notably the pug and Persian, and can be normal or abnormal in other animal species.
Cytoplasmic–genetic male sterility systems are widely exploited in crop plants for hybrid breeding, and for maintaining hybrid lines, due to the convenience of controlling sterility expression by manipulating the gene–cytoplasm combinations in any selected genotype. Incorporation of these systems for male sterility evades the need for ...
Jewish populations, and particularly the large Ashkenazi Jewish population, are ideal for such research studies, because they exhibit a high degree of endogamy, and at the same time are a large group. Jewish populations are overwhelmingly urban and are concentrated near biomedical centers where such research has been carried out.
Marker assisted selection or marker aided selection (MAS) is an indirect selection process where a trait of interest is selected based on a marker (morphological, biochemical or DNA/RNA variation) linked to a trait of interest (e.g. productivity, disease resistance, abiotic stress tolerance, and quality), rather than on the trait itself.
New Hampshire lawmakers state in House Bill 1102 that birth defects and deformities like brachycephaly, or intentional breeding of animals with these defects, causes hardships in dogs' lives.
DNA shuffling by molecular breeding was first reported in 1994 by Willem P.C. Stemmer. [1] [7] He started by fragmenting the β-lactamase gene that had been amplified with the polymerase chain reaction (PCR) by using DNase I, which randomly cleaves DNA.
Somatic cell nuclear transfer can create clones for both reproductive and therapeutic purposes. In genetics and developmental biology, somatic cell nuclear transfer (SCNT) is a laboratory strategy for creating a viable embryo from a body cell and an egg cell.
The English bulldog, a typically brachycephalic dog breed, may have brachycephalic syndrome. A Peke-face Exotic shorthair.. Brachycephalic obstructive airway syndrome (BOAS), also known as brachycephalic airway obstructive syndrome (BAOS), brachycephalic airway syndrome (BAS), and brachycephalic syndrome (BS), [1] is a pathological condition affecting short nosed dogs and cats which can lead ...
