About 1:650–1000 children are born with an extra X or Y chromosome (47,XXX; 47,XXY; 47,XYY), which results in a sex chromosome trisomy (SCT). This international cross-sectional study was designed to investigate gaze towards faces and affect recognition during early life of children with ...
We empirically test whether the genetic system of sex determination has played a role in the evolution of exaggerated male ornaments in actinopterygiian fishes, a clade in which both female-heterogametic and male-heterogametic systems of sex determination have evolved multiple times. Using ...
Recent advances in nutritional ecology, particularly arising from Ecological Stoichiometry and the Geometric Framework for nutrition, have resulted in greater theoretical coherence and increasingly incisive empirical methodologies that in combination allow for the consideration of nutrient-related processes at man...
What would the sex chromosomes of a female with Turner Syndrome look like? a. XO b. XX c. XY d. XXY e. OY Symptoms of Turner's Syndrome: Females with Turner's syndrome are usually sterile with retarded sexual development, have a short stature, webli...
A sex-linked gene controlling the age at which the gonadotropic zone of the adenohypophysis differentiates and becomes physiologically active has been identified in the teleost Xiphophorus maculatus. Within the Belize stock, the factor P... KD Kallman,MP Schreibman - 《General & Comparative Endocrinol...
Cherry cells have 32 chromosomes. How many chromosomes does each of the daughter cells produced by mitosis have? How many chromosomes would be present at the various stages of mitosis? A 2n cell has 23 pairs of chromosomes. At the end of Meiosis 1, how many individual chromosomes will ...
The same mutation was found in the Y chromosomes of the proband's father, fertile paternal uncle, and two brothers (Fig. 12A). Such a DSD pedigree (unusual among Swyer families) suggests that the variant SRY allele is compatible with either male or female somatic phenotypes depending on ...
In genera of flowering plants that contain closely related gynodioecious and near dioecious species, near dioecy has probably evolved from gynodioecy by gradual reduction of seed set on hermaphrodites, caused by the action of several genes for partial female sterility. A literature survey shows tha...
We show that rates of plumage evolution are correlated between the sexes, but that sexual selection has a strong positive effect on male, but not female, interspecific divergence rates. Furthermore, we demonstrate that rapid male plumage divergence is biased towards carotenoid-based (red/yellow) ...
A gene that has more than one version is called a a. polymorphic gene b. genome c. zygote d. chromosome The 23rd pair of chromosomes, called {Blank} {Blank}, determines whether you will become a male or female. Which of the following words means ''colored body''? \\ a. gene b. ...
