Homomorphic sex chromosomes: Where the X and Y (or Z and W) chromosomes exhibit few differences from each other in size and gene content, and are difficult or impossible to distinguish from karyotype data alone. Hermaphrodite: Male and female reproductive organs in the same individual. Male ...

When a female creates an egg or a male creates a sperm, the two strands of DNA must combine into a single strand. The sperm and egg from the mother and father each contribute one copy of each chromosome. They meet to give the new child two copies of each gene. To form the single ...
How do fish fins come into being and how do fins evolve into terrestrial tetrapod limbs? To answer this scientific question is substantially to understand how the genes that determine these traits are subject to natural and sexual selection, and how they thereby involve the innovation mechanics and...
Torties are almost always female (about99.96% of tortoiseshells are female) because the recessive gene for this trait is on the X chromosome, and cats need two genes to express this trait. Male torties are extremely rare but can happen if they have an extra X chromosome (XXY). Unfortunate...

451 Spanish-as-first-language speakers (265 male, 167 female,19 not reported) who varied from 18 to 63 years of age (M = 30.10, SD = 9.24) took part in the study. Participants resided in 14 different countries with the majority in Spain (159), Mexico (174), and Chile (...
