CAN SEXUAL SELECTION DRIVE THE EVOLUTION OF SPERM CELL STRUCTURE?

Can Sexual Selection Drive the Evolution of Sperm Cell Structure?

Sperm cells have undergone an extraordinarily divergent evolution among metazoan animals.Parker recognized that because female animals frequently mate with more than one male, sexual selection would continue after mating and impose strong selection on sperm cells to maximize fertilization success.Comparative analyses among species have revealed a g

Speaker Identification Using a Convolutional Neural Network

Speech, a mode of communication between humans and machines, has various applications, including biometric systems for identifying people have access to secure systems.Feature extraction is an important factor in speech recognition with high accuracy.Therefore, we implemented a spectrogram, which is a pictorial representation of speech in terms of

Assessment of heterotic potential of indica rice hybrids derived from KMR 3/O. rufipogon introgression lines as restorers

Present investigation was carried out to assess the heterotic yield potential of 162 indica rice hybrids derived from twenty six KMR3/O.rufipogon introgression lines (ILs) and six cytoplasmic male sterile (CMS) lines.The derived hybrids and testers were phenotyped for days to 50% flowering, plant height, number of productive tillers and yield per p

An in vitro-identified high-affinity nucleosome-positioning signal is capable of transiently positioning a nucleosome in vivo

Abstract Background The physiological function of eukaryotic DNA occurs in the context of nucleosomal arrays that can expose or obscure defined segments of the genome.Certain DNA sequences are capable of strongly positioning a nucleosome in Toothpaste vitro, suggesting the possibility that favorable intrinsic signals might reproducibly structure ch
