In teleost fish, fertilization typically occurs externally, where eggs and sperm are released into the water. Following successful fertilization, embryonic development begins. The fertilized egg undergoes cleavage, forming a blastula, and then gastrulation, establishing germ layers. Organogenesis follows, shaping vital organs. Some teleosts exhibit different reproductive strategies, such as oviparity (laying eggs) or viviparity (live birth). Fish larvae hatch from eggs, entering various larval s...

Mammalogy Quizzes Ch. 23-24 Question 1 of 10 10.0 Points Why is dispersal male biased in polygamous species? A. Female philopatry is advantageous since females provide more parental care whereas males suffer from inbreeding and competition from philopatric behavior. B. Heterozygosity is increased with male philopatry which in turn increases female reproductive fitness. C. Males benefit from giving high level of parental care and females benefit from reduced resource competition. D. Male philopat...
