7 Questions
What is the difference between sexual and asexual reproduction in animals?
In sexual reproduction, the fusion of haploid gametes forms a diploid cell, while in asexual reproduction, new individuals are generated without the fusion of egg and sperm.
What are some examples of asexual reproduction in animals?
Some examples of asexual reproduction in animals include binary and multiple fission, budding of hydra, asexual reproduction by fragmentation, and parthenogenesis.
Which type of reproduction is extremely rare in vertebrates?
Parthenogenesis is extremely rare in vertebrates, but has been confirmed in a handful of sharks, snakes, lizards, and birds.
What is parthenogenesis and how can it be induced?
Parthenogenesis is a form of reproduction in which offspring develop from unfertilized eggs. It can be induced by environmental conditions or through artificial means by researchers.
What is the advantage of sexual reproduction in terms of genetic diversity?
Sexual reproduction increases genetic diversity through the shuffling and reshuffling of genes during meiosis and fertilization.
What is the role of hormones in controlling reproductive cycles in animals?
Hormones regulate reproductive cycles in animals by responding to environmental cues and controlling the secretion of other hormones. They ensure that animals reproduce only when sufficient energy sources are available and when environmental conditions favor the survival of offspring.
What is the difference between external fertilization and internal fertilization?
External fertilization occurs when the female releases eggs into the environment, where they are fertilized by the male. Internal fertilization occurs when sperm is deposited in or near the female reproductive tract and fertilizes eggs within the tract.
