Answers
Answer:
(1) ans=the animals like dog can't be considered as hermaphrodite animal because A female pseudohermaphrodite has ovaries but male external genitalia, and for a male pseudohermaphrodite the reverse is true. These were in full agreement with our cases. The genital developmental disorders are caused by abnormalities of genetic or chromosomal origin, or inappropriate hormonal or chemical exposure.
(2) ans= Many fish, amphibians, and other sexual aquatic animals use external fertilization (the exceptions are aquatic mammals, sharks, and some other special types of fish). External fertilization is beneficial because the mother does not have to physically carry the developing offspring.
(3) ans=up
(4) ans=Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.
