Answer: Option B
:
B
Syngamy is of 2 types endogamy and exogamy. Endogamy is self-fertilization, the gametes are from the same parent. For eg: tapeworm is bisexual and capable of self-fertilization.
Exogamy is cross fertilization, the gametes are from different parents. For eg: Rabbit isdioecious or unisexual animal.
Isogamy is when the fusing gametes are similar in morphology, that is shape, size and structure.
Anisogamy is when the fusing gametes are different in form, size and structure. Usually sexual reproduction is anisogamy.
