Oogamy is the familiar form of sexual reproduction. Comment Anisogamy evolves from isogamy and oogamy evolves from anisogamy. In one type of anisogamy, both gametes can be flagellated and hence are motile. And not all species produce two different sizes of gametes. A bipolar mitotic spindle with a pair of centrioles … Hence, the differentiation of gametes helps to perform respective tasks. Isogamy is defined as a type of sexual reproduction that involves fusion gametes that are similar in size, morphology, and form. Figure 1: Isogamy Are the gametes of fucus isogamous or oogamous.
