Identify the gametes in the figures A, B and C.
Open in App
Solution
The correct option is C A - Isogametes,
B - Heterogametes,
C - Heterogametes
The gametes which are identical in morphology and indistinguishable from each other are known as homogametes or isogametes. Those gametes which differ morphologically to an extent that they are distinguishable and can also be categorised into male and female gametes are known as heterogametes.
- A - Clearly indicates that those are homogametes or isogametes because both gametes are identical.
- B - Clearly indicates that those are not homogametes because there is much size difference between the male and female gametes. Hence, those are heterogametes.
- C - Indicates the two well defined gametes which are not similar, i.e., ovum (female) and sperm (male). Hence, these are also heterogametes.
