the ratio of male and female gametes produced from their respective gametophytes in angiosperms is

Answer 1

Explanation:

The gametes are produced by the meiotic division. From a diploid, primary spermatocyte, four haploid spermatozoa are produced through meiosis. From a diploid primary oocyte, only one haploid ovum is formed. The remaining are polar bodies. These polar bodies do not develop as egg cell or ovum. Hence, the ratio between male gametes and female gametes produced from respective primary sex cells is 4 : 1.
