2. which is better method of reproduction sexual & asexual ? why.
3. mention the number of ovaries in human female? and number of ova released per month?
​

Answer 1

Answer:

2 asexual as it takes less time in reproduction and only one parent is involved

Answer 2

1.The most common mode of asexual reproduction is through the formation of asexual spores, which are produced by one parent only (through mitosis) and are genetically identical to that parent. Spores allow fungi to expand their distribution and colonize new environments.

2.Sexual reproduction is a better mode of reproduction as compared to asexual reproduction because it involves meiosis and the fusion of male and female gametes. Such a fusion involving two parents results in offspring which are not identical to the parents.

3.At birth, there are approximately 1 million eggs; and by the time of puberty, only about 300,000 remain. Of these, only 300 to 400 will be ovulated during a woman's reproductive lifetime. Fertility can drop as a woman ages due to decreasing number and quality of the remaining eggs.
