SEXUAL REPRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In many fish species, the female digs a small hole in which to lay her eggs. Later, the male visits and fertilizes the eggs.
A
asexual reproduction
B
sexual reproduction
C
both
D
neither
Explanation: 

Detailed explanation-1: -The females reproduce asexually through gynogenesis, making their daughters identical clones of themselves. This type of reproduction also means that they need sperm to trigger the cloning process.

Detailed explanation-2: -Despite odds, fish species that bypasses sexual reproduction is thriving. An international team of scientists has sequenced the genome of the Amazon molly, a fish that reproduces asexually. The researchers expected that the asexual organism would be at a genetic disadvantage, but the Amazon molly is thriving.

Detailed explanation-3: -Sea turtles are an example of an animal that reproduces sexually, a volvox (green algae) is an example of an organism that reproduces asexually, and a brittle star can reproduce in either way. Help your students understand the sexual and asexual reproduction with these classroom resources.

Detailed explanation-4: -Asexual reproduction generates offspring that are genetically identical to a single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring. Sexual and asexual reproduction have advantages and disadvantages-which is why some organisms do both!
