REPRODUCTION - Coggle Diagram
REPRODUCTION
SEXUAL REPRODUCTION
Advantages
- Genetic variation can lead to evolutionary advancements
- Better at adapting to the environment
- Produces genetic variation in the offspring
- High level of natural disease-resistance offspring
Definition
Involves two parents and the joining of male and female gametes during fertilisation. The offspring inherit a mixture of genes from both parents, so are different to each other and their parents.
Disadvantages
- Requires time and energy to find a mate
-
- High risk-taking as the mate may carry genetic diseases
- Favourable genetics might not passed to the offspring
ASEXUAL REPRODUCTION
-
Advantages
- Only one parent cells is needed
- Population can increase rapidly when the conditions are favourable
- It is more time and energy efficient as you don't need a mate
- It is faster than sexual reproduction
- Good qualities from parents are retained in the offspring without variation.
Disadvantages
- It does not lead to genetic variation in a population
- The species may only be suited to one habitat
- Disease may affect all the individuals in a population
- There might be the risk of food and space competition.
