Multiple Choice
In the life cycle of sexual reproducers, what is random fertilization?
A
The fertilization of an egg by multiple sperm, resulting in polyploidy.
B
The fusion of gametes from the same individual, leading to identical offspring.
C
The process by which any sperm can fertilize any egg, increasing genetic diversity.
D
The selection of the fittest sperm to fertilize the egg, ensuring the best genetic traits.
Verified step by step guidance
1
Understand the concept of random fertilization: It refers to the process where any sperm can fertilize any egg, contributing to genetic diversity.
Recognize that random fertilization is a key mechanism in sexual reproduction that enhances genetic variation among offspring.
Consider how random fertilization differs from other fertilization processes, such as selective fertilization, where specific traits might be favored.
Explore the implications of random fertilization in terms of evolutionary biology, as it allows for a wide range of genetic combinations.
Reflect on how random fertilization, along with other processes like crossing over and independent assortment during meiosis, contributes to the genetic uniqueness of each individual.
