Which process would lead to offspring with the exact same genetic information as the parent
A. A plant growing from a seed
B. A bacterium splitting in two
C. A tree growing from the stump of another tree
D.. a bird laying an egg
B. A bacterium splitting in two
B. A bacterium splitting in two
The process that would lead to offspring with the exact same genetic information as the parent is the process of binary fission, which is the method of reproduction used by certain unicellular organisms, such as bacteria.
To get the answer, we need to understand the different methods of reproduction.
Option A, "A plant growing from a seed," involves sexual reproduction in plants. In this process, the seed is formed through the fusion of genetic material from two different parent plants, resulting in offspring with a combination of genetic traits from both parents. Therefore, this option does not lead to offspring with the exact same genetic information as the parent.
Option C, "A tree growing from the stump of another tree," typically involves a type of asexual reproduction called vegetative propagation. While the new tree is genetically identical to the parent tree, the initial tree must regrow from the leftover stump, and there might be slight genetic variations due to mutations or changes during growth.
Option D, "A bird laying an egg," also involves sexual reproduction. Birds lay eggs that are fertilized by male birds, which contribute genetic material to offspring. Therefore, this option does not lead to the exact same genetic information as the parent.
Option B, "A bacterium splitting in two," is the correct answer. Bacteria reproduce through a process called binary fission, where a single bacterium divides into two identical daughter cells. Binary fission results in offspring with the exact same genetic information as the parent bacterium, making it the process that leads to offspring with identical genetic information.
So, the correct answer is B. A bacterium splitting in two.
