During reproduction, a sperm enters through the membrane of an egg. When that happens, it essentially gives up all function except for delivery of the DNA. The egg contains all of the organelles, which includes the mitochondria. Therefore, only the mother's mitochondria is passed onto the offspring.

What is the genetic material that carries information about an organism that is passed onto offspring?
DNA in genes.
Why wouldn't mutation in a lung cell be passed on to offspring?
Mutations in body (somatic) cells, such as lung cells, do not affect the DNA in egg or sperm cells that are passed on to offspring. Only mutations in the DNA of reproductive cells can be passed on to future generations.
How does a characteristic that contributes to few or no offspring not become more common as a result of evolution by natural selection?
The question answers itself: the characteristic is passed onto few or no offspring, and therefore will not spread throughout the population.
What is a modification of genetic mateirial that will be passed onto future generations?
A modification of genetic material that can be passed on to future generations is called a heritable genetic alteration. This refers to changes in the DNA sequence that are inherited by offspring from their parents. Examples include gene editing techniques like CRISPR-Cas9.
Which is expressed a dominant or recessive allele and which is passed on to the offspring?
A dominant allele is expressed when an individual carries one or two copies of that allele. A recessive allele is only expressed when an individual carries two copies of that allele. Dominant alleles are typically passed on to offspring if at least one parent carries the dominant allele.
Could a mutation in a cell in the liver of a human be passed on?
For a mutation to be passed onto the next generation it must be on sex chromosome. If mutation occurs in somatic cells of our body, it will not be passed on to the offspring(s). Mutation that changes one or few base pairs in the DNA is called point mutation.
Is inheritance of acquired traits part of lamarks theory?
Yes. Lamarck hypothesised that living beings acquired traits in their life times by power of will or use and disuse and passed it onto their offspring.
Why a mutagen can have longer-lasting effects in a sex cell than in a body cell?
In a sex cell, the mutagen is passed along to the next offspring, and therfore caried over for a longer amount of time, and still showing up in generations to come. In a body cell, somatic cell mutations are not passed to the next generation.
Why people born with mixture of both male and female is that a evolution?
Only if the trait is passed onto offspring, and only if this happens frequently enough for it to affect the overall distribution of allele frequencies in the population gene pool.
Characteristic that an organism can pass onto its offspring?
Hair ColorEye Color
Which reproductive strategy do insect pest species use?
They usually begin to reproduce at an early age and have large quantities. They usually won't care for them as much or protect them.
How did Lamarck propose that species change over time?
Lamarck proposed that by selective use or disuse of organs, organisms acquired or lost certain traits during their lifetime. Then passed onto offspring-leading to change in species
