Why do organism better suited for their environment leave behind more offspring than other organism?

What is a heritable trait becoming common in a population?
If the mutation causes a characteristic that is carried as a dominate trait, then it can spread through a population. Also, if the characteristic that is brought about by the mutation is beneficial, the organism will be better suited to its environment than others. If the organism passes this trait to its offspring, then it is understood that they should survive in a greater ratio than those without the trait and the trait becomes common.
Explain why a mutation in a sperm or egg cell has different consequences than one in a heart cell?
A mutation in a sperm or egg cell means that the mutation while most likely be passed down to the offspring of that organism. If the mutation is in anything but a gamete, it will not be passed down.
Why are only inherited traits not acquired one necessary for the process of natural selection?
Because the offspring of an organism with a desirable inherited trait is more likely to survive than the offspring of an organism with a desirable acquired trait (because the offspring of an organism with a desirable acquired trait will not have its parent's desirable trait).
What was incorrect about Lamarck's hypothesis?
Lamarck proposed the idea of acquired traits being passed on to offspring, known as the inheritance of acquired characteristics. However, this concept has been proven to be incorrect through the science of genetics, which relies on the understanding of DNA and how traits are inherited through genes, rather than through an organism's interactions with the environment.
If a population of an organism shows more than two alleles for a characteristic what is that called?
codominance
How did Lamarck's ideas differ from Darwin's?
Lamarck believed an individual organism acquired traits during its lifetime and passed those traits on to its offspring. He lacked support for his ideas. Darwin documented how inherited traits could be passed on by natural selection, that adaptations that give an organism an advantage is passed on through subsequent generations and becomes more common. He had evidence for his ideas (finches, tortoises…).
What does herdity mean?
Heredity refers to the passing down of traits from parents to offspring through genetic information. These traits can include physical characteristics, such as eye color and height, as well as predispositions to certain diseases or behaviors. Heredity plays a significant role in shaping an individual's appearance and overall health.
It is often easier to determine if an object or organism possesses the characteristic of life rather than the life itself?
yes it is true
Is it true that the inheritance of biological characteristics is determined by genes that are passed from their parents to their offspring?
It's a bit more complicated than that - but yes.
Does sexual reproduction produce more offspring than asexual reproduction?
Asexual reproduction, such as binary fission, is simply a complete copy of anorganism. There is no genetic variation in the daughter organism from the primary organism. However, when sexual reproduction occurs, there are multiple parties contributing, which combines different genotypes.
All copies of the single parent's genes are passed to the offspring?
In sexual reproduction, each parent contributes half of their genetic material to the offspring. This results in a unique combination of genes in the offspring rather than an exact copy of either parent's genes.
