How are traits passed along to offspring?

Answer 1

Every trait we see is controlled by alleles that are either recessive or dominant. These alleles control what a person, plant, or animal will look, sound, and grow like. If there is a dominant trait present it will always show on the generation with that trait. For a recessive trait to show itself in a generation it must be paired with another recessive gene of the same type thus makeing it a homozygous trait. If a trait is heterozygous, or a dominant and recessive gene paired together, it is usually a result of crossing two things that each have either the recessive or dominant alleles for a trait. For example black or dark brown hair is a dominant trait if someone with blond hair, a recessive trait, marries someone with black or dark brown hair their children will, for the purposes of this example, have red hair which is a heterozygous trait. Same thing with green eyes if, somewhere in the near family tree a family member with brown eyes married someone with blue eyes their kids would have green eyes, like me, my mom has brown eyes, my dad has blue eyes and I have green eyes. Hope this answers your question for you.

answ2. Traits are characteristics, and the above explains the passing-on of traits. But the generation of a trait in the first place is not covered. These are the result of genetic modification, possibly as a result of e.g. radioactive modification of a gene, or of a novel defect or change.

The old question "which is first, the chicken or the egg?" demonstrates this quandary.

The answer of course, is the egg, for it is in this development phase that the new trait is able to be formed. Even if the 'modification' occurred in the chicken, nevertheless it is in the egg that it is first demonstrated.

Answer 3

Traits are passed from one generation to the next through DNA. They can also be passed by what the person observes his or her elders doing.

Answer 4

Traits are passed from one generation to the next is by having a offspring get half of its DNA from its mother and the other half from its father! That process keeps on going on and on!

Answer 5

through genes and adaptation

Answer 6

Inheritance of genes.
