How can recessive alleles be passed on even though they are not seen?

Recessive alleles can be passed on, even if they are not a visible feature. Let us say that the mother of a child has brown eyes (B), she also has the recessive gene of blue eyes (b). The father of the child has brown eyes, and also has the recessive gene of blue eyes. Mom: Bb Dad: Bb All possible combinations: BB, Bb, Bb, bb (blue eyes) The child then has a one in four chance of getting the recessive allel of blue eyes (statistically)

In Mendel's experiment why did wrinkled seeds show up in the F2 generation even though they were not present in the F1 generation?
Wrinkled seeds are recessive The F1generation carried recessive alleles.
A gene that may not show up even though it is there is said to be-?
A gene that may not show up even if it has been passed down is a recessive gene.
What is the gene that does not show up even though it is there called?
This gene is called a recessive gene. However, there are time when it can show up.
Using the word genotype in a sentence?
The plant's genotype gave it a tall phenotype even though its alleles were heterozygous. Add an I and can and chagne the "?" to a ".".
How are traits passed along to offspring?
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.Read more: http://wiki.answers.com/How_is_genetic_traits_passed_from_one_generation_to_the_next#ixzz1FsYuLLOUansw2. 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.
In Mendel's experiment why did wrinkled seeds show up in the F2 generation even though they were not present in the F1 generation?
Wrinkled seeds are recessive The F1generation carried recessive alleles.
How did mendel find out whether the recessive allele were still present in the f1 plants?
he breeded the f1 plants with a recessive homozygous plant and if the offspring (f2) showed the recessive allele, then the recessive allele is still present in the f1 plant
In mendal's experiments why did wrinkled seeds show up F2 generation even though they were not presentin the F1generation?
(Apex Learning) The F1 generation carried recessive alleles.

A gene that may not show up even if it has been passed down is a recessive gene.
Are dominant alleles naturally better for an organism?
No, recessive alleles are equally likely to be inherited (if your dealing with only those two types of alleles). BUT, dominant alleles are the ones that show up. That is precisely why they are called dominant. Compared to recessive alleles, dominant ones will overrule the others, making it the one inherited.
True or false even though a gene has multiple alleles a person can carry only two of those alleles?
True
Why are x linked alleles expressed in males even if they are recessive?
X-linked are not recessive nor dominant. X-linked just do not show. On the sex-linked chromosomes the Y chromosome of the X-Y pair dominates the trait whether its recessive or dominant!Actually, all x-linked alleles are expressed because males only have one x-chromosome, so whatever is there, dominant or recessive, is expressed.
A gene that may not show up even though it is there is said to be?
recessive
A gene that may not show up even though it is there is said to be what?
Recessive.
