What will happen if you get dominant genes from both your parents?
You will have the dominant phenotype for that trait.
How do two heterozygous organisms produce on offspring with a recessive phenotype?
There are two forms of Homozygous inheritance: Homozygous Dominant, and Homozygous Recessive. In order for two parents that are Homozygous to produce a Heterozygous offspring, one of them MUST be Homozygous Dominant, and the other MUST be Homozygous Recessive.
How can 2 purple flowers make a white flower?
Two purple flowers can produce a white flower through a genetic phenomenon called incomplete dominance, where the dominant purple allele and recessive white allele both influence the flower's color. When two heterozygous purple flowers (Pp) are crossed, there is a 25% chance of producing a white flower (pp) due to the combination of alleles.
What is it called when neither allele for a trait is dominant?
There are two cases where this can happen: Case 1: Codominance: Both alleles are equally present but are distinct. a good example of this is when you breed a white cow with a red cow. both white and red are dominant. when you look at the offspring, it is roan; it has both white and red hairs mixed in with each other. Case 2: incomplete dominance: Both alleles are equally present but are not distinct. a good example of this is is when you mix a white flower and a red flower and you get a pink flower
How does codominance work and why does it happen?
Incomplete dominance occurs when a homozygous genotype produces an intermediate, or middle phase before the result. This intermediate is the heterozygous' phenotype.
What will happen if you get dominant genes from both your parents?
You will have the dominant phenotype for that trait.
What will happen if an organism has the dominant gene?
Dominant genes express themselves, phenotype depends upon genes .
If purple flower color is dominant over white flower color how can two purple flowered parents produce while flowered offspring?
It can happen when both parents are a heterozygous
How do two heterozygous organisms produce on offspring with a recessive phenotype?
There are two forms of Homozygous inheritance: Homozygous Dominant, and Homozygous Recessive. In order for two parents that are Homozygous to produce a Heterozygous offspring, one of them MUST be Homozygous Dominant, and the other MUST be Homozygous Recessive.
If purple flower color is dominant over white flowers color how can two purple flowered parents produce white flowered offspring?
It can happen when both parents are a heterozygous
If purple flower color is dominant over white flower color how can two purple flowered parents produce white flowering offspring?
It can happen when both parents are a heterozygous
How did Mendel know the the tall pea plants in the first generation had a hidden factor for shortness?
By "test cross" you can know whether it homozygous dominant or heterozygous dominant...in homozygous both alleles code for the dominant trait, in heterozygous one allele is recessive (what you called a "hidden factor"). To perform the test cross, cross a homozygous recessive with the first generation. Lets suppose tall pea tree in the first generation is hetrozygous dominant (Xx) and has alleles X (dominant) and x (recessive). When we cross it with homozygous recessive (xx) X x x :Xx xx x :Xx xx we get half offspring showing dominant trait (Xx) and half showing recessive (xx). If the first generation was homozygous (which is not possible) the result would be X X x: Xx Xx x: Xx Xx all the offspring showing dominant trait and it doesn't really happen when we cross the first generation with homozygous recessive. It means that the genotype of first generation is heterozygous (has a hidden factor or a recessive allele x). Note:You must know what the recessive and dominant allele means...In presence of a dominant allele, recessice character is not expressed but it is present is heterozygous. If both alleles are recessive (homozygous recessive) then the recessive trait is expressed. If both the alleles are dominant (homozygous dominant) obviusly the dominant trait is showed by the individual.

How can two organisms have the same phenotype but different genotype?
One organism is heterozygosis, the other is homozygous.

What will happen to the recessive allele for PP?
there would be a 100% chance of it being heterozygous (Pp)
