Heterozygous dominant.
D = dominant
d = recessive
Same as out breeding for cross with other heterozygous dominant.

What will happen if you get dominant genes from both your parents?
You will have the dominant phenotype for that trait.
How can 2 purple flowers make a white flower?
The purple flowered parents would have to be heterozygous or not full-breeds. For example the purple flowers phenotype would be Pp and Pp instead of PP and PP, which would only produce purple flowers.
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 to the recessive allele for PP?
there would be a 100% chance of it being heterozygous (Pp)
What happen when a population is in a Hardy equilibrium?
Allele frequency is stable The phenotype frequency does not change.
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 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.

When did Dominant Species - video game - happen?
Dominant Species - video game - happened in 1998.
When two homozygotes for same allele are crossed what happens?
If you are looking to see what happens to a specific trait, this is not actually an answerable question in this context. It is so open-ended. Also, parents are not directly homozygous or heterozygous, the genes are. However, in the simplest case, half of the offspring would be homozygous for the gene in question and half would be heterozygous. How this affects the phenotypic trait under observation depends on a lot of other things.
