In an experiment with pea plants, two purple flowered pea plants that are heterozygous for the alleles for flower color are crossed?
They are fine; expected ratios might not be seen simply due to chance.

What does codominonce mean in geneticists?
Codominance is a condition where heterozyous alleles at the same site produce and intermediate result. Ex. Red flowered plant crossed with White flowered plant yields 100% Pink flowered offspring. Ex. White Shorthorn cow crossed with Red Shorthorn yields 100% roan offspring.
A homozygous violet flowered pea plant is crossed with a homozygous with flowered pea plant. If the violet color is dominant (V), what is the genotype and phenotype of the F1 generation?

What happened when Mendel crossed a purple flowered pea plant with a white flowered plant?
Mendel observed that all the offspring had purple flowers, showing that purple is dominant over white in pea plants. He discovered the principle of dominance and the concept of alleles.
N an experiment with pea plants two purple flowered pea plants that are heterozygous for the alleles for flower color are crossed The results are offspring with purple flowers 25 offspring with wh?
The results suggest that the allele for purple flowers is dominant (P) and the allele for white flowers is recessive (p). The Punnett square for the cross would show a 3:1 ratio of purple to white flowered offspring, as predicted by Mendel's laws of inheritance. This indicates that the purple flower trait is dominant and the white flower trait is recessive.
Why were all the offsprins purple when gregor menel crossed true breeding purple flowered plants with true breeding white flowered plants?
All the offspring were purple because Mendel was dealing with simple genetic dominance. The purple true breeding parent was homozygous dominant and the true breeding white parent was homozygous recessive. When those two are crossed they create only heterozygous offspring (look up a punnett) and since this is simple dominance those heterozygous will show the phenotype of the dominant allele which is purple.
Typical ratio of traits in mendel first experiment?
In Mendel's first experiment with pea plants, he observed a typical ratio of 3:1 for dominant to recessive traits. This ratio occurs when a heterozygous individual (Aa) is crossed with another heterozygous individual (Aa), resulting in a 25% chance of the offspring inheriting the recessive trait.
What genotype is not true-breeding?
A heterozygous genotype (e.g. Aa) is not true-breeding because it carries two different alleles for a trait and can produce offspring with different genotypes when crossed. True-breeding genotypes are homozygous for a particular trait (e.g. AA or aa) and will consistently produce offspring with the same genotype when crossed.
What is the difference between homozygous yellow peas and heterozygous yellow peas?
Homozygous yellow peas have two identical alleles for yellow color (YY), while heterozygous yellow peas have one yellow allele and one non-yellow allele (Yy). This means that homozygous yellow peas will always produce yellow offspring when crossed, while heterozygous yellow peas have a 50% chance of producing non-yellow offspring when crossed with another heterozygous pea plant.
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.
When two cultives are crossed their offspring will be?
Their offspring will be heterozygous recessive.
In fruit gray body color is dominant over black body color suppose that a gray fruit fly heterozygous for the alleles for body color is crossed with one that has a black body what percentage of the?
In this case, when a gray fruit fly heterozygous for the alleles for body color is crossed with one that has a black body, all offspring will have a 50% chance of inheriting the gray body color and a 50% chance of inheriting the black body color. This is due to the fact that the gray body color allele is dominant and the black body color allele is recessive.
