Because they were all homozygous.

What was gregmendel contribution to genetics?
Gregor Mendel cross-breed pea plants to see what the potential offspring where, so his biggest contributions where to that of heredity. He basically proved genes were passed down without even knowing that they existed.
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
When Gregor Mendel crossed true breeding purple flowered plants with true breeding white flowered plants all the offspring were purple because?
PP X ww or Pw X ww Because all Purple flower plants are dominant and express the color purple. This can be seen in a homozygous cross, or a heterozygous cross, ( shown above ) White plants, to breed true, must be in homozygous condition.
What did Gregor Mendel study to develop the rules for genetic traits?
Around 1857, Gregor Mendel began breeding green peas to study inheritance. Although heredity was still unknown at the time, Mendel was curious about the subject. Mendel worked with green peas because they were simple to test, produced large numbers of offspring, and had different variety of traits. Mendel discovered that when he bred two true-breeding peas: one purple and one white (a purple flower's offspring will always turn out purple) produced offspring of purple flowers (why was it only purple and not white?) because the trait for a purple color for peas is more dominant. Then he decides to breed those new purple flowers. Mendel found a 3 to 1 ratio of purple and white flowers. This led to two laws from Mendel: the law of segregation and the law of independent assortment.He studied the effects genetics had on the colors of the flowers of a plant.
What did Gregor Mendel experiment show For his peas experiments?
He discovered that certain genetic traits obeyed statistical laws. He postulated that the frequency of the appearance of those traits was best explained by dominance, recessiveness and co-dominance of genetic material passed from the parent plants.

What does mean for a pea plant to be true breeding?
all offspring in every generation will have the same characteristics of parent plants
Why did Mendel choose the garden pea plant as his experimental organism?
He studied plants and was a gardener.
What did Medel study to learn about genetics?
Mendel studied dominant and recessive traits in pea plants and flowers that had traits that had either or phenotypes. For example, a pea plant could have round or wrinkled offspring. He would then breed the round and wrinkled together and see what happened.
How do you breed your pet rock?
Throw it against a wall, you will end up with offspring. The parent will be smaller though for some reason.....
Can an O positive mother and O positive father parent an O negative child?
Parent? or breed? An O + mother and an O+ father who breed and produce offspring will produce an O+ offspring, not a - offspring. Of course, through adoption, they can parent whatever blood type they like. :} Positive (+) means you possess certain antibodies in your blood. So if both of you have the antibodies of course your child will too. I am not a doctor...but this was my understanding when researching this question when I was pregnant. I am O+ as well.

A form of genetic engineering in which plants or animals are selected to breed and give offspring with desirable characteristics is known as?
Selective Breeding

selective breeding
How did Mendel evaluate his theory of equal segregation?
Mendel evaluated his theory of equal segregation through the analysis of the results of his experiments with pea plants, where he observed the patterns of inheritance of specific traits over generations. By carefully recording and analyzing the phenotypic ratios of offspring from controlled crosses, Mendel was able to confirm that traits segregate equally during gamete formation and follow specific patterns of inheritance as outlined in his laws of segregation and independent assortment.
Do organisms have to be the the same species in order to breed and produce offspring?
No, organisms of different species can breed and produce offspring. Donkeys and horses can breed and produce mules but mules cannot produce offspring.
