In his classic pea plant experiments, Gregor Mendel observed that among the offspring of a cross between round and wrinkled seeds, he counted about 5474 round seeds and 1850 wrinkled seeds in the F2 generation. This ratio approximates a 3:1 ratio, supporting his hypothesis of inheritance and the dominance of the round seed trait over the wrinkled seed trait.

How did gregor mendel make sure that the plants with round seeds did not self pollinate?
He allowed plants whose seeds were round or wrinkled in shape to self pollinate. This trait has two variations-either round or wrinkled seeds.

When mendel crossed true breeding pea plants that had round yellow seeds with true breeding pea plants that had wrinkled green seeds some of the offspring had round yellow seeds because round and yell?
When Mendel crossed true-breeding pea plants with round yellow seeds (dominant traits) and those with wrinkled green seeds (recessive traits), the offspring displayed round yellow seeds because the alleles for round shape and yellow color are dominant over the alleles for wrinkled shape and green color. This resulted in a phenotype where the dominant traits mask the effects of the recessive ones in the F1 generation. Thus, all the hybrid offspring exhibited the dominant traits of round yellow seeds.
Two forms of the traits of seed shape in pea plants are?
Mendel described two seed shapes among the pea seeds in his study: Smooth and Wrinkled.
What are the two forms of the trait of seed shape?
Seeds come in different sizes and shapes. Some are oval with a point at one end. This would be an example of an apple seed. Other seeds are helicopters which means they spin when dropped. An example of this seed is a conifer tree seed.

What is the physical trait of round and wrinkled?
Round and wrinkled seeds were observed by Mendel in Pea plant while experimenting on its hybridization process. Round or wrinkled stage of seed is a physical trait in pea plant.

When Mendel allowed heterozygous F1 plants that had round yellow seed to self-pollinate he found that some of the F2 plants had wrinkled green seeds is this true or false?
False. When Mendel allowed heterozygous F1 plants with round yellow seeds to self-pollinate, he found that the F2 generation followed the expected 9:3:3:1 phenotypic ratio. This means that all possible combinations of seed shape (round or wrinkled) and seed color (yellow or green) were observed in the F2 generation in the ratio of 9 round yellow: 3 round green: 3 wrinkled yellow: 1 wrinkled green.
Round seeds are dominate to wrinkled seeds What percentage of the offspring will be round?
If round seeds are dominant and wrinkled seeds are recessive, then in a cross between two plants with heterozygous genotypes (Rr), 75% of the offspring will have round seeds (25% RR, 50% Rr) and 25% will have wrinkled seeds (rr).
What is the probability that a cross between a hybrid pea plant with round seeds and one with wrinkled seeds will produce offspring with wrinkled seeds?
The probability that an offspring will have wrinkled seeds is 2 in 4 or 50%
In pea plants are round or wrinkled seeds dominant?
In pea plants round seeds are dominant to wrinkled. So to have round seeds you either will have two dominant alleles (homozygous dominant) or one dominant and one recessive allele (heterozygous)
Two forms of the traits of seed shape in pea plants are?
Mendel described two seed shapes among the pea seeds in his study: Smooth and Wrinkled.
What was the dominant alleles in Mendel's pea plants?
The dominant alleles in Mendel's pea plants were those responsible for the traits of round seeds (R) versus wrinkled seeds (r), yellow seeds (Y) versus green seeds (y), purple flowers (P) versus white flowers (p), and inflated pods (I) versus constricted pods (i).
