Round seed shape in peas is an example of a trait controlled by a dominant allele beacause?
Round seed shape in peas is an example of a trait controlled by a dominant allele because the presence of even one copy of the dominant allele results in the expression of the round seed shape phenotype. This means that individuals with either two dominant alleles (RR) or one dominant and one recessive allele (Rr) will have round seeds, while individuals with two recessive alleles (rr) will have wrinkled seeds.
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.
If a pea plant that is heterozygous for round yellow peas RrYy is crossed with a pea plant that is homozygous for round peas but heterozygous for yellow peas RRYy how many different phenotypes are?
There would be four possible phenotypes: round yellow peas, round green peas, wrinkled yellow peas, and wrinkled green peas. This is due to the different combinations of alleles for seed shape (R for round, r for wrinkled) and seed color (Y for yellow, y for green) that can result from the cross.
What did Mendel observe in the F2 offspring that showed him that the alleles for seed shape segregate independently of those for seed color?
Mendel observed a 9:3:3:1 phenotypic ratio in the F2 offspring, where the traits for seed shape and seed color were independently assorted from each other. This suggested that the alleles for seed shape (round/wrinkled) were segregating independently of the alleles for seed color (yellow/green).
What are four different traits that Mendel studied in pea plants?
my mom
Is round dominant over wrinkled?
Yes, in Mendelian genetics, the round seed shape trait is typically dominant over the wrinkled seed shape trait.
What are the genes of a wrinkled pea plant seed?
The wrinkled seed is a round cell but has the ressivienie wrinkled seed in it.
What was the phenotype for the seed shape of both parent plants considering that Mendel observed that round seed shape Capital R was dominant to the wrinkled shape lowercase r?
Both parent plants had the round seed shape phenotype, as the round seed shape (Capital R) is dominant over the wrinkled shape (lowercase r) in Mendel's observations. This means that both parent plants must have had at least one dominant allele (Capital R) for round seed shape.
What 2 forms of traits for seed shape did Mendel observe?
Round (smooth) and wrinkled
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.
Round seed shape in peas is an example of a trait controlled by a dominant allele beacause?
Round seed shape in peas is an example of a trait controlled by a dominant allele because the presence of even one copy of the dominant allele results in the expression of the round seed shape phenotype. This means that individuals with either two dominant alleles (RR) or one dominant and one recessive allele (Rr) will have round seeds, while individuals with two recessive alleles (rr) will have wrinkled seeds.
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.
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.
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.
If a pea plant that is heterozygous for round yellow peas RrYy is crossed with a pea plant that is homozygous for round peas but heterozygous for yellow peas RRYy how many different phenotypes are?
There would be four possible phenotypes: round yellow peas, round green peas, wrinkled yellow peas, and wrinkled green peas. This is due to the different combinations of alleles for seed shape (R for round, r for wrinkled) and seed color (Y for yellow, y for green) that can result from the cross.
How many round seeds and wrinkled seeds do mendel count?
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.
What was the genotype of the offspring that did not share the parent's phenotype?
The genotype of the offspring that had the same phenotype as the parents is rr or wrinkled. The phenotype for the seed shape of both parent plants is round.
