What did Gregor Mendel study?
He studied dominant and recessive genes. He studied pea plants and the traits that they obtained from previous generations.
What were the traits that Gregor Mendel studied?
Gregor Mendel worked on following 7 triats in pea plant1. Plant height- Tall (dominant) or short (recessive)2. Seed shape- round (dominant) or wrinkled (recessive)3. Pod colour- Green (dominant) or yellow (recessive)4. Pod shape- Inflated (dominant) or constricted between seeds (recessive)5. Flower position- Terminal or axial6. Seed colour- gray or white7. Pea colour- green or yellow# The round or roundish form of the seed with or without shallow depressions. # The yellow coloring of the seed albumen. # The gray, gray-brown, or leather brown color of the seed-coat, in association with violet-red blossoms and reddish spots in the leaf axils. # The simply inflated form of the pod. # The green coloring of the unripe pod in association with the same color of the stems, the leaf-veins and the calyx. # The distribution of the flowers along the stem. # The greater length of stem.Pea Texture, Plant Hight, Flower Color, Flower Position, Pod Color, Pea Color, and Pea Shape
How did Mendel's experiments with pea plants help us understand how traits are inherited?
Mendel's experiments with pea plants showed that traits are inherited through the passing down of specific units of information, now known as genes. By carefully observing the patterns of inheritance in pea plants, Mendel was able to establish the principles of dominant and recessive traits, as well as the concept of genetic segregation and independent assortment. This laid the foundation for our modern understanding of genetics and how traits are passed down from one generation to the next.
What did gregor Mendel do to study different characteristics in his genetics experiment?
He cross-pollinated plants
How did Gregor Mendel's experiments with pea plants contribute to our understanding of inherited traits?
Gregor Mendel's experiments with pea plants helped establish the principles of inheritance, showing that traits are passed down from parents to offspring in predictable patterns. He discovered the concept of dominant and recessive traits, as well as the idea of genetic segregation and independent assortment. Mendel's work laid the foundation for modern genetics and our understanding of how traits are inherited.
If smooth peas are dominant over wrinkled peas?
If smooth peas are dominant over wrinkled peas, it means that when a plant with one smooth pea allele and one wrinkled pea allele reproduces, all of its offspring will have smooth peas. This is because the dominant allele (smooth) masks the expression of the recessive allele (wrinkled) in the offspring's phenotype.
What was mendel interested in and how is his work popular today?
dominant and recessive genes. to research this, he used peas and investigated the genes which determined whether a pea would be wrinkled or smooth. he was actually a mathematician and he spend ages cross breading wrinkley with straight and counting out the two different types of pea. he counted 1000 peas. approximately 250 were wrinkled and 750 were smooth, leading him to the theory that the gene for smooth pease was dominant eg. wrinkled = w smooth = W W + w = smooth W + W = smooth w + W = smooth w + w = wrinkled the 3:1 ratio hope this helps ;)
If you cross a purebred smooth pea with a purebred wrinkled pea what percentage of the first generation will be smooth peas?
All the first-generation offspring will be smooth peas, as the smooth trait is dominant over the wrinkled trait in peas. This is known as a monohybrid cross involving one gene with two alleles.
In Mendel's experiment why did wrinkled seeds show up in the F2 generation even though they were not present in the F1 generation?
Wrinkled seeds are recessive The F1generation carried recessive alleles.
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)
How many genotypes are there for the smooth pod phenotype?
The smooth pod phenotype in pea plants is typically associated with a specific gene controlled by a single locus with two alleles: one for smooth pods (dominant) and one for wrinkled pods (recessive). The possible genotypes for the smooth pod phenotype are homozygous dominant (SS) and heterozygous (Ss). Therefore, there are two genotypes that can express the smooth pod phenotype.
What are the 5 of the 7 traits that can be studied in pea plants?
it is like a process
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 jeans does a pea plant with wrinkled seeds have?
A pea plant with wrinkled seeds must have two recessive alleles for the wrinkled seed trait (rr). This means that both of its parents must have contributed a copy of the recessive allele for the plant to exhibit wrinkled seeds.
What is the genetic nature of wrinkled phenotype of pea seeds?
The wrinkled phenotype of pea seeds is due to a mutation in the gene that encodes for the starch-branching enzyme known as SBEI. This mutation causes a deficiency in the enzyme, resulting in the accumulation of unbranched starch in the seeds, which leads to the wrinkled appearance.
What allele combinations could a plant with green and wrinkled seeds produce in a gamete?
Ressive genes. Smooth seeds are dominant in the pea plants Mendel used in his experiments.
