In pea plants individuals that are pp for the alleles that code for flower color will have purple flowers what is the phenotypes?
In pea plants, individuals that are Pp for the alleles that code for flower color will have purple flowers. What is the phenotype?
What was Gregor Mendels main experiments?
Gregor Mendel conducted experiments on pea plants to study the patterns of inheritance of traits. He crossed peas with different traits, like round vs. wrinkled seeds or yellow vs. green seeds, and carefully analyzed the offspring to understand how traits are passed from one generation to the next. Mendel's work laid the foundation for the field of genetics.
What happens when alleles for a trait are codominance?
Codominant allele means both the alleles are strong (not recessive small case alphabets are for recessive) so it will give both features the alleles physical appearance (Phenotype) Eg Red flower allele R and White flower allele W will produce Pink flower as both Capital letter R and capital letter W denote both as dominant.
How many alleles influence a phenotype in incomplete dominance?
A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white. So, the homozygous red flower will be red, the homozygous white flower will be white, and the heterozygous flower will be pink. So there are three possible phenotypes in incomplete dominance. There are also no dominant or recessives genotypes.
Are alleles made up of DNA?
All alleles contain DNA. They are the genes. An allele is one form of a gene. For example, the gene for flower color in pea plants has two alleles, one for purple flower color, and one for white flower color.
What is a trait controlled by a single gene that has two alleles?
One example of a trait controlled by a single gene with two alleles is flower color in snapdragons. The gene responsible for flower color has two alleles: one for red flowers and one for white flowers.
What alleles for a flower color could the sex cells carry?
Sex cells could carry alleles for flower color such as red, white, pink, or purple. These alleles determine the specific color expression in the offspring flower. Different combinations of these alleles from the parents contribute to the variation in flower colors seen in the offspring.
What alleles for flower color could the sex cells carry?
it carry purple flower pp or Pp
In pea plants individuals that are pp for the alleles that code for flower color will have purple flowers what is the phenotypes?
In pea plants, individuals that are Pp for the alleles that code for flower color will have purple flowers. What is the phenotype?
In pea plants individuals that are Pp for the alleles that code for flower code for flower color will have purple flowers?
A+ purple flowers.
What is the scientific name for the balsam flower which is used in experiments?
Impatiens
What results when neither allele is dominant?
When neither allele is dominant, the trait that results depends on whether there is codominance or incomplete dominance. In codominance, that traits coded for by both alleles are expressed. For example, if R codes for red and r codes for white, a flower with the genotype Rr would be white with red spots/splotches/stripes/etc. (or red with white spots) - so it is showing both traits. In incomplete dominance - a mixture of the two traits is seen. For example, if R codes for red and r codes for white, a flower with the genotype Rr would be pink (a mixture of red a white).
Mendel discovered that certain traits appear to be dominant over others a phenomenon which later came to be known as Mendel's principle of dominance what is one reason for this?
Mendel ran a series of tests and found the reasonings on why many flowers had different outcomes such as its color. So it is called the Principle of Dominance because of his discovery of knowing which plants would grow which colors. For example, a white flower may be dominant over a purple flower so in this case the purple would be recessive. More plants would grow white flowers because the plant actually transfers its genes from past generations through pollination. This is also referring to Mendels use of Punnett Squares which is a way to find out which color flower is dominant over the other.
The outward expression of a gene?
The outward expression of a gene is determined by the alleles. Alleles come and pairs, and the pairings can be heterozygous or homozygous. For homozygous (both alleles are the same) phenotypes, the trait you see is the same as the alleles. For example, if both alleles are for a white flower, the flower will be white. There are different outcomes for heterozygous (one dominant allele, the other recessive) phenotypes. In complete dominance (the most common), the dominant allele is the the trait you see. For example, the flower has an allele for red (dominant) and white (recessive), it will be red because red is dominant to white. In incomplete dominance, the dominant allele is not strong enough to fully cut out the recessive so trait will be a mix of both. In the flower's case, it would be pink because white will be seen through the red. In codominance, both alleles are expressed just on different areas. The flower would have both red and white splotches.
If orange flower color in a plant is controlled by and allele f and red flower color is controlled by and allele f which flower color is dominant?
Red flower color is dominant because it is represented by the allele "F." Orange flower color is recessive and is represented by the allele "f."
