Most teachers will designate the dominant gene capital letter. In Mendel's experiment he crossed purebred Tall (T) with purebred short (t). He got all Tall plants as a result. Tall purebreed genotype is TT and the resulting generation was all tall by heterozygous with a genotype of Tt.

How are autosomal traits related to Mendel's observations of heredity?
Gregor Mendel grew hundreds of pea plants. He was curious as to why some of the plants had different traits. Some plants were tall and others were short. Some plants produced green seeds while others produced yellow seeds.Mendel observed that most of the pea plants' traits were similar to its parents. In this observation, Mendel discovered heredity. Heredity is the passing of traits from parents to offspring.Mendel started his experiments with purebred plants, a plant that always produces offspring with the same form of a trait as a parent. Purebred pea plants self-pollinate (pollinate by themselves.) The pistil produces female egg cells. And the stamens produce pollen that contains male sex cells.Next, Mendel cross-pollinated the plants. He took the pollen from a short plant and applied it to a tall plant. He called this generation the parental generation or the P generation. The offspring of this generation was called the first filial generation. The offspring of this first filial generation were all tall. Mendel was curious as to why the tall plant gene over powered the short plant gene. It was because in pea plants tall genes are the dominant allele while short genes are the recessive allele.When the pea plants from the first filial generation were pollinated, three-fourths of the offspring (called the second filial generation) were tall and one-fourth was short. It showed Mendel that recessive alleles can reappear in the next generation of plants.Some Key AbbreviationsT = dominant allelet = recessive alleleTT = (purebred) a plant that inherited two dominant allelesTt = (hybrid) a plant that inherited one dominant allele and one recessive allelett = (purebred) a plant that inherited two recessive alleles
Using the word genotype in a sentence?
The plant's genotype gave it a tall phenotype even though its alleles were heterozygous. Add an I and can and chagne the "?" to a ".".
What is the genotype for a homozygous tall plant?
For example, if the tall plant stand for T, the genotypes are: TT tt
How do dominant and recessive alleles affect an offsprings phenotype?
The traits inherited depends upon the alleles that have been passed on from the father and mother.The traits that are exhibited is called as the phenotype. Dominant allele needs only one copy to be expressed.For example in a pea plant "T" represents the tall dominant allele and "t" the short recessive allele .TT - when there are two dominant alleles the pea plant will express the tall trait. The pea plant is tall.Tt - when there is one dominant and one recessive allele the pea plant will still express the tall trait.In this case the dominant allele masks the recessive allele and the pea plant is still tall.tt - when there are two recessive alleles the pea plant will express the recessive trait and the pea plant is short.For a recessive trait to show up there should be a pair of recessive alleles.
What are the geneotypes of a homozygous and a heterozygous tall pea plant?
The word genotypes is in reference to the alleles an individual receives at fertilization. Lets say that the allele/gene/trait, genotype for the Tall plant is T and dominate and the allele/gene/trait genotype for the short plant is t and recessive. If the genotype is an homozygous allele/gene/trait has two dominate alleles/genes/traits seen as two capital letters ex: dominate tall=TT or if the genotype is homozygous with two recessive alleles/genes/traits it will have two lower case letters ex: short=tt. If the genotype is heterozygous is a Tall plant that means the allele/gene/trait will have one dominate T=Tall and one recessive t=short and it will look like this Tt and with this genotype a Tall plant will be produce "T", even though that plant will still carry an allele/gene/trait for shortness "t". Tips: homozygous [Gk.homo means same and zygous means balance] & heterozygous [Gk.hetero means different and zygous means balance]
What is the combination of alleles in purebred short pea plants?
Two alleles for tall stems.
Is a purebred pea plant small?
If the pea plant has the genetic to be small in the homozygous state, then it will be and conversely so. One of Mendel's experiments was to cross the purebred tall with the purebred small to see which trait was dominant. The allele for tallness is dominant in the pea plant,.
How dominant or recessive alleles for the trait of stem height determine whether a pea plant will be tall or short?
The dominant trait for height in a pea plant is tall (TT or Tt). The only instance in which a pea plant will be short is if it carries both recessive alleles (tt).
What do the letters on the inside of the punnets square stand for?
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.
What do the letters on the inside of the punnet square stands for?
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.
WHAT DO THE LETTERS ON INSIDE OF THE PUNNET SQUARE STAND FOR?
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.
Explain segregation of alleles using pea plants?
if the pea plant has 2 recessive alleles then the plant is gonna come out short.but if it has 1 recessive and one dominant allele then the plant turns out tall, because the dominant allele can be present without the recessive allele.
When a plant has two dominate alleles for tall stems its alleles are written as what?
(T,T) if t is the letter used for that allele capital letters are used for dominant alleles and lowercase is for recessive.
When a plant has two dominant alleles for tall stems it's alleles are written as?
(T,T) if t is the letter used for that allele capital letters are used for dominant alleles and lowercase is for recessive.
During the formation of gametes in a hybrid tall plantthe allele and the short allele stay together?
During the formation of gametes in a hybrid tall plant, the alleles for tall and short height do not stay together. They segregate and assort independently during meiosis, resulting in a random combination of alleles in the gametes. This allows for a variety of possible genetic combinations in the offspring.
When Gregor Mendel crossed purebred short plants with purebred tall plants all of the offspring were?
tall.
How might a geneticist write the alleles to show that tall pea plant has one allele for tall stems and one allele for short stems?
Tt :)
