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.

In a purebred tall pea plant, the combination of alleles for height is homozygous dominant (TT). This means that both copies of the gene for height are the same and produce the tall phenotype.

Mendel crossed a purebred tall plant with a purebred short plant. What was the phenotype of the f1 generation?
The phenotype of the F1 generation was all tall.
What is the genotype for a homozygous tall plant?
The genotype for a homozygous tall plant is TT. This means that both alleles for the height trait are the dominant allele (T), resulting in a tall phenotype.
How do dominant and recessive alleles affect an offsprings phenotype?
Dominant alleles mask the effects of recessive alleles in heterozygous individuals, so only the dominant allele's phenotype is expressed. Recessive alleles are only expressed when an individual is homozygous for that allele. This means that dominant alleles typically determine the phenotype when present, while recessive alleles only show their effects when no dominant allele is present.
What must be true for a cross between a tall plant and a short plant to produce any short plants?
Both the tall plant and short plant must be heterozygous for the height trait, meaning they each carry one dominant and one recessive allele. When they produce offspring, there is a 25% chance of obtaining a short plant by inheriting two recessive alleles for the height trait.
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.
Mendel crossed a purebred tall plant with a purebred short plant. What was the phenotype of the f1 generation?
The phenotype of the F1 generation was all tall.
What does an alleles for a hybrid tall pea represent?
An allele for tall in a hybrid pea plant represents the gene that codes for the trait of tall height. In the case of a hybrid plant, there are two alleles for height, one inherited from each parent. If both alleles are for tall height (TT or Tt), the plant will exhibit the tall trait.
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,.
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.
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).
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.
What is the genotype for a homozygous tall plant?
The genotype for a homozygous tall plant is TT. This means that both alleles for the height trait are the dominant allele (T), resulting in a tall phenotype.
