I think you're talking about Mendel's famous pea plant study. It's not the size that matters, but rather the genotype. The parents have to possess a certain pair of chromosomes to create a specific phenotype (short plants).
Here's your answer:
Let's use T to represent the dominant trait of tallness, and t to represent a recessive trait of shortness.
If both parents are short plants, their genotype would have to be tt (dominant could be TT or Tt). So when you crossed their chromosomes for offspring, their genotypes would also be tt. Therefore, the phenotype would be short.
What else can I help you with?
In pea plants the allele for tallness is dominant. What are the possible genotypes of a tall pea plant?
the tall plant must be heterozygous
In the P generation a tall plant was crossed with a short plant No F1 plants were short Short plants reappeared in the F2 generation because?
A cross between members of the F1 generation (Tt x Tt), results in the genotypic ratio of 1TT:2Tt:1tt genotypes in the F2 generation. Because the tall allele is dominant, the phenotypic ratio would be 3 tall:1 short in the F2 generation.
Pure breeding long stem and pure breeding short stem pee plants are crossed According to Mendel's laws of heridity what will the f2 generation be?
Allele for tall stem (dominant)- T Allele for short stem (recessive)- t The F1 generation would all be tall-stemmed plants with the genotype Tt (heterozygous). The F2 generation would consist of: 25% Tall plants with the genotype TT (homozygous dominant) 50% Tall plants with the genotype Tt (heterozygous) 25% Short plants with the genotype tt (homozygous recessive)
Tall is dominate over short The genotype of a short plant is what?
Tall = T short = t Tall plants genotype would either be TT or Tt, and short plants genotype would be tt.
What letters can be used to model Mendel's cross of true-breeding tall plants with true-breeding short plants in a Punnett square?
Generally speaking, the letters used to represent cross breeding in Punnett squares indicate the characteristic being bred for. In this case, T would represent the tall plants, and S would represent the short plants. Cross-bred plants would most likely be represented by TS.
When Mendel crossed short tt pea plants with short pea plants the offspring were?
When Mendel crossed short tt pea plants (homozygous recessive) with short pea plants that were heterozygous for height (Tt), the offspring would display a phenotypic ratio of 1 short (tt) to 1 tall (Tt). This is because the short plants (tt) can only contribute recessive alleles, while the heterozygous plants (Tt) can contribute either a dominant (T) or a recessive (t) allele. Therefore, half of the offspring would be tall and half would be short.
What is the basis for law?
Mendel first described what is called genetics. He used sweet peas and crossed pure bred plants. For example, he crossed short pure bred (recessive) with tall pure bred plants (dominant). If tall is dominant, all plants would be tall. Crossing these hybrid plants would give a ratio of 3 tall to 1 short. This is the basis from which all studies of genes come from.
When Mendel crossed purebred short plants with purebred tall plants all of the offspring were?
I think not as tall is the dominant allele here.T = tallt = shortTT X ttall would beTt======and tall.
When he crossed to pea plants that have different traits of the same characteristic how was Mandel able to select which plants would be crossed to produce offspring?
visual inspection of phenotypic traits.
If you made a Punnett square showing Gregor Mendels cross between true breeding short plsntd the square would show that the offspring had what?
The Punnett square would show that all offspring would be heterozygous for the trait, meaning they would have one allele for tall plants and one allele for short plants. This would result in all offspring being tall plants phenotypically, but carrying the allele for short plants.
What did mendell hypothesize about first generation plants?
Mendel hypothesized that first-generation plants, when crossed, would display a dominant trait in their offspring. He observed that when he crossed purebred plants with contrasting traits, such as tall and short pea plants, the resulting first-generation (F1) plants exhibited only the dominant trait. This led him to propose the concept of dominance in inheritance, suggesting that some traits mask the expression of others in the presence of a dominant allele.
Can a short pea plant ever be produce from crossing two tall pea plants?
No, the short pea trait is recessive and the tall pea plant trait is dominant. This means that if the plant is a hybrid, it has to be a tall pea plant. The dominant traits "mask" the recessive traits. The plant take one trait from their mom and one from their dad. If either the mom or the dad was not a tall, not hybrid pea plant then their kids would have to be tall be cause they would have one dominant, tall trait
In pea plants the allele for tallness is dominant. What are the possible genotypes of a tall pea plant?
the tall plant must be heterozygous

A cross between members of the F1 generation (Tt x Tt), results in the genotypic ratio of 1TT:2Tt:1tt genotypes in the F2 generation. Because the tall allele is dominant, the phenotypic ratio would be 3 tall:1 short in the F2 generation.
When mendel crossed true breeding tall plants with true breeding short plants all the offspring were tall because?
Tallness is a dominant trait and shortness is a recessive trait according to Mendel's principles of inheritance. When true breeding tall plants (homozygous dominant) are crossed with true breeding short plants (homozygous recessive), all offspring inherit one dominant tall allele, resulting in them being tall.
Why was it important to Mendel's work that peas were true-breeding?
because it helped Mendel discover which plants would be crossed to produce offspring.
Suppose two white flowered pea plants are crossed and produce 1000 offspring how many of those offspring would you expect to have white flowers?
If both parent plants are white-flowered, then all of the 1000 offspring would be expected to have white flowers. This is because the white flower trait is a result of a homozygous genotype, and both parents would pass on the white flower allele to their offspring.
