When Mendel crossed pea plants with green pods with those with yellow pods, the offspring all had green pods if the green pod parent was homozygous. If the green pod parent was heterozygous, then half the offspring had green pods and half had yellow pods.
In his first set of experiments, Mendel crossed purebred pea plants with different traits, such as tall and short plants. He observed the inheritance patterns in the offspring of these crosses over several generations. Mendel showed that traits are inherited independently and proposed the laws of segregation and independent assortment.
Mendel observed that all the offspring had purple flowers, showing that purple is dominant over white in pea plants. He discovered the principle of dominance and the concept of alleles.
When Mendel crossed a true-breeding short plant with a true-breeding tall plant, all the offspring were tall. Which term describes the gene for tallness?
Mendel used purebred plants to ensure that the offspring of his experiments would have consistent and predictable traits. By controlling the genetic makeup of the parent plants, he could more easily observe and analyze the patterns of inheritance in their offspring.
The offspring of two true-breeding plants is also true-breeding, meaning they will consistently display the same traits as the parents. This is because true-breeding plants are homozygous for a particular trait, so when they are crossed, their offspring will also be homozygous for that trait.
because it helped Mendel discover which plants would be crossed to produce offspring.
All the offspring were tall plants. This is because the tall trait is dominant over the short trait in Mendel's experiments on pea plants.
because it helped Mendel discover which plants would be crossed to produce offspring.
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.
purple is dominant over white in Mendel's pea plant experiment, meaning that the offspring inherited at least one purple allele from the purple parent. This resulted in all the offspring showing the purple trait.
I think not as tall is the dominant allele here.T = tallt = shortTT X ttall would beTt======and tall.
Pea Plants
In his first set of experiments, Mendel crossed purebred pea plants with different traits, such as tall and short plants. He observed the inheritance patterns in the offspring of these crosses over several generations. Mendel showed that traits are inherited independently and proposed the laws of segregation and independent assortment.
When Mendel crossed true-breeding pea plants with different traits, he observed that the offspring in the first generation (F1) all displayed one of the parental traits. This led him to propose the Law of Dominance, which states that one trait will mask or dominate another in hybrids.
When Mendel crossed purebred tall tea plants with purebred short tea plants, all the offspring in the first generation (F1) exhibited the tall phenotype. This outcome demonstrated the concept of dominance, where the tall trait masked the short trait. When Mendel allowed these F1 plants to self-pollinate, the second generation (F2) revealed a 3:1 ratio of tall to short plants, indicating that the short trait was still present as a recessive trait. This experiment laid the foundation for Mendel's laws of inheritance.
