A true breeding tall plant was crossed with a true breeding short plant If alleles did not segregate during gamete formation?
All offspring would be heterozygous for the gene controlling plant height. This is because if alleles do not segregate, they remain together and are passed on as a unit. The offspring plants would all be tall because the allele for tallness is dominant over the allele for shortness.

What happened in Mendels experiments when a pea plant received two different alleles for the same traits?
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?
Why did traits show up in the f2 generation that were not present in the f1 generation in Mendel27s experiment?
Traits that were masked in the F1 generation reappeared in the F2 generation due to Mendel's law of segregation. During gamete formation, alleles segregate randomly so that each gamete carries only one allele for each trait. When F1 hybrids are crossed, the recessive allele can be passed down and result in the expression of the trait in the F2 generation.
When plants that are true breeding for different traits of a characteristic are crossed the trait observed in the first generation is called the?
dominant
What happened when mendel crossed a true- breeding?
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.
What two types of plants did mendel cross in his first genertion?
Mendel crossed true-breeding pea plants with contrasting traits in his first generation experiments. Specifically, he crossed a true-breeding purple-flowered plant with a true-breeding white-flowered plant.
What genotype is not true-breeding?
A heterozygous genotype (e.g. Aa) is not true-breeding because it carries two different alleles for a trait and can produce offspring with different genotypes when crossed. True-breeding genotypes are homozygous for a particular trait (e.g. AA or aa) and will consistently produce offspring with the same genotype when crossed.
What happened in Mendel's experiments when the pea plant received two different alleles for the same trait?
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?

What is selective breeding in terms of alleles?
Selective breeding is a process where humans choose certain individuals with desired traits to be parents, aiming to pass those traits to offspring. This can lead to changes in allele frequencies in a population over time, as individuals with specific alleles are favored for reproduction. Ultimately, selective breeding can result in the fixation of certain alleles that confer the desired traits.
The first two individuals that are crossed in a breeding experiment are call the?
P generation
What are the first two individuals that are crossed in a breeding experiment?
the P (parental) Generation
Suppose that two true breeding pea plants are crossed?
100
What is the definition of inbreeding?
Inbreeding is the mating of genetically related individuals, such as closely related family members. It can increase the likelihood of genetic disorders and decrease genetic diversity within a population.
Two true-breeding pea plants are crossed one with purple flowers and the other with white. Their offspring are?
If two true-breeding pea plants are crossed their offspring will show the dominant trait. The flowers will be purple or light purple.
The offspring of two true-breeding plants is .?
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.
