What did mendel perform when he crossed plants that were heterozygous for two 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?
What was the dominant alleles in Mendel's pea plants?
Gregor Mendel called them factors, or traits.
Describe gregor mendels experiment with pea plants?
Gregor Mendel's pea plant experiment allowed him great control, as pea plants can self-pollinate or cross-pollinate, and he was able to pollinate them at will. He studied the characteristics of each plant he would cross-pollinate, perform the pollination and plant the resulting seeds, then study the characteristics of the resulting plants.
Much of what we know about single gene traits in humans is the result of studying?
Much of what we know about single gene traits in humans comes from studying pea plants.
What conclusions did Gregor Mendel reach based on his observations of pea plants?
Mendal learned that there are two kinds of traits,,dominate and recessive. He also learned that the enheritance of the traits are determined by genes.
If Gregor Mendel didn't use plants that were not true breeding then would he have discovered dominant and recessive traits?
If Gregor Mendel did not use plants that were not true breeding, he would not have discovered heredity because there would not be any evidence that traits passed on to the next generation and that the offspring retained the traits of the parents.
Mendel used pure breeding pea plants because they showed variation in physical traits from generation to generation?
False.
What did Gregor Mendel do study different characteristics in his genetics experiments?
Gregor Mendel took two true-breeding plants with contrasting traits and cross-pollinated them, producing offspring with genes for both characteristics. He used selective breeding.
What did mendel perform when he crossed plants that were heterozygous for two 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?
Mendel obtained plants that were true-breeding for particular traits by what?
Selfing, self fertilization until the offspring showed not deviation from the parental stock.
How did gregor mendel contribute to understanding of inherited traits?
Gregor Mendel took two different colored pea plants: one had traits for white plants and the other had traits for a red plant. When Mendel cross bred the two plants, a plant with traits for a pink plant grew. This is how Mendel contributed to the understanding of inherited traits.
Mendel obtained plants that were true-breeding for particular traits by?
allowed plants to self-pollinate for several generations
How did Gregor Mendel contribute to your understanding of inheritance?
Gregor Mendel took two different colored pea plants: one had traits for white plants and the other had traits for a red plant. When Mendel cross bred the two plants, a plant with traits for a pink plant grew. This is how Mendel contributed to the understanding of inherited traits.
Who discovered the sex link traits while studying fruit flies?
Gregor mendel
What was the dominant alleles in Mendel's pea plants?
Gregor Mendel called them factors, or traits.
Why did Mendel did thousands of experiment on pea plants?
To study genetics, traits, and the behaviors of those traits.
What observations led Mendel to conclude that some traits were recessive?
Mendel selected true breeding tall (TT) and dwarf (tt) pea plants. Then, he crossed these two plants. The seeds formed after fertilization were grown and these plants that were formed represent the first filial or F1 generation. All the F1 plants obtained were tall.Then, Mendel self-pollinated the F1 plants and observed that all plants obtained in the F2 generation were not tall. Instead, one-fourth of the F2 plants were short.From this experiment, Mendel concluded that the F1 tall plants were not true breeding. They were carrying traits of both short height and tall height. They appeared tall only because the tall trait is dominant over the dwarf trait.
