When Mendel crossed a true-breeding tall plant with a true-breeding short plant what did the offspring look like?
Mendel studied seven traits which appeared in two discrete forms, rather than continuous characters which are often difficult to distinguish. When “true-breeding” tall plants were crossed with “true-breeding” short plants, all of the offspring were tall plants.
When Gregor Mendel crossed true-breeding tall plants with true-breeding short plants the offspring were all tall because?

| Question | Answer |
|---|---|
| When Gregor Mendel crossed true-breeding tall plants with true-breeding short plants, all of the offspring were tall because | the allele for tall plants is dominany |
| The principles of probability can be used to | predict the traits of the offspring produced by genetic crosses |
Why will all of the F1 generation be tall?
The F1 plants are tall because the T allele is expressed and “cover up” the t allele. So the T (tall) allele is called dominant and t (short) allele is called recessive.
When Mendel crossed pure breeding tall and short?
When a tall and short plant are crossed, all of the offspring are tall. If the offspring self-fertilize, they produce tall and short plants in a ratio of 3:1 in the next generation. Mendel’s actual counts were 787 tall:277 short plants in this generation (2.84:1 ratio).
When Mendel crossed tall plants with tall plants the offspring were?
Mendel observed that the offspring of this cross (called the F1 generation) were all tall plants! Next, Mendel let the F1 generation self-pollinate. That means the tall plant offspring were crossed with each other. He found that 75% of their offspring (the F2 generation) were tall, while 25% were short.
When Mendel crossed true-breeding tall and short parental plants?
When Mendel crossed true breeding tall and short parent plants producing first generation what was produced?
When Gregor Mendel crossed a tall plant with a short plant?
When Gregor Mendel crossed a tall plant with a short plant, the F1 plants inherited… When Gregor Mendel crossed true-breeding tall plants with true-breeding short plants, all the offspring were tall because…
What is the significance of T in Mendelian genetics?
This means that 50% of the gametes of an F 1 heterozygous hybrid carry the factor T and 50% the factor t. Mendel crossed such a hybrid plant (Tt) with a plant of the true breeding, dwarf variety (tt). All the gametes of the homozygous dwarf plant carried the recessive factor t.
What did Mendel’s experiments show about inheritance?
Mendel’s first experiments explain how a single gene segregates in inheritance. When Mendel crossed a true breeding tall plant (female parent) with a true breeding plant of the dwarf variety (male parent), he got tall plants like one parent in the first filial generation designated F 1.
How did Mendel prove that round seeds are more round?
First of all Mendel crossed a pea plant that was breeding true for round seeds with a plant that bred true for wrinkled seeds. The F 1 indicated that roundness was dominant over wrinkled texture of seed coat.
