When gregor mendel crossed a tall plant with a short plant, the f1 plants inherited

When Mendel crossed a short plant with tall plants What were the f1 results?

Mendel crossed tall pea plants with dwarf ones. The F1 plants were all tall . When these F1 plants were selfed to produce the F2 generation, he got a 3:1 tall to dwarf ratio of offspring.

When Mendel crossed two true breeding pea plants with contrasting traits eg tall versus short why did all the plants from the first f1 generation only show one of the traits?

When Mendel crossed two ” true-breeding ” pea plants with contrasting traits , why did all the plants from the F1 generation only show one of the traits ? All of the F1 generation was heterozygous for the trait . Individuals that have two different forms of a gene are called _____ for that gene.

When Gregor Mendel crossed homozygous tall plants with homozygous short plants all the offspring were tall because?

Each of the offspring has one “T” allele, so they are all tall plants . This is because the “T” allele is dominant over the “t” allele, so a plant with one “t” allele and one “T” allele will only display the traits of the “T” allele, which in this case is a tall pea plant .

When Mendel crossed a true breeding white flowered plant with a true breeding purple flowered plant the f1 generation?

Mendel noted that hybridizing true – breeding (P generation ) plants gave rise to an F1 generation that showed only one trait of a characteristic. For example, a true – breeding purple – flowering plant crossed with a true – breeding white – flowering plant always gave rise to purple – flowered hybrid plants .

Why were all the plants in the f1 generation 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 a true breeding tall plant with a true breeding short plant the f1 offspring were?

gBio: Section 11.1 – The Work of Gregor Mendel

A B
Mendel noticed that each “factor” in pea plants had two “forms.” These “forms” would later be called ___. alleles
When Gregor Mendel crossed true – breeding tall plants with true – breeding short plants , the offspring were ___. all tall

Why does the trait for shortness seem to skip a generation?

Recessive traits can skip generations because a dominant phenotype can be produced by either a homozygous dominant genotype or a heterozygous genotype.

How many times do you need to keep self fertilizing the colored plants to get a purebred colored plant?

Choose several of the colored flower plants , self – fertilize them, then plant and grow the seeds. How many times do you need to keep self – fertilizing the colored plants to get a purebred colored plant ? Indefinitely, until you get all colored offspring.

When Mendel crossed true breeding tall pea plants with true breeding short pea plants What was the result?

Representation of results from one of Mendel’s experiments. 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.

When a tall plant is crossed with a short plant?

Explanation: According to the mechanism of inheritance, when a pure tall plant and short plant crossed together, the resulting offsprings of f1 generation are all tall . Breeding of the offspring from f1 generation results in the growth of both ” tall and short plants “. There was one short plant in four.

What happens when two homozygous plants are crossed?

When true-breeding, or homozygous , individuals that differ for a certain trait are crossed , all of the offspring will be heterozygous for that trait. If the traits are inherited as dominant and recessive, the F1 offspring will all exhibit the same phenotype as the parent homozygous for the dominant trait.

What are Mendel’s factors called today?

Mendel’s ” factors ” are now known to be genes encoded by DNA, and the variations are called alleles. “T” and “t” are alleles of one genetic factor , the one that determines plant size.

Can two plants with white flowers produce offspring with purple flowers?

For example, they may recognize that a plant with white flowers crossed with itself or another plant with white flowers will produce only white flowered plants , while a purple – flowered plant crossed with itself or another purple – flowered plant sometimes produces white – flowered offspring .

Can two plants with purple flowers produce offspring with white flowers quizlet?

Heterozygous contains two different alleles of the same gene. If a purple – flowered plant is crossed with a purple – flowered plant , can they have white flowered offspring ? It depends on the genotype.

What percentage of the offspring from the first generation cross is likely to have purple flowers white flowers?

Predicting Offspring Phenotypes Therefore, in this cross, you would expect three out of four ( 75 percent ) of the offspring to have purple flowers and one out of four (25 percent) to have white flowers. These are the same percentages that Mendel got in his first experiment.
