When Mendel crossed true-breeding tall plants with true-breeding dwarf plants all of the resulting offspring were?

When Mendel crossed true-breeding tall plants with true-breeding dwarf plants all of the resulting offspring were?

When Gregor Mendel crossed true-breeding tall plants with true-breeding short plants, all the offspring were tall because… If a pea plant has a recessive allele for green peas, it will produce… In the P generation, a tall plant is crossed with a short plant.

Did Mendel cross hybrid plants?

Dominant and recessive traits Mendel crossed pure lines of pea plants. Dominant traits, like purple flower colour, appeared in the first-generation hybrids (F1), whereas recessive traits, like white flower colour, were masked.

When Mendel crossed a set of true-breeding?

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.

When Gregor Mendel crossed a true-breeding?

Biology 2nd semester final

Question	Answer
When Gregor Mendel crossed true breeding tall plants with true breeding short plants, all the offsprings were tall because	The allele for tall plants is dominant
According to the principle of segregation when gametes are produced	Allele pairs seperate from each other

When Mendel crossed a true-breeding tall pea plant with a true-breeding short pea plant the offspring were?

Biology 2nd semester final

Question	Answer
Organisms that have two identical alleles for a particular trait are said to be	Homozygous
When Gregor Mendel crossed true breeding tall plants with true breeding short plants, all the offsprings were tall because	The allele for tall plants is dominant

When Mendel crossed tall true-breeding pea plants with short true-breeding pea plants How tall were the offspring?

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).

What was the result of the second generation cross?

The results of Mendel’s second set of experiments led to his second law. This is the law of independent assortment. It states that factors controlling different characteristics. are inherited independently of each other.

What was Mendel’s second cross?

A dihybrid cross is a cross between individuals heterozygous at two different loci. Mendel’s second law is also known as the law of independent assortment. The law of independent assortment states that the alleles of one gene sort into gametes independently of the alleles of another gene.

What is the genotype of a yellow pea plant?

E) The genotype of the plant with yellow round seeds can be YYRR or YyRr and will produce YR, Yr, yR and yr gametes, while the genotype of the plant with green wrinkled seeds will be yyrr and produce yr gametes. In pea plants, yellow seeds (Y) are dominant to green seeds (y) and round seeds (R) are dominant to wrinkled seeds (r).

Which is dominant in Mendel’s peas yellow or green?

In Mendel’s peas, yellow seeds are dominant to green. A pure-breeding yellow plant is crossed with a pure-breeding green plant. All of the offspring are yellow. If one of these yellow offspring is crossed with a green plant, what will be the expected proportion of plants with green seeds in the next generation? 10.

What are the genes that control the texture of peas?

In pea plants, a single gene controls pea texture. Smooth (S) peas are dominant over wrinkled (s) peas. A plant with smooth peas is crossed with a plant with wrinkled peas. Of the progeny, 252 are smooth and 247 are wrinkled. What are the genotypes of the parent plants?

What makes a homozygous recessive pea plant red?

In the homozygous recessive plant, all the pollen grains stain red. If breeding tests are done by self-pollinating the heterozygous F 1 plants, the progeny consists of blue staining kernels (WxWx and Wxwx plants) and red staining kernels (wxwx plants) in the ratio 3:1.
