What did the difference in the F1 and F2 offspring show Mendel?

What did the difference in the F1 and F2 offspring show Mendel?

What did the differences in the F1 and F2 offspring show Mendel? In all of Mendel’s crosses only one form of the trait appeared in the F1 generation. However, in the F2 generation, the “lost” form of the trait is always reappeared in about one fourth of the plants.

Why is a pea plant that is hybrid for stem height tall?

Why is a pea plant that is a hybrid for stem height tall? How is a gene different from an allele? No because short is recessive and if a dominant gene were present it would be tall. A hybrid will always display the dominant trait.

Can a short pea plant ever be heterozygous for the trait of stem height?

Can a short pea plant ever be a hybrid for the trait of stem height? Why or why not? As part of your explanation, write the letters that represent the alleles for stem height of a short pea plant. No, a short plant has two recessive (tt); hybrids have two different alleles for at trait (Tt).

Which allele for stalk height is dominant?

Question: In pea plants, the allele for tall stalks (T) is dominant over the allele for short stalks (t).

What trait or traits did the plants in the F1 generation exhibit?

What type of cross follows the simultaneous inheritance of two different traits?

A cross concerning two traits is known as a dihybrid cross. Smooth seeds (S) are dominant over wrinkled (s) seeds. Yellow seed color (Y) is dominant over green (g). Inheritance of two traits simultaneously, a dihybrid cross.

What are the seven 7 characteristics and traits of garden pea studied by Gregor Mendel?

Mendel used seven pea plant traits in his experiments which include flower color (purple or white), flower position (axil or terminal), stem length (long or short), seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted), and pod color (yellow or green).

Could a plant ever be a hybrid for stem height?

It can not, because short plant has two recessive alleles, and hybrid has one dominant and one recessive, so the hybrid would be tall because of dominant allele.

Will the hybrid plant be tall or short?

A short plant has two recessive alleles (tt); hybrids have two different alleles for a trait (Tt). A hybrid would appear tall because the tall allele is dominant.

Which allele is dominant in the stalk trait?

In pea plants, the allele for tall stalks (T) is dominant over the allele for short stalks (t).

What is the genotype for the tall plant quizlet?

The genetic makeup of an organism is its genotype. The external appearance of an organism as a result of its genotype is its phenotype. For example, the genotype of a pure tall plant is TT. It consists of two dominant alleles for height—T and T.

What are the traits of the F1 plants stem?

What contrasting traits did the pea plants exhibit in Mendel’s cross?

1. a. In Mendel’s cross for stem height, what contrasting traits did the pea plants in the P generation exhibit? Mendel found that the tall plants in the P generation had two alleles for tall stems and the purebred short plants had two alleles for short stems.

Which alleles determine whether a pea plant will be tall or short?

Explain how dominant and recessive alleles for the trait of stem height determine whether a pea plant will be tall or short. The tall stems is dominant over the allel for short stems. Only a plant with two recessive genes will be short

What are the seven traits Mendel identified as being useful?

The seven traits Mendel identified as being useful to his aims and their different manifestations were: Flower color: Purple or white. Flower position: Axial (along the side of the stem) or terminal (at the end of the stem). Stem length: Long or short. Pod shape: Inflated or pinched. Pod color: Green or yellow. Seed shape: Round or wrinkled.

How many pea plants did mitmendel study?

Mendel would end up growing and studying nearly 29,000 pea plants between 1856 and 1863.
