Answer:

Offspring in F1 generation had yellow-seeded pea plants.

Explanation:

When Mendel used yellow-seeded and green-seeded pea plants as parents plants he noticed that all of the offspring of the first generation (F1) were yellow-seeded plants. In the next following generation (F2), phenotype ratio was 3:1 (yellow:green).

After this observation Mendel conclude that yellow-seeded plants are dominant over green-seeded plants. Since he used purebred plants, genotypes were:

P: AA x aa

F1: Aa Aa Aa Aa

F2: AA Aa Aa aa

AA and Aa are genotypes for the yellow seeds, while aa is genotype for green seeds.

Vinil7 [7]

Answer: The part of DNA that the teacher was modelling would be the backbone of DNA.

Explanation:

The DNA is made of double helical structure which is twisted. In the structure of DNA two strands are coiled among each other.

The DNA consists of the nitrogenous bases, phosphate groups and deoxy-ribose sugar.

The backbone of DNA is made up of sugar( alternating )and phosphate group.The nitrogenous bases such as adenine, cytosine ,guanine and thymine are joined to the deoxy-ribose sugar.

This backbone part was part that the teacher was making as a model by using two coiled springs.
