Question

Gregor Mendel studied seven traits in garden peas. He was able to identify certain patterns of inheritance. The patterns were predictable because the traits _______________________.

Answer 1

The patterns were predictable because the traits were contrasting and very less in number.

Step-by-step explanation:

Gregor Mendel came up with certain laws of inheritance with his experiments on the pea plant. Mendel investigated traits in the garden pea plant that were manifested with two opposing traits. The below list shows the characters of the pea plant along with the contrasting traits of each character used by Mendal:

1. Steam height - Tall / Dwarf
2. Flower color - Violet/White
3. Flower position - Axial/Terminal
4. Pod shape - Inflated/Constricted
5. Pod color - Green/Yellow
6. Seed shape - Round/Wrinkled
7. Seed color - Yellow/Green

Answer 2

The patterns were predictable beacuse the traits were not only phenotypical but also contrasting. This allowed Mendel to predict inheritance patterns

Step-by-step explanation:

Mendel coined as the father of genetics carried out his experiments to demonstrated inheritance of traits. The phenotype of an organism illustrates the inherited genes from both parents. The characteristics or phenotype of an organism are controlled by alleles occurring in pairs. They occupy the same locus on homologous chromosome. the contasting traits included:

1. Flower color (purple or white)
2. Flower position (axil or terminal)
3. Length (long or short)
4. Shape (round or wrinkled)
5. Color (yellow or green)
6. Pod shape (inflated or constricted)
7. Pod color (yellow or green)
