Anurag Chandra Solutions for Chapter: Heredity and Evolution, Exercise 1: EXERCISE

List any two contrasting characters other than roundness of pea plants that Mendel used in his experiments with pea plants.
 

One plant with dominant tall height bearing purple flowers crossed with another plant with recessive dwarf and white flowers.

What type of cross is it? (Monohybrid cross/Dihybrid cross)

In a cross between plants with purple flowers and plants with white flowers, the offspring of F₁ generation had all white flowers. When F₁ generation individuals were self-bred, the F₂ generation gave rise to 100 individuals, 75 of which had white flowers. Make a cross and answer the following:

What are the genotypes of F₂ individuals?

In a cross between plants with purple flowers and plants with white flowers, the offspring of F₁ generation had all white flowers. When F₁ generation individuals were self-bred, the F₂ generation gave rise to 100 individuals, 75 of which had white flowers. Make a cross and answer the following:

What is the ratio of white to purple flowered plants in F₂ generation?

Giving reasons, state whether the following are homologous or analogous organs:
Forelimbs of human and bird.
 

State with reasons whether the following are homologous or analogous organs:
Wings of butterfly and wings of a bat.
