hello user!

1. In the inheritance of plants more than one pair of traits in cross simultaneously, the factors responsible for each pair of traits are distributed independently to the gametes.
2. This can be explained by taking pea plants with two contrasting characters.
3. Colour of peas – yellow and grey symbolically indicated as Yy .
4. Shape of peas – round and wrinkled symbolically indicated as ‘R’ ‘r’.
5. The plants with yellow and round seeds (pure) were crossed with those having green and wrinkled seeds. (pure).
6. All pea seeds that were yellow and round skin. Each pea will have factors ‘Yy Rr’.
7. Since yellow colour (Y factor) and round skin (R factor) are dominant traits. All the pea seeds will be round and yellow (F1 generation).
8. In F2 generation some seeds were round and yellow (Yy Rr or YYRR) some were round and green (yy RR yy Rr), some seeds were wrinkled and yellow (Yy rr or Yy rr) and some seeds were wrinkled and green (yyrr).
