1. Sickle-cell anaemia is passed on through a recessive gene.

2. The build-up of recessive genes increases the incidence of genetically determined diseases, such as sickle-cell anaemia in humans.

3. Each blood line has its own characters with recessive gene, i. e. high dead rate, illness, small size and meat quality degrading.

4. Rothenbuhler thought that hygienic behaviour might be controlled by two recessive genes.

5. Polyembryony of mango is initiated from nucellar cells. From genetic Points of view, the polyembryonic characteristic of mango is probably controlled by a single pair of recessive gene.

7. The doctor found that both parents are carriers of the recessive gene.

8. The red Border Collie, like the chestnut horse, is the result of a recessive gene pair.

9. The results indicated that bentazone sensitive lethal gene was controlled by a single recessive gene . The Norin 8 m seedling can be killed by bentazone (above 0.05%), but its FI seedlings are safe.
