Gregor Mendel
How traits are passed from one generation to the next-and sometimes skip generations-was first explained by Gregor Mendel. By experimenting with pea plant breeding, Mendel developed three principles of inheritance that described the transmission of genetic traits, before anyone knew genes existed.

Answer:
Explanation:
Possible gametes of OOTt are OT and Ot.
Possible gametes of OoTt are OT, Ot, oT, and ot.
The punnet square is shown in the attached figure.
As per the punnet square there are six genotypes and two phenotyes.
The genotypes with ratios are:
OOTT = 2/16
OOTt = 4/16
OOtt = 2/16
Oott = 2/16
OoTT = 2/16
OoTt = 4/16
The two phenotypes "orange with tall stems" and "orange with small stems" will be present in 12:4 i.e. 3:1.
Answer:
B
Explanation:
By combining drip and flood irrigation. Drip irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the root zone and minimize evaporation.
Flood irrigation is a practice in which an entire field is covered with water, while furrow irrigation adds water through furrows adjacent to crop beds. In flood irrigation systems, soils experience highly anoxic periods which promote denitrification processes.
