In a monohybrid cross, if the gene for tall (t) plants was incompletely dominant over the gene for short (t) plants, what would be the predicted result of crossing an intermediate (tt) plant with a short (tt) plant? (hint: you may want to complete a punnett square)

25 percent tall, 50 percent intermediate, 25 percent short
75 percent intermediate, 25 percent short
100 percent intermediate
50 percent intermediate, 50 percent short

The correct answer is 50 percent intermediate, 50 percent short .

Gametes formed by intermediate (Tt) parent plants would be T and t.

Recessive parent plant would produce only one type of gamete which is t.

Hence, only two types of offspring would produce after their cross: Intermediate (Tt) and short (tt) and that too in equal proportion i.e. 50% intermediate and 50% short.

The punnet square is shown in the figure attached for reference.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
