Use a punnett square to predict the offspring in a cross between a dwarf pea plant (homozygous recessive) and a tall pea plant (heterozygous). what is the phenotypic ratio of the offspring?

Tall : dwarf is 1:1

Explanation:

Let "T" represents the allele for a tall pea plant

while "t" represents the allele for a dwarf pea plant

Here "t" is  recessive allele.

Genotype of dwarf pea plant (homozygous recessive) - tt

Genotype of tall pea plant (heterozygous) - Tt

A punnet square showing the cross between tt and Tt is given below-

Tt

tTttt

tTttt

Phenotypic ratio -

Tall : dwarf

Tt: tt

2:2

1:1

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

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.
