A- Parental investment is high in females than male

Reason - Eggs are much larger than sperm.

Females are responsible for gestation and lactation.

B - Parental investment is high in males than female - very rare

Male Mormon crickets transfer a protein-containing spermatophore to females during mating. Almost 30% of a male’s body weight is made up by the spermatophore.

C- Parental investment of males is equal to female

Degree of mate choice should be equal between the sexes.

No sexual dimorphism

The Inflorescence

The stem holding this whole reproductive portion of a plant is called a peduncle.

The major axis above the peduncle called rachis bears the flowers or secondary branches. Also, each flower stalk in the inflorescence is referred to as a pedicel.

Types of Inflorescence

Based on the mode of branching of the main axis or peduncle, the main groups of inflorescences are: 

simple (single)

2)  compound, 

3)  mixed, and 

4)  special
