Freud assumed that what was male was normal and that females were inferior
SVETLANKA909090 [29]

Answer:

The complete question is

Freud assumed that what was male was "normal" and that females were "inferior, castrated males."

Our answer is

True

Explanation:

Freud proposes that the boy and the girl begin, pre-Oedipally, having equal emotional position, attracted to the mother, and that the little girl is also a little man as the little girls are not distinct or sexually differentiated.

Freud stands on the concept of a single, masculine, libido: as its initial object is the mother and it's linked to masculinity and activity. He believes that there is no sexual classification or separation at the libido's most primordial phase. He further stated that a genital organization occurs after the Oedipal Complex which was derived in relation to castration as it is the final stage in sexual development. Thus, Freud stands on both children at infancy being ‘little men,’ with their desire construed via the process of a singular masculine libido.

Freud is of the belief that women are the inferior ‘castrated,’ males (lacking of a penis) and men are the normal one (who have penis).

suppose that individuals in a population of beetles differ in the extent of a dark pigment in their coloration. dark-colored bee
sesenic [268]

The coloration of the beetles most likely remains constant, despite differential predation, when it is strictly due to ENVIRONMENTAL factors. Phenotypic traits can be influenced by genes or the environment.

The expression of a given characteristic (i.e., a phenotypic trait) in an individual may be associated with genetic and environmental factors, as well as with the interaction between genetic and environmental factors.

Different types of environmental inputs (e.g., diet, temperature range, oxygen, humidity, light, etc) can influence a given phenotype.

A heritability value near zero (0) indicates that almost all of the phenotypic variability for a given trait is caused by environmental factors.
