Answer:

The correct answer will be option-true.

Explanation:

The dichotomous keys are the identification tools which helps in the identification as well as the classification of the organism in taxonomy.

The dichotomous keys are based on the contrasting features which are arranged in the increasing order of the specific differentiation. The characteristics of the specimens are arranged from the general to specific which helps in the classifying the specimens from smaller groups.

Thus, option-true is the correct answer.

What three processes lead to variation among offspring that have the same two parents?
beks73 [17]

Explanation:

Genetic variation in offspring during sexual reproduction is caused by

  • crossing over
  • independent assortment
  • randomized fertilization

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.

  • crossing over:  the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.
  • independent assortment in metaphase I of meiosis: chromosomes align independently and genes segregate independently into new combinations ...in humans 2n, n = 23, 8 million combinations of chromosomes possible
  • randomized fertilization: sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

A female rhesus monkey is exposed to testosterone in utero. As a result, the animal displays some defeminized behaviors as an ad
professor190 [17]

Answer:

organizational effect.

Explanation:

Organizational effect is a long-term effect of hormonal action typically occurring in fetal development or the early postnatal period that leads to permanent changes in behavior and neural functioning. For example, the presence of testosterone in young male rats leads to long-term male-typical behavior, and female rats can be masculinized by neonatal exposure to testosterone.

Organizational effects act during development, often during critical period. Such hormones affect the construction or fine-tuning of sex organs or neural circuits underlying behavioral capacities that will be needed in adulthood.

Organizational effects are often under tight genetic control, and not subject to major influence by environment.

Organizational effects are often irreversible.
