1. Non random mating
                                    In genetic equilibrium individuals must mate at random. However, in many species, individuals select mates based on heritable traits, such as size, strength, or coloration, a practice known as sexual selection.

2. Small population size
                                        Genetic drift does not have major effects on large populations but can affect small populations. Thus evolutionary change due to genetic drift happens more easily in small populations.

<span>3. Immigration or Emigration
                                                 Individuals who join a populations may introduce new alleles into the gene pool. Likewise individuals who leave may remove alleles from the gene pool. Any movement of individuals into (immigration) or out of (emigration) a population can disrupt genetic equilibrium, a process know as gene flow.

4. Mutations
                   Individuals who join a populations may introduce new alleles into the gene pool. Likewise individuals who leave may remove alleles from the gene pool. Any movement of individuals into (immigration) or out of (emigration) a population can disrupt genetic equilibrium, a process know as gene flow.

5. Natural Selection
 if different genotypes have different fitness, genetic equilibrium will be disrupted, and evolution will occur.</span>

Specific regions of eukaryotic chromosomes contain sequence elements that are absolutely required for the proper transmission of
grandymaker [24]

Answer:

A. terminators of replication.

Explanation:

For the proper transmission of genetic information from a mother cell to each daughter cell, the cell copies or replicates its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set. And in order to duplicate and segregate correctly, chromosomes must contain three functional elements which are origins for initiation of DNA replication, the telomeres and the centromeres. Terminators of replication is not a required element.

Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome.
Vladimir [108]

Answer:

D) The structural genes will be transcribed continuously.

Explanation:

Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome.  If she moves the operator to the far end of the operon, past the transacetylase (lacA) gene, the structural genes will be transcribed continuously.

A structural gene is a gene that codes for any RNA or protein product other than a regulatory factor (i.e. regulatory protein).

Mrac [35]

The small, almond-shaped organs of the female reproductive system, suspended by ligaments in the upper lateral portion of the pelvic cavity are known as ovaries.

Ovaries are oval-shaped so are also termed almond-shaped organs and are present on the sides of the uterus in females. In females, the processes of pregnancy and ovulation which is also termed menstruation are controlled by the hormones that are made by ovaries. These hormones include estrogen and progesterone. Another major function of the ovary is that it releases the female gametes known as eggs during the menstrual cycle.

The ovaries are attached to two types of ligaments which are the ovarian ligament and suspensory ligament. Ovaries are connected to the womb by the ovarian ligament while the suspensory ligaments of the ovary contain the ovarian vessels and nerves.
