Answer:
the separation of one trait does not influence the separation of another trait.
Explanation:
Alleles are different versions of the same trait. For example, brown alleles, green alleles, and blue alleles are different versions of the eye color trait.
All sexually-reproducing organisms possess two alleles for each trait. These alleles may or may not be the same (e.g., an organism may have one allele for brown eyes and one allele for blue eyes, or it may have two alleles for green eyes, etc.).
Gametes, or sex cells (egg cells and sperm cells), are formed during meiosis—a two-step process that only occurs in sexually-reproducing organisms. During meiosis, according to the law of segregation, chromatids that carry alleles are separated into different gametes. According to Mendel's law of independent assortment, the separation of the alleles of one trait does not influence the separation of the alleles of another trait.
cells in the vegetal half of the embryo should be unpigmented those in the animal half and there should be heavily pigmented.
Explanation:
The Yolk molecules moving in the vegetal halves of the egg which is the case in most of the animals, slows down the cell division. These lesser division area or the zone demarcates the area to be vegetal pole and due to lesser cell division, it becomes unpigmented or less pigmented Based on the observation time and perspect with assuming no movement.
The pole opposite to the vegetal, is animal pole which with absence or less of yolk, gets more ability to divide and hence become more pigmented or heavily pigmented. This brings polarity to the egg and becomes telolecithal egg.
There are 23 pairs of chromosomes in each cell in a normal adult human.
It must be widespread, limited in geological time, and distinctive.

Answer:
monoallelic gene expression
Explanation:
<em>Monoallelic expression is a type of gene expression where only a copy out of the two copies of a gene is expressed and the other is silent. </em>
A gene is usually represented by two alleles representing alternate forms of the same character. Individuals inherit an allele each from their two parents for every gene within their genomes.
When only one of the alleles is expressed for a particular gene while the other allele remains silent, such phenomenon is referred to as monoallelic gene expression.
