Independent Assortment is the second law of inheritance Traits are passed from parents to offspring independently of one another. Independent assortment is random and occurs during Metaphase I of meiosis.  There are two possible alignments for the chromosomes.  Since the alignments are random and not assigned, genetic variation occurs.

Independent grouping of qualities happens amid meiosis in eukaryotes. Meiosis could be a sort of cell division that diminishes the number of chromosomes in a parent cell by half to deliver four regenerative cells called gametes. In people, diploid cells contain 46 chromosomes, with 23 chromosomes acquired from the mother and a moment comparative set of 23 chromosomes acquired from the father. Sets of comparable chromosomes are called homologous chromosomes. Amid meiosis, the sets of homologous chromosome are separated in half to make haploid cells, and this partition, or grouping, of homologous chromosomes is arbitrary. This implies that all of the maternal chromosomes will not be isolated into one cell, whereas the all fatherly chromosomes are isolated into another. Instep, after meiosis happens, each haploid cell contains a blend of qualities from the organism's mother and father.

The sequence with the correct word in place would be DNA --> Gene --> Chromosome

<h3>Organization of genetic information</h3>

The basic unit of genetic information is the gene.

Genes are made up of a base sequence of DNA.

Genes are organized into structures known as chromosomes.

Thus, DNA --> Gene ---> Chromosomes

Rotator cuff

The rotator cuff is a group of muscles that perform a variety of tasks such as flexion, abduction, internal rotation and external rotation. The muscles in this group are essential to all movement of the shoulder, making them very essential for upper body mobility. Namely, the muscles of the rotator cuff are supraspinatus, infraspinatus, teres minor and subscapularis.

How is stomach acid neutralized in the small intestine
Bingel [31]
"It converts the inactive enzyme pepsinogen into the active enzyme pepsin, which is responsible for digesting proteins in your stomach. HCL also helps digest other foods in your stomach. Ultimately, HCL is neutralized by chemicals secreted in your small intestine." But, use your own words, though. Because I just hit copy & paste. Hope this helps!

In a species of fish, fin shape is controlled by a single gene that has only two alleles. In a generation of 185 fish, the frequ
scZoUnD [109]

The correct answer is: The recessive allele produces a phenotype that is better able to survive and reproduce than the dominant phenotype.

Natural selection (adaptation mechanism), gene flow, and mutation combine to change allele frequencies across generations. Natural selection tends to increase in frequency beneficial alleles, while it tends to decrease in frequency deleterious alleles.

Mendel determined that for a given character(i.e. pea seed shape) an individual has two factors that these can exist in two form
lions [1.4K]

Answer:

a. different alleles of the seed shape gene.

Explanation:

Mendel crossed different varieties of pea plants and he observed how phenotypic traits passed to the progeny. From these experiments, Mendel formulated the 'First Law of Segregation', where he observed that traits may exist in pairs that segregate (separate) at meiosis. During meiosis, i.e., gamete formation, these two factors separate from each other, thereby each gamete has the same probability of receiving either factor. Nowadays, we know that these two factors represent two different gene variants or 'alleles' for a given gene <em>locus</em>. Alleles can be classified into dominant or recessive as in the example above described, where the R factor (round) dominates on the r factor (wrinkled) to determine the seed shape.
