Mar 29, 2019 · Cell Motility: What You Need to Know. Here's a general review of the key points to remember: • Cell motility is the movement of the cell from one place to another. It's a process that uses energy. • Movement is guided by the cell's cytoskeleton and can involve specialized organelles like cilia and flagella.

Traits are determined by an individual's genotype, the summation of the genes in our DNA. A gene is a portion of a chromosome. A chromosome is composed of DNA and contains the genetic material for an organism. Humans have twenty-three pairs of chromosomes. Twenty-two of the pairs are called autosomes. Autosomes are typically very similar in males a...
How are traits passed from one generation to the next? This happens when gametes unite. When an egg is fertilized by a sperm, for each chromosome pair, we receive one chromosomefrom our father and one from our mother. For a particular trait, we receive what is known as an allelefrom our father and one allele from our mother. An allele is a differen...
When alleles are expressed via simple dominant versus recessive traits, the specific alleles inherited determine how the phenotype is expressed. When an individual has two dominant alleles, the phenotype is the dominant trait. Likewise, when an individual has one dominant allele and one recessive allele, the phenotype is still the dominant trait. W...
A longer second toe and attached earlobes are often cited as examples of a "weird trait" that follows the two dominant/recessive alleles forms of one gene inheritance. Again, however, evidence suggests that both attached earlobe and longer second toe inheritance are quite complex.

Dec 20, 2023 · Genetic inheritance is the process by which traits are passed down from one generation to another through the transmission of DNA. DNA can be found within the chromosomes, which are structures found in the nucleus of cells. Genetic inheritance follows certain principles, such as dominant and recessive traits.

Oct 19, 2023 · The genotype that an individual possesses for a trait, in turn, determines the phenotype —the observable characteristics—such as whether that individual actually ends up with straight, wavy, or curly hair. Genetic variation within a species can result from a few different sources.
