How is a trait determined?
Genetic traits are determined based on the genes an individual inherits from his parents. All an individual's genes determines his genotype, while factors such as dominance and recessiveness determine phenotype.
What are phenotypes and genotype?
Genotype refers to the genetic traits in an organism. It has to do with the genetic coding of an organism. Such coding is inheritable. The genotype is the genetic load that is copied every time a cell divides, and therefore is inheriteddown to the next generation.genotype is something you can't see with your eyes (ex. dominant, recessive, heterozygous)Phenotype refers to observable, physical manifestations of an organism. The phenotype includes physical characteristics, behaviors corresponding to such species, structures, organs, behaviors, relfexes, etc.phenotype are things that can be seen with your eyes. (ex. colors, growth)The genotype is the genetic programming that provides the phenotype.
What is simple recessive heredity?
Simple heredity is the phenotype results from the influence of a single gene.
There or more forms of a gene that code for a single trait are called?
phenotype
What three ways are human traits controlled?
Human traits are controlled by a combination of genetic factors (inherited from parents), environmental factors (such as diet and lifestyle), and epigenetic factors (changes in gene expression without changes in the underlying DNA sequence). These factors interact in complex ways to influence the development and expression of human traits.
What small genetic change such as a single mutation may result in?
genetic drift....
What is a fatty acid in which all carbons in the hydrocarbon tail are connected by single bonds?
phenotype
Mendel postulated that individuals have elements in pairs that determine a single phenotype What are the paired elements?
gene
What is genetic transformation of an organism?
Single-cell organisms are linked to genetic transformation, they acquires new genetic material from the environment
How large can a single cell be and why?
Genetic Cell
How can a genotype change a phenotype?
no not always due to some phenotypes having more than one gene sequence that affects it, eg; the base sequence for a certain enzyme's synthesis could be TTT but by substituting a T with a C to make TTC in mutation could still be a code for the same enzyme...
What do geneticists call alleles that are both expressed in the phenotype when they are together?
Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.
