---|---|---|---|---|---|
show | hybrid
🗑
|
||||
The study of gene structure and action and the patterns of inheritance of traits from parent to offspring. This is the branch of science that deals with the inheritance of biological characteristics. | show 🗑
|
||||
show | Gregor Mendel
🗑
|
||||
show | blending theory
🗑
|
||||
Offspring that are the result of mating between genetically similar kinds of parents--the opposite of hybrid. | show 🗑
|
||||
show | genes
🗑
|
||||
show | alleles
🗑
|
||||
show | genotype
🗑
|
||||
show | homozygous genotype
🗑
|
||||
A genotype consisting of two different alleles of a gene for a particular trait. | show 🗑
|
||||
The observable or detectable characteristics of an individual organism; the detectable expression of a genotype. | show 🗑
|
||||
show | dominant allele
🗑
|
||||
The general term for an allele that is masked in the phenotype by the presence of another allele. | show 🗑
|
||||
show | principle of segregation
🗑
|
||||
show | principle of independent assortment
🗑
|
||||
show | punnett square
🗑
|
||||
show | homozygous dominant
🗑
|
||||
The term for a genotype in which there is a dominant allele and a recessive one. | show 🗑
|
||||
show | homozygous recessive
🗑
|
||||
show | homozygous recessive
🗑
|
||||
show | homozygous recessive
🗑
|
||||
The genotype of an individual who is a carrier for a recessive allele that is not expressed in his/her phenotype. | show 🗑
|
||||
show | Mendelian genetics
🗑
|
||||
A trait that is determined by the combined effect of more than one gene. Human skin and hair color are examples. The result of this kind of inheritance is the perception of gradation in the expression of such traits. | show 🗑
|
||||
The inheritance pattern in which a trait is expressed in the phenotype of heterozygous individuals a blend or an intermediate expression.Ex:primroses white flowers are homozygous recessive, red ones are homozygous dominant, & pink ones are heterozygous. | show 🗑
|
||||
The inheritance pattern in which two different alleles for a trait are expressed unblended in the phenotype of heterozygous individuals. Type AB human blood is an example. | show 🗑
|
||||
An inheritance pattern in which a gene has more than two alleles. The human ABO blood type system is an example. It is controlled by at least 3 alleles. | show 🗑
|
||||
show | modifying genes
🗑
|
||||
Genes that can either initiate or block the expression of other genes & control the production of a variety of chemicals in plants and animals. These genes work as master switches which cause changes to occur in our bodies as we grow older. | show 🗑
