(25 cards)

pleiotropy

Front

the ability of one gene to have multiple phenotypic effects, common for most genes

Back

progeny

Front

offspring; children

Back

codominance

Front

situation in which both alleles of a gene contribute to the phenotype of the organism

Back

allele

Front

Different versions of a gene

Back

Mendelian inheritance

Front

inheritance of traits that follow Gregor Mendel's two laws and the principle of dominance; the basic principles associated with the transmission of genetic material, forming the basis of genetics, including the law of segregation and the law of independent assortment

Back

phenotype

Front

an organisms traits -physical characteristic

Back

character

Front

a heritable feature that varies among individuals

Back

recessive allele

Front

An allele that is masked when a dominant allele is present

Back

dominant allele

Front

determines organisms appearance An allele whose trait always shows up in the organism when the allele is present.

Back

homozygous

Front

an organism having a pair of identical alleles for a character, either dominant or recessive

Back

epistasis

Front

a gene at one locus alters the phenotypic expression of a gene at a second locus

Back

complete dominance

Front

The situation in which the phenotypes of the heterozygote and dominant homozygote are indistinguishable.

Back

pedigree

Front

A diagram of a family tree that shows the occurrence of a genetic trait in several generations

Back

polygenic inheritance

Front

occurs when multiple genes determine the phenotype of a trait

Back

F2 Generation

Front

the offspring of the F1 generation; the second generation of offspring, obtained from a cross

Back

true-breeding

Front

organisms that, when reproducing, create offspring of all the same variety; homozygous

Back

law of independent assortment

Front

the law that states that genes separate independently of one another in meiosis

Back

heterozygous

Front

having two different alleles for a particular gene

Back

incomplete dominance

Front

the situation in which the phenotype of heterozygotes is intermediate between the phenotypes of individuals homozygous for either allele

Back

Punnett square

Front

a diagram for predicting the allele composition of offspring from a cross between individuals of known genetic makeup

Back

genotype

Front

An organism's genetic makeup, or allele combinations.

Back

F1 Generation

Front

The first generation of offspring obtained from a genetic cross of two organisms

Back

P generation

Front

The parental generation in a genetic cross.

Back

trait

Front

each variant of a gene (or character); a specific characteristic that varies from one individual to another

Back

testcross

Front

cross between an organism of an unknown genotype and with a recessive homozygote to determine the genotype of the first organism
