Unit C Science

An organism that has two different alleles for a trait; an organism that is heterozygous for a particular trait Hybrid
The offspring of many generations that have the same traits. Purebred
The passing of traits from parents to offspring. Heredity
A characteristic that an organism can pass on to its offspring through its genes. Trait
The set of information that controls a trait; a segment of DNA on a chromosone that codes for a specific trait. Offspring
The set of information that controls a trait; a segment of DNA on a chromosone that codes for a specifice trait Gene
An allele whose trait always shows up in the organisms when the allele is present. Dominant Allele
An allele that is masked when a dominate allele is present. Recessive Allele
Having two identical alleles for a trait. Homozyous Allele
Having two different alleles for a trait. Heterozygous Allele
An organism's genetic makeup, or allele combinations. Genotype
An organism's physical appearance, or visible traits. Phenotype
To predict the results of a particular event. Probability
A chart that shows all the possible combinations of alleles that can result from a genetic cross. Punnett Square
The inheritance pattern that occurs when the alleles are neither dominate or recessive. As a result, both alleles are expressed in the offspring. Codominance
The scientific study of heredity. Genetics
The process in which the number of chromosomes is reduced by half to form sex cells. Meiosis
An organism or cell having only one complete set of chromosomes, ordinarily half the amount of diploids Haploid
An organism of cell having the double of a haploid numbers of chromosomes. Diploid
Any change in a gene or a chromosome. Mutatation
genes are carried from parents to their offspring on chromosomes. Chromosome Theory of Inheritance
A chart of "family tree" that tracks which members of a family have a particular trait. Pedigree
A picture of all the chromosomes in a cell arranged in pairs. Karyotype
An abnormal condition that a person inherits through genes or chromosomes. Genetic Disorder
A pair of chromosomes carrying genes that determine whether a person is male of female Sex Chromosomes
A gene that is carried on the X or Y chromosome. Sex-linked Gene
A person who had one recessive allele for a certain trait, but doesn't have the trait. Carrier
A selective breeding method in which two individuals with identical or similar sets of alleles are crossed. Inbreeding
A selective breeding method in which two genetically different individuals are crossed. Hybridization
An organism that is genetically indentical to the organism from which it was produced Clone
The transfer of a gene from the DNA of one organism,in order to produce an organism with desired traits Genetic Engineering
A process that consists of using genetic engineering to correct some genetic disorders in humans. Gene Therapy
Three or more forms of a gene that codes for a single trait. Multiple Alleles
The main goal was to identify the DNA sequence of every gene in the human genome. The Human Genome Project
All the DNA in one cell of an organism. Genome
A process when an egg and sperm join Fertilization
RNA that copies the coded message from DNA in the nucleus and carries the message into the cytoplasm. Messenger RNA
RNA in the cytoplasm that carries an amino acid to the ribosome and adds it to the growing protein chain. Transfer RNA
A pair of chromosomes made up of many genes joined together like beads on a string. Chromosome Pairs
The process of selecting organisms with desired traits to be parents of the next generation Selective Breeding
the crossing of two individuals that have similar characteristics Inbreeding
The crossing of two genetics of individuals Hybridization
