Vocabulary Set #9
Terms in this set (35)
one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
Any chromosome except for the sex chromosomes. Humans have 44 autosomal chromosomes, or autosomes.
An individual who has a recessive, disease-causing allele at a particular locus on one chromosome of a pair and a normal allele at that locus on the other chromosome.
A distinguishing feature or quality.
That one stick of a chromosome that is before S phase
A relationship between two versions of a gene.
The deliberate breeding of two different individuals that results in offspring that carry part of the genetic material of each parent.
a breeding experiment between P generation (parental generation) organisms that differ in two traits.
An allele or a gene that is expressed in an organism's phenotype, masking the effect of the recessive allele or gene when present.
An allele that produces the same phenotype whether its paired allele is identical or different
The first filial generation, which is comprised of offspring(s) resulting from a cross between strains of distinct genotypes.
The specific location or position of a gene, DNA sequence, on a chromosome.
The second filial generation, which is comprised of offspring(s) resulting from a cross of the members of F1 generation.
A locus (or region) of DNA that encodes a functional RNA or protein product, and is the molecular unit of heredity.
Genetic expression that expression of an allele
Pattern of offspring distribution according to genotype (i.e. the genetic constitution determining the phenotype of an organism)
The passing on of physical or mental characteristics genetically from one generation to another.
Having dissimilar pairs of genes for any hereditary characteristic.
Having identical pairs of genes for any given pair of hereditary characteristics.
The result of interbreeding between two animals or plants of different taxa.
A form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele.
The number and appearance of chromosomes in the nucleus of an eukaryotic cell.
Law of independent assortment
Stating that when two or more characteristics are inherited, individual hereditary factors assort independently during gamete production, giving different traits an equal opportunity of occurring together.
Involves determining trait inheritance by working with only one trait at a time
Law of segregation
Stating that during the production of gametes the two copies of each hereditary factor segregate so that offspring acquire one factor from each parent.
The way a thing turns out
The actual physical expression of the alleles
Ex: Brown hair
The ratio of the offspring determined through their phenotype as predicted from a test cross
The first set of parents crossed in which their genotype is the basis for predicting the genotype of their offspring, which in turn, may be crossed
Bred from parents of the same breed or variety.
An allele that produces its characteristic phenotype only when its paired allele is identical
A chromosome involved with determining the sex of an organism, typically one of two kinds.
Located in a sex chromosome.
Determined by a gene located in a sex chromosome.
The two identical copies formed by the replication of a single chromosome, with both copies joined together by a common centromere
A distinguishing quality or characteristic, typically one belonging to a person.
