Genetics Flashcards

Front

an alternative form that a single gene can have for a particular trait

Back

Allele

Front

a chromosome that is NOT a sex chromosome

Back

Autosome

Front

An individual that is heterozygous for a recessive disorder, and therefore expresses the dominant phenotype

Back

Carrier

Front

condensed DNA-containing structure that carries genetic material from one generation to another

Back

Chromosome

Front

Non-mendelian pattern of inheritance that occurs when neither allele is dominant and both alleles are expressed.

Back

Codominance

Front

exchange of chromosomal segments between a pair of homologous chromosomes during prophase I of meiosis

Back

Crossing Over

Front

cross of 2 individuals differing in 2 traits; looking at the resulting offspring's genotype and phenotype

Back

Dihybrid Cross

Front

Having 2 copies of each chromosome; represented as (2n); these are body/somatic cells

Back

Diploid

Front

relationship between alleles in which the phenotype of one allele masks the phenotype of the other allele.

Back

Dominance

Front

Mendel's name for a specific trait that appeared in the F1 generation
