Plant Genetics & The Green Revolution

Front 1

genetics

Back 1

Study of the way physical traits are passed from parents to offspring.

Front 2

genes

Back 2

Sequence of DNA base pairs that codes for one hereditary trait; found on a chromosome.

Front 3

allele

Back 3

An alternative form of a gene that occupies the same place on a specific chromosome to help determine a specific trait.

Front 4

dominant allele

Back 4

An allelle that determines the phenotype whenever present in a gene.

Front 5

recessive allele

Back 5

An allele that determines the phenotype only when paired with an identical one to for homozygous recessive.

Front 6

genotype

Back 6

Genes possessed by an individual organism, including dominant and recessive alleles.

Front 7

homozygous

Back 7

Having 2 dominant or 2 recessive alleles of a given gene.

Front 8

heterozygous

Back 8

Having one dominant allele and one recessive allele of a given gene.

Front 9

sd1

Back 9

Symbol to represent the semi-dwarf rice plant that is recessive.

Front 10

SD1

Back 10

Symbol to represent the rice plant that is tall.

Front 11

Tt

Back 11

Symbol that represents the heterozygous rice plant....tall.

Front 12

phenotype

Back 12

Charateristics which appear in an individual as determined by both genotype and environment.

Front 13

hybrid

Back 13

Offspring of a cross between two unlike parents (of the same or different species); trait mixes characteristics of 2 genes.
