The genetic makeup of an organism
Genotype
Used to calculate the frequencies of different genotypes and phenotypes among offspring
Punnett Square
Both genes for that trait are not the same
Heterozygous
Pairs of genes that carry the same traits and are found at the same locations on pairs of chromosomes
Alleles
Study of the way traits are passed on from parent to offspring
Heredity
An offspring that has many generations of the same trait
Purebred
A trait that is covered up or seems to disappear
Recessive
Basic unit of genetic information, determine the inherited characteristics
Gene
Characteristics of our genes
Traits
Both genes for that trait are the same
homozygous
Male or female sex cells
Gametes
The study of how traits are inherited in offspring
Genetics
Is a trait that is always expressed, or shown
Dominant
The outside appearance of an organism
Phenotype
Two flowers are crossed and their resulting offspring genotypes are 50% RR and 50% Rr. What are the parent genotypes?
RR and Rr
In flowers, red (R) is dominant to yellow (r). If two flowers that are heterozygous are crossed, what would be their potential genotypes of their offspring?
25% RR 50% Rr 25% rr
