the children or young, such as babies or puppies, that are the result of reproduction

• offspring
• parents
• genes
• code

long, twisted strand of a molecule that stores genetic material

• nucleus

• DNA

• cells

the genotype "aa" would result  in a

• recessive trait
• dominant trait

T = tall, and  t = short. 
So a plant with the genotype
"Tt" would be

• medium sized
• tall
• short

H = brown hair, h = red hair, 
So genotype "Hh" results in

• brown hair
• red hair
•  Brownish red hair
• Reddish brown hair

• Alleles
• DNA

the letters that represent the different forms of a gene

• Genetics
• Chomosome
• Alleles
• DNA

two alleles/letters for on trait that are different (Ex; Dd)

• phenotype
• genotype
• homozygous
• heterozygous

two alleles/letters for on trait that are the same (Ex: DD or dd)

• phenotype
• genotype
• homozygous
• heterozygous

Which of the following is a homozygous dominant genotype?

• tt

• gg

• WW

• Xx
