Genetic Vocabulary Practice

What to do Open a blank page in Educreations or Notability I will show you a word or letter(s) You WRITE what it means, and add a PICTURE/EXAMPLE if you can.

For Example If I said “Cell” You could write something like “the smallest basic unit of life.” and You could draw a cell

Nucleus

Answer: Organelle (cell part) where DNA is stored Examples:

Chromosome

Answer: A single piece of coiled DNA A tight bundle of DNA Examples:

DNA

Answer: A molecule containing coded instructions for life Examples:

Gene

Answer: A section of DNA containing instructions Examples:

Trait

Answer: Any feature of a living thing determined by its genes Examples:

Allele

Answer: One of a number of different forms of a gene Examples:

Dominant

Answer: Any capital letter An allele that covers up recessive alleles Examples: R T B H

Recessive

Answer: Any lowercase letter An allele that gets covered up dominant alleles Examples: r t b h

Homozygous

Answer: Any genotype with two of the same alleles Examples: rr RR BB bb

Heterozygous

Answer: Any genotype with two different alleles Examples: Bb Tt Hh Rr

Homozygous Dominant

Answer: Genotype with two dominant alleles (homo = same, dominant = big/strong) Examples: BB HH TT RR

Homozygous Recessive

Answer: Genotype with two recessive alleles (homo = same, dominant = little/weak) Examples: bb hh tt rr

Genotype

Answer: The genes (letters) an organism has Examples: BB Bb bb TT Tt tt

Phenotype

Answer: The traits (looks) an organism has Examples: Blue Eyes Brown Eyes Hitchhiker’s Thumb Black Hair Curly Hair Dimples

Artificial Selection (aka Selective Breeding)

Answer: The modification of traits by choosing which organisms reproduce Examples:

Genetic Engineering

Answer: The modification of traits by “messing with” the organism’s DNA. Examples:

Genetic Engineering
