Reproduction Rules
What type of reproduction produces offspring identical to the parent?
What is asexual reproduction?
Each parent contributes one of these to make a pair.
What is a chromosome?
What type of letter is used to represent a dominant allele?
What is a capital letter?
What is the term for the inherited combination of alleles?
What is Genotype?
What must an organism inherit to show a recessive trait?
What is two recessive alleles?
What type of reproduction involves two parents and produces genetically unique offspring?
What is sexual reproduction?
A specific section of DNA on a chromosome that controls a trait.
What is a gene?
What type of letter is used to represent a recessive allele?
What is a lowercase letter?
What is the term for the observable traits of an organism?
What is Phenotype?
What do we call an organism with two identical alleles for a gene?
What is homozygous?
How many parents are needed for sexual reproduction?
What is Two?
Different versions of a gene found on chromosomes are called what?
What are alleles?
If an organism has one dominant allele and one recessive allele, which trait will show?
What is the dominant trait?
If an organism has the genotype “aa,” what type of allele pair does it have?
What is Homozygous Recessive?
What do we call an organism with two different alleles for a gene?
What is Heterozygous?
Name one type of organism or structure that reproduces asexually.
What is a bacterium, aphids, potatoes, coral, marbled crayfish, or planaria?
How many alleles does each individual have for one gene?
What is two?
When will a recessive trait be visible in an organism’s phenotype?
Only when the organism has two recessive alleles
The capital letter “T” represents tall plants and “t” represents short plants. What would be the phenotype of a plant with genotype “Tt”?
What is Tall?
If an organism has the genotype “Aa,” will the dominant or recessive trait be visible?
What is the Dominant Trait?
Explain why offspring from sexual reproduction are not identical to their parents.
What is because alleles from two parents combine differently, creating genetic variation?
Describe how alleles might appear on a pair of chromosomes labeled maternal (Mother) and paternal (Father).
Maternal has allele “A” and paternal has allele “a” for the same gene location.
A white-flowered plant has the genotype “pp,” and a purple-flowered plant has “Pp.” What percentage of their offspring would be Purple?
What is 50%?
How can two organisms have the same phenotype but different genotypes?
They could both show the dominant trait (e.g., BB and Bb both show brown eyes).
Explain how Punnett squares help predict offspring traits.
They show possible allele combinations from each parent and the probability of each genotype/phenotype.
