Genetics Basics
This word describes the physical traits you can see, such as eye color.
What is phenotype?
This type of allele always shows up when present.
What is dominant?
This type of reproduction requires only one parent and produces identical offspring.
What is asexual reproduction?
This term means the likelihood that something will happen.
What is probability?
Organisms like bacteria use this simple method to reproduce quickly.
What is binary fission?
This term refers to the genes an organism has—its genetic makeup.
What is phenotype?
This allele only shows when two copies are present.
What is recessive?
This type of reproduction requires two parents and increases genetic variation.
What is sexual reproduction?
In a Punnett square, two heterozygous parents (Tt × Tt) have this probability of producing a dominant phenotype.
What is 75%?
Traits passed from parents to offspring are controlled by these units.
What are genes?
A section of DNA that contains the instructions for a trait.
What is a gene?
Having two identical alleles for a trait—like TT or tt.
What is homozygous?
The asexual process where a parent splits into two equal parts, common in bacteria.
What is binary fission?
A mutation in reproductive cells increases the probability that this will happen in offspring.
What is a new trait may appear?
In sexual reproduction, each parent contributes one of these to make a pair.
What are alleles?
A change in DNA that can create a new trait or cause problems.
What is a mutation?
Having two different alleles for a trait—like Tt.
What is heterozygous?
A form of asexual reproduction where a new organism grows off the side of a parent.
What is budding?
The probability of producing a recessive phenotype from two homozygous parents TT × tt.
What is 0%?
If an organism is heterozygous (Tt), the trait that shows is the one that is ________.
What is dominant?
This word describes the passing of traits from parents to offspring.
What is heredity?
A tool used to predict how alleles from parents will combine in offspring.
What is a Punnett square?
A type of asexual reproduction where a parent breaks into pieces and each piece grows into a new individual.
What is fragmentation?
If both parents are recessive homozygous (tt × tt), this is the probability their child will show the recessive trait.
What is 100%?
Asexual reproduction leads to offspring that are genetically ________ to the parent.
What is identical?
