Gene-ius Inheritance
This scientist is known as the "Father of Genetics" for his work with pea plants.
Who is Gregor Mendel?
Traits like height and skin color, which are influenced by multiple genes, are known as ?.
What are polygenic traits?
A shaded shape in a pedigree indicates this.
What is an affected individual?
A Himalayan rabbit’s fur color changes based on this environmental factor.
What is temperature?
In incomplete dominance, crossing a red and white flower results in this color offspring.
What is pink?
In Labrador retrievers, one gene controls fur color, but another gene can mask the color entirely, making the dog yellow. This is an example of ?.
What is epistasis?
A person with type AB blood has this type of inheritance pattern, where both alleles are fully expressed.
What is codominance?
Identical twins have the same DNA, yet they can look slightly different due to ? factors.
What are environmental?
A heterozygous organism with one dominant and one recessive allele will show this type of trait in Mendelian inheritance.
What is the dominant trait?
A single gene that affects multiple traits, such as how sickle cell disease impacts red blood cells, circulation, and immunity, is an example of ?.
What is pleiotropy?
In a pedigree chart, a square represents this gender.
What is male?
This term refers to how both genetics and the environment shape traits like intelligence or weight.
What is multifactorial inheritance?
Mendel’s Law of Segregation states that organisms inherit two alleles for each trait but only pass on ? in a gamete.
What is one allele?
A testcross is used to determine the genotype of an organism with a dominant phenotype by crossing it with an organism that has this genotype.
What is homozygous recessive?
This type of chart is used to track inherited traits across generations of a family.
What is a Pedigree?
Poor nutrition during childhood can affect this genetically controlled trait.
What is height?
This combination of alleles—one from each parent—determines an organism’s genetic makeup.
What is genotype?
A person’s risk for heart disease is influenced by multiple genes, but also by diet and exercise. This makes heart disease a ? trait.
What is a polygenic and environmentally influenced trait?
In blood type inheritance, the possible alleles are ?.
What are A, B, and O?
Despite what many people think, dominant alleles are not always more common in a population than recessive alleles. This is because allele frequency depends on these two main factors rather than dominance. (DOUBLE POINTS!!)
What are natural selection and genetic drift?
