Genetics
This scientist is known as the "Father of Modern Genetics" for his experiments with pea plants.
Who is Gregor Mendel?
This egg-shaped structure acts as the "brain" of the cell and stores hereditary material.
What is the nucleus?
Each stage of heredity, such as from grandparents to parents, is known by this term.
What is a generation?
This type of trait is expressed even if only one parent passes the gene to the offspring.
What is a dominant trait?
Eye color and hair texture are examples of these in animals.
What are inherited traits?
Mendel discovered the basic principles of this process, which is the transfer of traits from one generation to the next.
What is heredity?
Deoxyribonucleic acid is the full name for this molecule that carries genetic instructions.
What is DNA?
While an organism's physical appearance is its phenotype, this term refers to its specific combination of alleles.
What is a genotype?
These traits stay hidden unless both parents pass the gene to the offspring.
What is a recessive trait?
Leaf shape and flower color are common inherited traits found in this group of organisms.
What are plants?
In plants, features like seed size, fruit color, and this vertical characteristic are all inherited traits.
What is plant height?
Humans typically have 46 of these thread-like structures, which come in 23 matching pairs.
What are chromosomes?
These are the different forms of a gene, which offspring inherit—one from each parent.
What are alleles?
This term describes an organism that has two identical alleles for a specific trait.
What is homozygous?
In puppies, this specific physical condition is a recessive trait requiring a gene from both parents.
What is deafness?
Humans typically have this total number of thread-like structures in each cell, which come in 23 matching pairs.
What is 46?
This is the specific segment of DNA on a chromosome that codes for one specific trait.
What is a gene?
In the example of the white-faced calf, this parent (the bull) passed on the dominant gene that masked the mother's face color.
Who is the father?
An organism with two different alleles (like "Bb" for red eyes in a fly) is known by this term.
What is heterozygous?
This term refers to the physical appearance of a trait, like a plant being tall or short.
What is a phenotype?
This basic unit of life contains the body's hereditary material and houses the nucleus.
What is the cell?
This molecule, abbreviated as DNA, carries the specific instructions that make every living creature unique.
What is deoxyribonucleic acid?
Parents are considered the second generation and are the "offspring" of this group.
Who are the grandparents?
This type of trait will show its specific feature even if only one parent passes the gene to the offspring.
What is a dominant trait?
If a fruit fly has the genotype $bb$, this specific physical appearance, such as having white eyes or blue eyes in humans, is known by this term.
What is a phenotype?
