What this is called when traits or characteristics are passed from parents to offspring
What is Heredity?
100
Regardless of its genes, this is the outward appearance of an organism
What is its phenotype?
100
The alleles are not identical but different.
What is heterozygous?
100
The offspring inherit a wider variety of genetic information.
What is one advantage of sexual reproduction?
100
There is greater genetic variety in offspring.
What is the primary advantage of sexual reproduction?
200
These are born from a parent?
What is offspring.
200
The are called the male (sperm) and female (eggs).
What is gametes?
200
The combination of genes in an organism are known as this.
What is genotype?
200
How many chromosomes do humans have?
What is 46 chromosome?
200
In sexual reproduction, the source of genetic material in a zygote.
What is an egg cell and a sperm cell, or gametes.
300
This is a type of reproduction where the parent makes an exact copy of the genetic material (DNA) and passes it on to the offspring; also known as cloning.
What is asexual reproduction?
300
A segment of DNA on a chromosome that codes for a specific trait
What is a gene?
300
These are alternative forms of a gene for each variation of a trait of an organism.
What is an allele?
300
The process that a unicellular organism like bacteria goes through when it begins to split into two cells.
What is binary fission?
300
Asexual reproduction requires only this.
What is one parent?
400
This type of characteristic is inherited, and can either be dominant or recessive.
What is homozygous?
400
This material, present in nearly all organisms, has a double helix shape where two chains of molecules are twisted together and holds the genetic material.
What is DNA?
400
The grid system used to predict the possible outcomes that result from the mating process between two individuals using their genotypes. It looks like a tic-tac-toe.
What are Punnett Squares?
400
Hydras reproduce asexually through this process.
What is budding?
400
Starfish reproduce asexually through this process.
What is regeneration?
500
The trait of an organism that is covered by the dominant form of a trait.
What is recessive?
500
This structure is inside the cell nucleus and contains highly compacted DNA.
What is a chromosome?
500
This allele masks the presence of a recessive allele.
What is dominant?
500
In human sexual reproduction, the offspring receive these amount of chromosomes from each parent?
What is 23 chromosomes?
500
This is the form of reproduction where the offspring vary or differ the most from their parent.
