100
Male reproductive cell.
What is sperm
100
Type of cell division where one mother cell divides into two identical daughter cells with the same number of chromosomes as the parent.
What is mitosis.
100
This is used to predict the possible traits of offspring.
What is a Punnett Square.
100
To receive genetic information and traits from a parent or parents.
What is heredity. (Inherit is OK.)
100
DNA that is wound up around proteins in the nucleus of a cell is called...
What is a chromosome.
200
Female reproductive cell.
What is an egg.
200
Type of cell division in which there is a reduction, by half, in the number of chromosomes.
What is meiosis.
200
A basic unit of heredity. These determine a specific trait or traits.
What are genes.
200
Feature that has different forms in a population.
What is a trait.
200
The genetic blueprint that determines a life form.
What is DNA.
300
Any reproductive cell with half of chromosomes, egg or sperm.
What is a gamete.
300
When DNA is copied before cell division but there is a mistake and the DNA changes. Not always bad.
What is a mutation.
300
Most genes have two or more versions which are called....
What are alleles.
300
The two genes an individual has for a trait.
What is the genotype.
300
Both genes carried are the same.
What is homozygous.
400
Biological process by which plants and animals create offspring by combining their genetic material.
What is sexual reproduction.
400
Whip-like projection used in locomotion by sperm. Many one-celled organisms have these.
What is a flagellum.
400
You only need one of these alleles to see this trait.
What is a dominant trait.
400
The trait that you see.
What is the phenotype.
400
The alleles carried are not the same.
What is heterozygous.
500
When sperm and egg cells combine, they form a single new cell called a
What is a zygote.
500
Cells divide until they reach a developmental stage where they change to a more specialized form.
What is differentiate.
500
When neither gene dominates. You see both alleles or a blending of them.
What is a co-dominant trait.
500
A group of organisms or cells produced asexually from one ancestor or stock, to which they are genetically identical.
What is a clone.
500
The presence of natural differences in traits within a species.
What is genetic variation.
