Genetics Flashcards
What’s the first stage of mitosis?
What’s the second stage of mitosis?
What’s the third stage of mitosis?
What’s the fourth stage of mitosis?
What’s the fifth stage of mitosis?
Name the type of cell division that’s responsible for growth and repair in the body.
State the type of cell division that produces gametes.
A gamete is a Haploid, Explain what this means?
Determine the number of chromosomes in the cells of a tomato plant if there are 12 chromosomes in a gamete.
The term used to describe-
Alternate forms of gene
The term used to describe-
An organism with different alleles for a particular gene.
The term used to describe
Observable characteristics of an individual.
The term used to describe
individual with two copies of the same allele of a gene.
What are the components of a nucleotide?
Explain the complementary base paring arrangement of the four types of nitrogenous bases.
Give the definition of a recessive allele.
An allele whose trait is masked when a dominant allele is present.
Give the definition for a punnett square.
A chart used to show all possible combinations of alleles that can result from a genetic cross.
Give the definition of an allele
one version of a gene for a specific trait.
Give the definition for a Hybrid
Organisms that have two different alleles for a trait. (heterozygous)
Give the definition of Genetics.
The scientific study of heredity.
Give the definition of Genotype.
The organism’s genetic makeup or allele combinations.
Give the definition of a Dominant allele.
An allele whose trait always shows up in the organism when the allele is present, even if there is only one.
Give the definition of a Trait.
A characteristic of an organism that can pass on to its offspring through genes.
Give the definition of a genome.
All the DNA of an organism: all the genes an organism has.
Give the definition for Heredity.
The passing of genes from parents to offspring.
Give the definition of phenotype.
The organism’s physical appearance or visible traits.
Give the definition of a purebred.
Organisms that produce offspring with the same trait over and over: have the same allele for a particular trait. (e.g. HH or hh- homozygous)
Give the definition of Heterozygous.
Having two different alleles for a particular trait. (e.g. Hh- heterozygous)
Give the definition of a gene.
A set of genetic information that controls a specific trait: a segment of DNA on a chromosomes that codes for a specific trait.
Give the definition of Homozygous.
Having two identical alleles for a particular trait. (e.g. HH)
