Genetics
What is genetics?
What is heredity?
The passing of genes from one generation to the next
What is asexual reproduction?
Reproduction that happens with only one parent
What is sexual reproduction?
Reproduction that occurs when two parents produce offspring
how many parents are involved in asexual reproduction?
1
Where are genes located?
In the chromosomes
What is an allele?
Different variations of a gene
Offspring of asexual reproduction usually have ______ DNA to the parent plant?
Identical (same)
offspring of sexual reproduction have genetic material that is ______ the genetic make up from each parent
half
If parents have eyes of two different colors, what eye color will the child have?
Depends on what traits the parents have, The dominant eye color if passed on
How are dominant and recessive traits expressed?
If 1 dominant trait is present it will be expressed.
2 recessive traits must be present for the trait to be expressed.
What is a gene?
Section of DNA that controls what trait we will express (hair color, eye color ...)
What is one disadvantage to asexual reproduction?
Genetically identical, hard to get rid of mutations, hard to adapt
What is one disadvantage to sexual reproduction?
Complex -allows for diversity, takes a longer time,
Budding is a type of?
Asexual reproduction
What is the difference between learned traits and genetic traits?
learned traits can be gained over time
Genetic traits are inherited from parents
Define phenotype
Observable trait resulting from combination of traits given from parents
What is one advantage to asexual reproduction?
A lot of offspring in short time, only need one parent, little time to reproduce
what is one advantage to sexual reproduction?
genetically diverse, easy to adapt, gets rid of mutations quick
Wolfs, coyotes, and dogs are all part of the same family. Why do they have different traits (characteristics)?
Different traits were passed down from their parents
Who is known as the father of genetics
Gregor mendel
Genetic information is stored where?
Chromosome (located in nucleus)
When binary fission occurs (cell splitting in two), what is the genetic makeup of the new cell?
identical to the parent organism.
High genetic variation is the result of what type of reproduction?
Sexual
Three different species are a tan color to help them survive in the desert. Why are three animals found in the desert all the same tan color?
Their parents passed down genes for the tan color through heredity
