Cross bb x bb. Write the phenotypic ratio. B is brown hair, b is blonde hair.
What is and 0 brown:4 blonde?
This type of reproduction produces two daughter cells that are genetically identical.
What is asexual reproduction/mitosis?
The way we can tell for certain what genotype a person can be without looking at their parents.
What is look analyzing the traits that the children have.
This trait is passed down in a family due to a lack of money to eliminate that trait.
What is an environmental factor.
The two gametes that are produced during Meiosis.
What are sperm and egg cells?
Cross a homozygous dominant and a homozygous recessive. Write the genotypic and phenotypic ratio. A is athletic and a is not athletic.
What is and 4 brown: 0 blonde?
What is Genetic Crossover/Recombination?
This pedigree is dominant or recessive.
What is dominant?
This factor arises in children that are born with a disease randomly from parents that are normal.
The single letter traits that are passed down from parents to children.
What are alleles?
Cross a homozygous dominant and a heterozygous.
A is athletic and a is not athletic.
Write the phenotypic ratios.
What is 4 Athletic :0 non-athletic?
A punnett square represents _________________ reproduction.
What is sexual?
Name what type of trait this is pedigree is tracking. Your options are autosomal recessive, or autosomal dominant.
What is autosomal recessive?
Some traits like blue skin didn't always exist at first. What needed to happen to our alleles (DNA) to cause it in the first place?
What is a mutation?
The law of having ONLY 1 of each allele on a chromosome passed down from each parent to child
What is the law of segregation
Cross two heterozygotes. Write the genotypic and phenotypic ratio. B is brown hair, b is blonde hair.
What is 1:2:1 and 3:1?
Write the differences between Meiosis (sex cells) and Mitosis (normal cells).
2 things per topic.
What is...
Meiosis: making sex cells, (4 cells, 23 chromosomes)
Used in sexual reproduction
Mitosis: making regular cells (2 cells 46 chromosomes)
Used to repair damaged cells in body
What type of pedigree is the following? I would figure out if its dominant or recessive first, then decide autosomal or X-linked.
What is X-linked dominant?
When you look at this pedigree, what could have caused an affected grandchild to appear even though there is no history of affected ancestors?
State how it could happen and what it causes.
What is:
A mutation in the kid's DNA. It causes the alleles to change.
This occurs because of inbreeding. There is a higher chance of mutations if you mate within your immediate family.
