Reproduction: Sexual or Asexual
This type of reproduction requires two parent organisms
Sexual reproduction
A chart to look at the possible allele combinations of offspring from two parent organisms
Punnett square
This is the genetic code and allele combination of an organism.
Genotype
The product of reproduction, a new organism produced by one or two parents
GMO stands for...
Genetically modified organism
This type of reproduction requires only one parent
Asexual reproduction
How many possibilities are generated in a punnett square to predict the genotype of an offspring?
4
The observable characteristic based on an organisms genotype
Phenotype
A highly structured and organized piece made up of DNA, located in the nucleus
Chromosome
What is one advantage and one disadvantage of asexual reproduction?
Advantage: Many offspring, very quickly
Disadvantage: Difficulty adapting, shorter lifespans
The offspring are genetically identical to the parent
Asexual reproduction
In guinea pigs, short hair is dominant (H) and long hair is recessive (h). One parent has a genotype of HH and the other parent has a genotype of Hh, what will the phenotype be of the offspring?
Short hair
H = curly hair and h = straight hair. An organism has an allele combination of Hh, what is the phenotype of the organism.
Curly hair
The basic physical and functional unit of heredity that controls a specific trait
Gene
Brown eyes are dominant and blue eyes are recessive. Zac Efron has blue eyes but both of his parents have brown eyes. How is this possible?
Both parents must have heterozygous allele combinations
Siblings may look similar, but not exact copies due to _______ in their genes,
Variation
In an organism that reproduces sexually, the dominant trait is brown eyes (B) and the recessive trait is blue eyes (b). One parent has a genotype of BB and the other parent has a genotype of bb. What is the percent chance that the offspring will have brown eyes?
100%
R = round face and r = long face. The offspring has a genotype of rr. What is the phenotype of the organism?
Long face
The different versions of a gene
Allele
Finish the lyrics: No pigment in my eyes, little b genotype (blue blue blue blue). Mom and dad eye's brown so we don't look alike...
Dang. I'm adopted?
Name four types of asexual reproduction
budding, binary fission, vegetative propagation, regeneration
In rabbits, black fur is dominant to white fur. If a Bb male reproduced with a Bb female, what is the percent chance the offspring will have white fur?
25%
In humans, "baldness" is a dominant trait (B) and "not bald" is a recessive trait (b). Bob is bald. What are the possible genotype combinations for Bob?
BB or Bb
The number of chromosome pairs in the nucleus of every cell.
23 pairs
Name someone who has a homozygous recessive allele combination for hair color.
Anyone with light hair color is named.
