Genetics 1
Genes code for these -physical characteristics or ...
Traits
This kind of gene always shows itself over a recessive gene.
Dominant Gene
The language you speak is influenced mostly by...
the environment you grow up in
a random change in an organism’s DNA
mutation
Myostatin protein fits into the cell receptor and creates this muscle type.
Typical Muscle
The passing of traits from parent to offspring is called.
Heredity
Organisms that have two of the same genes are called...
Homozygous
Type of reproduction where offspring are identical to the parents
Asexual
An organisms physical appearance, such as having a pointy nose
Phenotype
Sexual reproduction occurs during this.
Chromosomes are made up of _______.
Genes or DNA
Organisms that have two different genes for the same trait are called...
heterozygous
One of two or more forms of a particular gene (the variations for a gene).
Allele
The two letter code that describes an organisms genes. (AA or Aa)
Genotype
actin and myosin
Where are chromosomes located?
Nucleus
A tool scientists use to organize chromosome pairs.
Karyotype
Gene that is hidden when the dominant gene is present
Recessive
Father of Genetics, studied peas
Building blocks of protein
Amino acids
Having Freckles (F) is dominant over not having Freckles (f). If a person who is heterozygous has children with a person who is also homozygous recessive, what is the probability that their children will have Freckles?
50%
Right-handedness (R) is dominant over left-handedness (r). If a person who is heterozygous has children with a person who is also heterozygous, what would be their children’s possible genotypes?
RR, Rr, rr
A structure made of coiled DNA that transfers hereditary information to the next generation (Comes in pairs)
Chromosome
If one parent is Blood Type AB, and the other parent in type O, what are the chances that they have a child that is type O.
