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
a random change in an organism’s DNA.
mutation
The male gamete within a plant or flower.
pollen
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
Provide an example of any homozygous recessive genotype.
aa, ff, gg, etc.
Chromosomes are made up of _______.
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 options for a gene).
Allele
The two letter code that describes an organisms genes. (AA or Aa)
Genotype
Name at least 2 of the phenotypes that Mendel studied within his peas.
seed color, seed shape, flower color, pod color, stem length, pod shape, flower position.
Where are chromosomes located?
Nucleus
A tool scientists use to predict what offspring may look like...
Punnett Square
Gene that is hidden when the dominant gene is present
Recessive
Father of Genetics, studied peas
Hh and Hh
Two heterozygous parents
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
The term that refers to the pollen of one plant being used to fertilize the ovule of a different plant.
Cross Pollination/Cross Fertilization
If tulips exhibit incomplete dominance for color, and homozygous dominant red tulips are crossed with recessive white tulips. What percent of the offspring would be pink tulips?
100% Pink
