Vocabulary
An individual's observable traits, such as height, eye color, or petal shape.
Phenotype
This type of line is used to connect two individuals who have bred or mated
Horizontal
This part of the cell is where genetic information and chromosomes are stored.
Nucleus
This powdery substance contains the male reproductive cells of a flowering plant
pollen
What is an example of a homozygous genotype - use the letter a
AA or aa
The genetic makeup of an organism, represented by a combination of alleles like BB or Bb.
Genotype
Ranchers use these detailed family lineages to predict crosses that will produce the best combination of desirable characteristics
Pedigree
This environmental factor is a major reason why some individuals might grow larger muscles or different body types than their parents.
Diet or exercise
These female reproductive structures are located inside the ovary and become seeds once they are fertilized by pollen
ovules
: If a homozygous red snapdragon (RR) is crossed with a homozygous white snapdragon (rr), this is the resulting phenotype of the offspring.
Rr
genotype consisting of two different alleles for a specific gene
Heterozygous
If RR is mated with Rr what is the probability of the offspring being rr
0%
This type of reproduction requires only one parent and results in offspring that are genetically identical clones.
Asexual
This part of the flower is responsible for receiving pollen during the process of reproduction.
stigma
If two tan horses (Bb) are mated, this is the percentage of their offspring predicted to have white fur (bb).
25%
Different versions of a gene that can cause different forms of proteins, leading to variations in a trait.
Alleles
Tulip breeders often avoid relying on this method of reproduction because it leads to a mixture of different flower variations rather than identical clones.
sexual reproduction
The process where a sperm and egg combine and their nuclei fuse to form a new cell.
fertilization
Single-celled bacteria reproduce by splitting into two identical halves through this process
binary fission
horses, if you cross a brown horse (BB) with a white horse (bb), this is the percentage of offspring that will be tan (Bb).
100%
An individual’s complete set of chromosomes, often used to check for genetic disorders.
Karyotype
When predicting outcomes, the letters placed on the outside of the Punnett square represent these.
parents genotypes
A form of asexual reproduction where a female's egg cell develops into a clone of herself without the need for sperm or fertilization.
parthenogenesis
In this method, used by planaria and coral, an organism breaks into pieces and each piece regrows into a new individual
fragmentation
to produce the maximum number of tan horses (Bb) in the shortest time, a breeder should cross a horse with this color fur with a horse with white fur.
Brown fur
