Rohan
Heredity |
The passing of traits from parents to offspring
Relates to K2 and K3 because that's when Mendel discovered heredity
|
|
|
Rohan
Dominant trait |
The trait observed when at least one dominant allele for a characteristic is inherited
Relates to K4 because alleles make up whether it is a dominant trait or not
|
|
|
Rohan
Recessive trait
|
A trait that is apparent only when two recessive alleles for the same characteristic are inherited
Relates to K4 because alleles make up whether it is a recessive trait or not
|
|
|
Rohan
Genes |
Segments of DNA that carry hereditary instructions and are passed from parent to offspring; located on chromosomes
Relates to K4 because alleles make up genes |
|
|
Rohan
Alleles |
Different forms of a single gene
Relates to K4 because genes are made up of alleles |
|
|
Rohan
Genotype |
The inherited combination of alleles
K4 because genotype have to do with genes and alleles |
|
|
Rohan
Phenotype |
An organism's inherited appearance
K4 because phenotype have to do with genes and alleles |
|
|
Rohan
Probability |
The mathematical chance an event will occur
Has to do with K5 because you use punnet squares to find probability
|
|
|
Rohan
Heterozygous |
Having dissimilar pairs of genes for any heredity characteristic
Has to do with K4 because there are genes and alleles in here |
|
|
Rohan
Homozygous |
Having identical pairs of genes for any given pair of hereditary characteristics
Has to do with K4 because there are genes and alleles in here |
|
|
Rohan
Incomplete Dominance |
Incomplete Dominance refers to a genetic situation in which one allele does not completely dominate another allele, and therefore results in a new phenotype.
Relates to K6 because it has to do with a monohybrid cross
|
|
|
Rohan
Codominance |
Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.
Relates to K6 because it has to do with a monohybrid cross
|
|
|
Rohan
Ratio |
A ratio is a statement of how two numbers compare. It is a comparison of the size of one number to the size of another number. All of the lines below are different ways of stating the same ratio.
Has to do with K5 because you use punnet squares to find probability
|
|
|
Rohan
Chromosome |
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
Relates to K4 because genes and alleles are located on the chromosome |
|
|
Rohan
Self-pollination |
Self-pollination is when pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in Gymnosperms). There are two types ofself-pollination: In autogamy, pollen is transferred to the stigma of the same flower.
K4 because it's copying off of alleles/genes
|
|
|
Rohan
Cross-pollination |
The transfer of pollen from the male reproductive organ (an anther or a male cone) of one plant to the female reproductive organ (a stigma or a female cone) of another plant. Insects and wind are agents of cross-pollination.
K4 because it's copying off of alleles/genes
|
|
|
Rohan
Monohybrid |
The hybrid of parents that differ at only one gene locus, for which each parent is homozygous with a different allele.
Has to do with K5 because you're solving problems based on monohybrid crosses
