Term
Mendel's 1st law
The Law of Segregation |
|
Definition
| the two forms of a gene (alleles) present in each parent, segregate independantly. |
|
|
Term
| what type of cross occurs between two true breeding individuals differing in only one character? |
|
Definition
a monohybrid cross
eg/ breeding a green and yellow pea pod of the parent generation |
|
|
Term
| what is the true breeding parents known as? |
|
Definition
|
|
Term
| what is the first offspring of the parent generation known as? |

Term
| what is the difference between genotype and phenotype? |
|
Definition
the genotype is the genetic constitution of an organism
the phenotype is the appearance or other observable characteristics of an organism |
|
|
Term
| what is a homozygous cell? |
|
Definition
| a cell carrying 2 identical alleles at a genetic locus |
|
|
Term
| what is a heterozygous cell? |
|
Definition
| a cell carrying two different alleles at a genetic locus |
|
|
Term
| what method is used to determine the genotype of an individual with the dominant phenotype of a trait |
|
Definition
the testcross
eg. a green podded plant could either be a heterozygote Gg or a dominant homozygote GG |
|
|
Term
| Mendel's Law of Independant Assortment |
|
Definition
| each pair of alleles assorts independantly of each other pair of alleles during gamete formation |
|
|
Term
| what cross involves parents differing in 2 characteristics? |
|
Definition
|
|
Term
which law is this?
the 2 alleles present in each diploid parent segregate independantly - so only one is passed to each of the progeny |
|
Definition
|
|
Term
which law is this?
each pair of alleles assorts independantly - so different combinations can occur in the progeny |
