What is a monohybrid cross?
|
|
- each parental homozygotes produces on kind of gamete - the F1 heterozygotes produce two kinds of gametes in equal proportions - this yields 2 phenotype
|
|
|
|
2.
|
what is a gene?
|
|
mendel's heritable factor. something that is passed on
|
|
|
|
3.
|
what are alleles?
|
|
dominant and recessive forms of genes
|
|
|
|
4.
|
what is homozygous?
|
|
when both alleles are identical
|
|
|
|
5.
|
what is heterozygous?
|
|
when two alleles of a gene are different
|
|
|
|
6.
|
in a genetic cross the parents are referred to as? their offspring represent? and their grand offspring represent?
|
|
P = parents F1= offspring first generation F2= offspring second generation
|
|
|
|
7.
|
what is Mendel's principle of dominance?
|
|
in a heterozygote, one allele may conceal the presence of another?
|
|
|
|
8.
|
what is Mendel's principle of segregation?
|
|
neither allele is typically changed by coexisting with the other in a heterozygote
|
|
|
|
9.
|
what is Mendel's principle of independent assortment?
|
|
the alleles of different genes assort/segregate independently of each other
|
|
|
|
10.
|
what are the steps of a dihybrid cross?
|
|
1 - each parental homozygote produces one kind of gamete 2 - the F1 heterozygotes produce 4 kinds of gametes in equal proportions 3 - this yields four phenotypes
