test crosses - ANSWERS-A cross of an individual having a dominant phenotype (but
unknown genotype- e.g., AA or Aa) with an individual that is homozygous recessive (aa)
P generation - ANSWERS-parent generation
F1 generation - ANSWERS-offspring of the P generation
F2 generation - ANSWERS-offspring of the F1 generation
factors - ANSWERS-genes; seperated during gametogenesis
allele - ANSWERS-alternate forms of the same gene that could occupy the same locus
genotype - ANSWERS-genetic makeup of an organism
phenotype - ANSWERS-observable characteristics of an organism (e.g. physical,
behavioral, physiological characterstics
What do we assume in genetic models? - ANSWERS-that there are no mutations
, locus - ANSWERS-the location of a given gene along the length of a chromosome.
The locus for a gene is identified by the number of the chromosome on which it is found
and its position on the chromosome.
loose linkage - ANSWERS-the farther apart the loci are, the more opportunity there is
for a break and a swapping of alleles to occur
tight linkage - ANSWERS-the closer two loci are, the less likely a chromosomal break
and exchange will occur between them
Which breakage is more likely to occur? - ANSWERS-loose linkage, because the
location of the alleles are farther apart
linked genes - ANSWERS-genes located on the same chromosome, 2 chromosomes
unlinked genes - ANSWERS-genes on different chromosomes, 4 chromosomes
Mendel's 1st law - ANSWERS-segregation of alternate factors ( summarized meiosis)
true-breeding - ANSWERS-term used to describe organisms that produce offspring
identical to themselves if allowed to self-pollinate
Dominant trait - ANSWERS-A genetic trait is considered dominant if it is expressed in a
person who has only one copy of the gene associated with the trait.(Capital)
Recessive trait - ANSWERS-a genetic factor that is blocked by the presence of a
dominant factor.(lowercase)
homozygous - ANSWERS-An organism that has two identical alleles for a trait (AA, aa)
heterozygous - ANSWERS-An organism that has two different alleles for a trait (Aa)
