final Flashcards
1
Q
gene
A
2
Q
allele
A
particular form of a gene
-different alleles have different DNA sequences
-an individual is diploid, meaning they can only have 2 alleles for a gene
3
Q
locus
A
stretch of DNA at a particular location on a chromosome
4
Q
meiosis
A
produced haploid gametes
-dna must be replicated for cells to undergo meiosis
5
Q
metaphase I of meiosis I
A
- 1 pair of homologous chromosomes –> one comes from one parent, one comes from the other –> DNA replication occurs
homologous chromosomes & their respective sister chromatid line up in the middle and form a bivalent/tetrad
6
Q
anaphase I of meiosis I
A
homologous chromosomes separate (still bound to sister chromatids)
7
Q
metaphase II of meiosis II
A
line up in the middle
8
Q
anaphase II of meiosis II
A
sister chromatids separate –> 4 haploid gametes
