BIOLOGY
Two sources of variability that arises during meiosis and fertilizations - CORRECT ANSWERS
1. Crossing over
2. Independent Assortment
Crossing Over - CORRECT ANSWERS homologous chromosomes pair... each sister chromatid
consists of a single stranded DNA molecule
What is the result of the crossing over between homologous chromatids? - CORRECT
ANSWERS The exchange of segments
Where do the homologous chromosomes separate? - CORRECT ANSWERS First meiotic
division
What is produced after meiosis II - CORRECT ANSWERS two daughter chromosomes have
parental combinations of alleles: A-B and a-b. And the other two daughter chromosomes are
recombinants for the alleles: A-b and a-B
Independent assortment - CORRECT ANSWERS refers to chromosomes splitting
what do a pair of chromosomes consist of in independent assortment? - CORRECT ANSWERS
one maternal chromosome and one paternal chromosome
In metaphase I, what occurs? (independent assortment) - CORRECT ANSWERS one of each
homologous pair is randomly attached to the spindle of each pole
The 23 chromosome pairs of humans allow... how many different combinations?... -
CORRECT ANSWERS 2^23 different combinations of maternal and paternal chromosomes
