Choose the correct answer:
1-What is the reason that closely linked genes are typically inherited together?-A
They are located close together on the same chromosome.
The number of genes in a cell is greater than the number of chromosomes.
Alleles are paired together during meiosis.
Genes align that way during metaphase I of meiosis
 
2-What is a syndrome?-C
a characteristic facial appearance
a trait that leads to cancer at some stage in life
a group of traits typically found in conjunction with a particular chromosomal aberration or gene mutation
a specific characteristic that appears in conjunction with one specific aneuploidy
 
3- Mendel continued some of his experiments into the F2 or F3 generation to B_____.
obtain a larger number of offspring on which to base statistics
observe whether or not a recessive trait would reappear
observe whether or not the dominant trait would reappear
distinguish which alleles were segregating
4- Mendel accounted for the observation that traits that had disappeared in the F1 generation reappeared in the F2 generation by proposing that _____.
new mutations were frequently generated in the F2 progeny, "reinventing" traits that had been lost in the F1
the mechanism controlling the appearance of traits was different between the F1 and the F2 plants
traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1
members of the F1 generation had only one allele for each trait, but members of the F2 had two alleles for each trait
