quiz 4

Question 1

Mendel’s first law

Answer 1

law of segregation: two copies of a gene separate during meiosis, making gamete haploid

Question 2

Mendel’s second law

Answer 2

law of independent assortment: alleles of different genes assort independently of one another (inheritance of one trait does not influence inheritance of another)

Question 3

genes that do not follow the law of independent assortment are

Answer 3

linked genes

Question 4

hemizygous

Answer 4

single copy of a gene (typically on X chromosome)

Question 5

biallelic expression

Answer 5

both alleles are transcriped

Question 6

pleiotropy

Answer 6

one allele has multiple phenotypic effects

Question 7

epistasis

Answer 7

phenotypic expression of one gene is influenced by another gene

Question 8

polygenic traits

Answer 8

characteristics influenced by multiple genes

Question 9

monoallelic expression

Answer 9

only one of the two alleles is active in a cell, while the other is silenced

Question 10

metaphase checkpoint

Answer 10

cell cycle stops if chromosome is not attached to spindle
