Beyond Mendel

Question 0

Nondisjunction

Answer 0

Abnormal numbers of chromosomes usually occurring during meiosis

Question 1

What is chromosome mutation?

Answer 1

Mutation that affects a group of genes or an entire chromosome

Question 2

Simple dominance

Answer 2

If you have the dominant allele you will express the trait

Question 3

Simple recessive

Answer 3

Must have 2 recessive alleles to express the trait

Question 4

Incomplete dominance

Answer 4

A condition in which 1 allele is not completely dominant over another. The third (new) phenotype appears I. Heterozygous

Question 5

Codominance

Answer 5

Condition in which both alleles are expressed in the heterozygote.

Question 6

What did Mendel’s principles of genetics NOT do?

Answer 6

Traits controlled by two or more genes

Question 7

Polygenic traits

Answer 7

Traits controlled by 2 or more genes. Have a wide variety of phenotypes

Question 8

Multiple allele

Answer 8

When there is more than two possible alleles for a trait.

Question 9

Sex chromosomes

Answer 9

Each gamete the egg has receive a X. Where as sperm gamete can either receive an X or Y

Question 10

Sex-linked traits

Answer 10

Genes that are carried on either the X or Y chromosome

Question 11

X-linked traits

Answer 11

Linked on the x-chromosome
