Chapter 14 - Section 1

Question 1

Genome

Answer 1

full set of genetic information that an organism carries in its DNA

Question 2

What is a karyotype?

Answer 2

A karyotype shows the complete diploid set of chromosomes grouped together in pairs, arranged in order of decreasing size.

Question 3

Karyotype

Answer 3

micrograph of the complete diploid set of chromosomes grouped together in pairs, arranged in decreasing size

Question 4

Sex Chromosomes

Answer 4

one of two chromosomes that determines an individual’s sex

Question 5

Autosome

Answer 5

a chromosome that is not a sex chromosome; also called an autosomal chromosome

Question 6

What patterns of influence do human traits follow?

Answer 6

Many human traits follow a pattern of simple dominance.

Question 7

What patterns of influence do human traits follow? 2

Answer 7

The alleles for many human genes display codominant influence.

Question 8

What patterns of influence do human traits follow? 3

Answer 8

Because the X and Y chromosomes determine sex, the genes located on them show a pattern of influence called sex-linkage.

Question 9

Sex-Linkage Gene

Answer 9

gene located on the sex chromosome

Question 10

How can pedigrees be used to analyze human inheritance?

Answer 10

The information gained from pedigree analysis makes it possible to determine the nature of genes and alleles associated with inherited human traits.

Question 11

Pedigree

Answer 11

chart that shows the presence or absence of a trait according to the relationships within a family across several generations
