Chapter 14: Mendel and the Gene idea

Question 1

What are the two inheritance theory

Answer 1

Blending Theory and Particulate Theory

Question 2

Blending Inheritance

Answer 2

Genes blend and mix

Question 3

Particulate Inheritance

Answer 3

Traits are inherited based on defined principles

Question 4

Why Mendel choose the Pea Plants for his experiment

Answer 4

• Short amount of time
• Give a large offsprings
• Can be self-pollinate or cross-pollinate
• Have distinct characters (colors, shape) and traits.

Question 5

True-breeding

Answer 5

Plants that through many generations of self-pollination still produce the offsprings that have the same variety as the parents.

Question 6

Hybridization

Answer 6

The breeding of two opposite species

Question 7

“P generation” stands for

Answer 7

Parental generation

Question 8

“F1” stands for

Answer 8

First filial generation

Question 9

F2 stands for

Answer 9

second filial generation

Question 10

Allele

Answer 10

Alternate forms of genes

Question 11

Heterozygote

Answer 11

Two different alleles at a locus

Question 12

Homozygote

Answer 12

Two similar alleles at a locus

Question 13

Is homozygous or heterozygous true-breeding

Answer 13

Homozygous because it has two similar alleles.

Question 14

Phenotype

Answer 14

Observable traits

Question 15

Genotype

Answer 15

Genetic makeup

Question 16

Law of segregation

Answer 16

During gametes, each of the alleles from each heritable traits separate and end up in different gametes.
