The prefix mono- means "one." How does this apply to the key term monohybrid cross?
|
Involves one pair of contrasting traits.
|
|
|
|
What information does the third sentence tell the reader?
|
Only one trait was passed in.
|
|
|
|
Describe the offspring of a true-breeding white-flowering plant.
|
Cross-breeding two white flowers it would probably be white flowers.
|
|
|
|
What is the P generation?
|
Parental Generation- is the first two individuals that mate in a genetic cross.
|
|
|
|
What does the term F1 generation refer to?
|
The first offspring from a cross of two varieties in the P generation.
|
|
|
|
During the course of his experiment, Mendal studied traits in
|
C. three generations of plants.
|
a.one generation of plants.
b.two generations of plants. c. three generations of plants. d. more than five generations of plants. |

What did T. A. Knight discover?
|
Mating two flowers of different colors. found out that when cross breeding two purple flowers that sometimes you get a white with the group of purple flowers.
|
|
|
|
How did Mendel's scientific work differ from the work of T. A. Knight?
|
Counted the number of each kind of offspring and sanalyzed the Data.
|

|
What are three reasons that garden pea is a good subject for studying heredity?
|
1.The garen-pea has many traits that have two clearly different forms that are easy to tell apart.
2.The mating of the garden-pea flowers can be easily controlled because the male and female reproductive parts are enclosed within the same flower. 3. the garden-pea is small, grows easily, matures quickly, and produces many offsprings. |
|
|
|
4.A monohybrid cross is a mating that considers one pair of contrasting traits.
5.Cross-pollination assures that each variety of garden-pea is true-breeding. 6.The P generation consists of the first two individuals that are crossed in a breeding experiment. 7.In mendal's experiment in which he cross-pollinated two P generation plants that had contrasting forms of a trait, the F1 generation showed both forms of the trait. 8.The F2 generation in Mendel's experiment was obtained by cross-pollinating the F1 generation. 9.The F2 generation in Mendel's experiment showed both fomrs of the trait in a ratio of 1:1. |

If the allele for yellow peas is Y, the allele for the contrasting trait, green peas, is
|
y.
|
|
|
|
If Tt is the genotype of a plant, where T stands for tall and the recessive allele stands for short, its phenotype is
|
TT.
|
|
|
|
If tt is the genotype of a plant, where T stands for tall and the recessive allele stands for short, its phenotype is
|
tt.
|
|
|
|
What is the law of segregation?
|
States that the two alleles for a trait segregate when gametes are formed.
|
|
|
|
What is the law of independent assortment?
|
States that the alleles of different genes seperate independently of one during gamete formation.
