Matching. Select the letter in front of the term that matches the statement. Type the “upper case” letter in the “answer” column. Use red font color.
Q
Term
Answer
Statement
1.
A. Allele
Process in sexual reproduction in which male and female reproductive cells join to produce a new cell.
2.
B. Fertilization
A specific characteristic of an individual.
3.
C. Gamete
One of a number of different forms of a gene.
4.
D. Gene
Offspring of crosses between parents with different traits.
5.
E. Hybrid
A sequence of DNA that codes for a protein and thus determines a trait; passed from parent to offspring.
6.
F. Principle of dominance
A sex cell, or a cell used for reproduction; egg or sperm.
7.
G. Segregation
Mendel’s second conclusion, which states that some alleles are dominant and others are recessive.
8.
H. Trait
Separation of alleles during gamete formation.
Multiple Choice. Change the font of the correct answer to RED.
Look carefully at the Punnett square below. The genotype in the blank box is
TT
Tt
tT tt Using the Punnett square from question 9 and Figure 11-4, page 311 in your textbook, determine the P generation cross. Question 9 is showing a cross between the F1 generation.
TT X TT
TT X tt
Tt X Tt tt X tt
Using the Punnett square from question 9 and Figure 11-4, page 311 in your textbook, determine the phenotypic ratio of the F2 generation.
½ Tall, ½ Short
¼ Tall, ¾ Short
¾ Tall, ¼ Short
All are Tall
Why did Gregor Mendel select the garden pea plant to do his study of heredity? The garden pea plants are small and easy to grow.
A single pea plant can produce hundreds of offspring.
In just one or two growing seasons, Mendel was able to carry out experiences that would have taken decades if studying humans.
All of these are correct.
