Question

This is what i got so far...

Section 1

1. What is an observable trait known as?
An observable trait is known as the phenotype.

2. What is the genetic make-up known as?
The genetic make-up or combination of alleles is known as the genotype.

3. How is a testcross?
A testcross breeds an individual of unknown, but dominant phenotype with a homozygous recessive individual.

4. What does the principle of independent assortment state?


5. What type of inheritance pattern is blood type an example of?


6. What type of inheritance pattern are height and skin color an example of?


7. What does “P” generation stand for?
P Generation stands for the parental plants (P for parental).

8. What is the word we use today that means what Mendel referred to as factors?
Today, Mendel's "factors" are called genes.

9. What type of diagram predicts the possible outcomes of offspring?
The Punnet Square

10. Which hypothesis stated that parents pass on to their offspring separate and distinct factors?

Section 2
Indicate whether each of the following is heterozygous or homozygous.

a. Rr - Heterozygous b. BB - Homozygous c. Jj - Heterozygous d. Kk - Heterozygous

e. Anthony’s mom has red hair and his dad also has red hair. Anthony has red hair. Is he a heterozygote or a homozygote?
-Homozygote

f. An organism that is considered homozygous and another that is considered heterozygous will have the same genotype or phenotype?
-Phenotype

g. A Mountain has 657 yellow flowers and 213 red flowers. Which color is the recessive trait? How is it represented? What are the possible genotypes for the flower?
- The recessive trait is the red flower. They are represented by

i. If “T” represents tan skin and “t” represents white skin, what are the phenotypes of the following?
* Tt - Tan Skin * tt - White Skin * TT - Tan Skin


Please tell me what i have wrong and help me with the ones i havent finished answering please?...thanks

Answer 1

4. The Law of Independent Assortment states that the way one pair of alleles separates into different gametes does not affect how another pair of alleles separates.
5. Blood type is an example of multiple alleles since the gene has three different alleles: IA, IB, and i (or A, B, and O).
6. Height and skin color are examples of polygenic inheritance since a range of phenotypes exist for these traits.
10. This idea is called the Rule of Unit Factors.

The others you have already answered are correct.
