Question

1. chromosomes carry ____________ which express specific

a. genes
b. information
c. dna
d. all of the above

1. the variance in a gene, which occur on a fixed spot or

a/an ________.
a. allele
b. cell
c. centromere
d. nucleus

1. on a punnett square two capital letters indicate a g

a. homozygous dominant
b. homozygous recessive
c. heterozygous
d. none of the above

1. probability in genetics is expressed in ____________.

a. equations
b. fractions
c. percentages
d. whole numbers

Explanation:

• Question 2: Chromosomes are made of DNA, which contains genes. Genes carry information. So chromosomes carry genes (which are made of DNA and carry information).
• Question 3: An allele is a variant form of a gene, and genes are located on chromosomes (a fixed spot on a chromosome).
• Question 4: In a Punnett square, two capital letters (e.g., \(AA\)) represent a homozygous dominant genotype.
• Question 5: Probability in genetics can be expressed as fractions (e.g., \(\frac{1}{4}\)) or percentages (e.g., \(25\%\)).

Answer:

1. D. All of the above
2. A. Allele
3. A. Homozygous dominant
4. B. Fractions, C. Percentages
