column a

1. gene
2. chromosome
3. phenotype
4. sex - linked trait
5. mutation
6. genetic disease
7. selective breeding
8. genetic engineering
9. carrier
10. heredity

column b
a determined by an organisms sex chromosomes
b organism that has a gene but does not show the effects of the gene
c the passing of traits from parents to offspring
d breeding plants and animals for a certain trait shown
e change in a gene
f information about a trait that a parent passes to its offspring
g caused by a mutated gene
h an organisms appearance as a result of its combination of genes
i rod - shaped structure found in the nucleus of a cell
j process of transferring genes from one organism

part b write the letter of the answer that correctly completes each sentence.

1. human genetics is the study of how humans inherit ______.

a chromosomes b traits c genes d mutations

1. an organisms surroundings is its ______.

a base b gamete c environment d genotype

1. color blindness is an example of ______.

a a genetic disease b mutation c selective breeding d a sex - li

1. ______ is the division of the nucleus into two new nuclei.

a meiosis b mitosis c heredity d libras

1. the group of all the genes found within a certain population is called a ______.

a gene base b gene pool c genesis d carri

Explanation:

Part A (Matching)

1. Gene: F (information about a trait a parent passes to offspring)
2. Chromosome: I (rod - shaped structure in nucleus)
3. Phenotype: H (organism's appearance from genes)
4. Sex - linked trait: A (determined by sex chromosomes)
5. Mutation: E (change in a gene)
6. Genetic disease: G (caused by mutated gene)
7. Selective breeding: D (breeding for certain trait)
8. Genetic engineering: J (transferring genes between organisms)
9. Carrier: B (has gene but no effect)
10. Heredity: C (passing traits from parents)

Part B (Multiple Choice)

1. Human genetics studies how humans inherit traits. So the answer is B.
2. An organism's surroundings are its environment. So the answer is C.
3. Color blindness is a genetic disease. So the answer is A.
4. Mitosis is the division of the nucleus into two new nuclei. So the answer is B.
5. The group of all genes in a population is a gene pool. So the answer is B.
