Chapter 4 Jeopardy -8th Grade
Vocab 1
100- What are the various forms of the same gene called? Alleles
200- What is a special kind of cell division that produces haploid cells meiosis
300- T or F: inherited traits are traits you get from one or more parents through genes true
400- This takes place when sperm combines with an egg. Fertilization
500- This describes the genes that make up an organism. Genotype
Vocab 2
100-a ratio that compares a number to 100 percentages
200- This shows the relationship between two quantities. Ratio
300- A unit of heredity that occupies a specific place on a chromosome and codes for a particular trait
are called
genes
400- The actual traits (such as hair color, eye color ) that are expressed is called the ? Phenotype
500- During this, a cell containing genetic information from one parent combines with another cell
containing genetic information from the other parent to form a new cell. Sexual reproduction
Alleles R Us
100- an allele that is expressed even if only one copy is present in a genotype is ? Dominant
200- The allele that is expressed in the phenotype only when two copies of it are present on the
homologs is? Recessive
300- When Mendel crossed a regular height pea plant with a dwarf height pea plant and the first
generation was all regular height, which allele was dominant? Regular height
400- T OR F: correct if false: Each box in a Punnett square shows one possible allele from each parent.
true
Punnett Squares and Probability
100- T or F: if false, correct it: A Punnett square represents how the parents’ alleles always combine
in offspring. True or False? False, might combine
200- Finish this sentence. A complete Punnett square shows genotypes and phenotypes of parents and
________ . offspring
300- One parent has 1 dominant allele for tall T, and one for short t. The other parent has a tt
genotype. What is the probability the offspring will be tall? 50%
400- What are the chances that a human offspring will have an XY genotype? 1:2 or 50%
Meiosis and More
100- During Meiosis, how many times do cells divide? Twice
200-T or F: Only cells in reproductive tissues of an organism reproduce in meiosis. Answer T or F
and what is the name of these types of cells. True; gametes, 1n or haploid cells
300- What type and how many cells are the final products of meiosis? 4-1n cells
400- A 2 n human cell has 46 chromosomes. How many chromosomes does a female gamete have?
23
FINAL JEOPARDY
What are 4 differences between meiosis and mitosis?
Only cells becoming gametes go through meiosis; meiosis has 2 cell divisions and mitosis has 1 cell
division; daughter cells by meiosis contain half of genetic material of the parent cell; daughter cells by
mitosis contain exactly the same genetic material as the parent; in mitosis, chromosomes are always
copied before division; in meiosis, chromosomes are not copied before the second division.
