Chapter 11
Name____________________________
Sections 11:1-11:3
1) Describe the parents of the F1 and F2 generations for pea plant height?
2) What is the possible number of phenotypes visible in a trait inherited through: Mendellian Inheritance,
Co-dominance, Incomplete Dominance, multiple alleles (specifically human blood type), and polygenic
inheritance? Make sure you understand how each of these works in terms of the inheritance patterns.
3) Why did Mendel choose the pea plant to study in experiments?
4) Mendel’s “factor” is currently known as a(n) ______________________.
5) Does current science support Mendel’s ideas? Are his patterns predictable?
6) Know how to do a monohybrid cross
7) Understand a dihybrid cross
8) What is the relationship between an allele and a gene?
9) Be able to use and understand the following terms: heterozygous, homozygous, trait(characteristic),
allele, pure-line, hybrid, P1 generation, F1 generation, F2 generation, phenotype, genotype, dominant,
recessive, cross-pollination, self-pollination, heredity, genetics, fertilization,
10) Give two examples of how the environment affects genes?
11) What is the probability of choosing three queens in a row from a deck of cards if you replace the card
you choose each time (put your answer in terms of a %)
12) What does the Law of segregation tell us about inheritance? And the Law of independent assortment?
13) If a red flower and a white flower were crossed, what would the heterozygote offspring phenotype be if
the color was inherited through Mendellian Inheritance? Through Co-dominance? Through Incomplete
Dominance?
Sections 11:4
14) What is the purpose of meiosis?
15) How does the location of a gene on a chromosome affect inheritance?
16) Be able to understand the following terms: gametes, gonads, diploid, haploid, homologous chromosomes
17) What do (N) vs (2N) represent during meiosis?
18) Recognize homologous chromosomes, tetrads, chromatids and single chromosomes in a diagram of
meiosis
19) Between the Law of segregation and the Law of Independent Assortment, which one is best associated
with meiosis and why?
20) What are tetrads? How do they form? And when?
21) What is crossing over and when does it occur?
22) How is the end of meiosis different in a male vs a female human? (spermatogenesis vs oogenesis)
