Who is recognized as the father of genetics?

Which term describes a variant form of a gene?

What is the genetic state of true-breeding individuals?

What type of cross involves individuals that are heterozygous for two traits?

Which chromosomes are responsible for determining the sex of an individual?

What type of genes are primarily responsible for maintaining cellular activities?

Which term refers to a change in the sequence of bases in DNA?

How many nitrogenous bases are held together in a base pair?

Which type of RNA is responsible for transporting amino acids to the ribosome?

Pleiotropy refers to a situation where a single gene influences multiple traits. Which option correctly describes this concept?

During meiotic division, how many alleles does one parent contribute to a single gamete?

Which of the following describes chromosomes that are not involved in sex determination?

What is the term for the genetic process in which a fragment of one chromosome is attached to a nonhomologous chromosome?

Which chart displays genetic relationships among family members over multiple generations?

At which stage of meiosis does the independent assortment of chromosomes take place?

What is the process by which ribosomes synthesize proteins from mRNA?

Chapter 9: Mendelian Genetics

Gregor Mendel is the father of genetics.
An allele is a variant form of a gene.
True-breeding individuals have a homogenous genotype.
Individuals with two copies of the same allele are homozygous.
A dihybrid cross involves individuals heterozygous for two traits.
Pleiotropy is when a single gene affects multiple traits.
One parent contributes one allele to a gamete.
Punnett squares predict offspring outcomes (not perfectly accurate).
A heterozygous parent and a homozygous recessive parent could predict 50% homozygous recessive offspring.

Chapter 10: Chromosomes and Inheritance

Sex chromosomes determine sex.
Genetic disorders can arise from mutations in multiple genes.
New allele combinations result from crossing-over, random fertilization, and independent assortment.
Pedigrees are used to study inheritance patterns in families.
The father determines the sex of a child.
Autosomal chromosomes are non-sex chromosomes.
Translocation is the movement of a chromosome segment to another chromosome.
A pedigree displays family relationships and genetic traits.
Independent assortment occurs in Metaphase I of meiosis.

Chapter 11: DNA Structure and Repair

Housekeeping genes maintain cellular functions.
DNA repair processes include removal and replacement of damaged bases.
A mutation is a change in the DNA sequence.
A base pair consists of two nitrogenous bases, held together by hydrogen bonds.
Transcription is converting DNA to RNA.
mRNA delivers genetic information to ribosomes.
Translation converts mRNA into proteins at the ribosomes.

Chapter 12: Protein Synthesis

AUG is the start codon.
UAG is a stop codon.
DNA is single-stranded, RNA is single-stranded.
Types of mutations include insertions, deletions, and substitutions, not addition.
tRNA transports amino acids to the ribosome.
