If a person inherited an allele with the same base substitution mutation from both parents, what sequences could be altered from normal in the person's cells?
meiosis
The parent is heterozygous for the trait.
1:1:1:1, in which 50% are tall, 50% dwarf, 50% pink and 50% white
Aabb, aaBb
Restriction enzymes and ligase
One mRNA base sequence and one polypeptide amino acid sequence only
Genes carried on the same chromosome
Sex chromosomes determine gender and autosomes do not.
A cross is performed between two organisms with the genotypes AaBb and aabb. What genotypes in the offspring are the result of recombination?
meiosis
The parent is heterozygous for the trait.
1:1:1:1, in which 50% are tall, 50% dwarf, 50% pink and 50% white
Aabb, aaBb
Restriction enzymes and ligase
One mRNA base sequence and one polypeptide amino acid sequence only
Genes carried on the same chromosome
Sex chromosomes determine gender and autosomes do not.
Which enzymes are needed to produce recombinant plasmids that are used in gene transfer?
meiosis
The parent is heterozygous for the trait.
1:1:1:1, in which 50% are tall, 50% dwarf, 50% pink and 50% white
Aabb, aaBb
Restriction enzymes and ligase
One mRNA base sequence and one polypeptide amino acid sequence only
Genes carried on the same chromosome
Sex chromosomes determine gender and autosomes do not.
Which process results in the greatest genetic variation in a population?
meiosis
The parent is heterozygous for the trait.
1:1:1:1, in which 50% are tall, 50% dwarf, 50% pink and 50% white
Aabb, aaBb
Restriction enzymes and ligase
One mRNA base sequence and one polypeptide amino acid sequence only
Genes carried on the same chromosome
Sex chromosomes determine gender and autosomes do not.
A parent organism of unknown genotype is mated in a test cross. Half of the offspring have the same phenotype as the parent. What can be concluded from this result?
meiosis
The parent is heterozygous for the trait.
1:1:1:1, in which 50% are tall, 50% dwarf, 50% pink and 50% white
Aabb, aaBb
Restriction enzymes and ligase
One mRNA base sequence and one polypeptide amino acid sequence only
Genes carried on the same chromosome
Sex chromosomes determine gender and autosomes do not.
What constitutes a linkage group?
meiosis
The parent is heterozygous for the trait.
1:1:1:1, in which 50% are tall, 50% dwarf, 50% pink and 50% white
Aabb, aaBb
Restriction enzymes and ligase
One mRNA base sequence and one polypeptide amino acid sequence only
Genes carried on the same chromosome
Sex chromosomes determine gender and autosomes do not.
What is a difference between autosomes and sex chromosomes?
meiosis
The parent is heterozygous for the trait.
1:1:1:1, in which 50% are tall, 50% dwarf, 50% pink and 50% white
Aabb, aaBb
Restriction enzymes and ligase
One mRNA base sequence and one polypeptide amino acid sequence only
Genes carried on the same chromosome
Sex chromosomes determine gender and autosomes do not.
If red (RR) is crossed with white (rr) and produces a pink flower (Rr), and tall (D) is dominant to dwarf (d), what is the phenotypic ratio from a cross of Rr dd and rr Dd?
meiosis
The parent is heterozygous for the trait.
1:1:1:1, in which 50% are tall, 50% dwarf, 50% pink and 50% white
Aabb, aaBb
Restriction enzymes and ligase
