What is always the difference between the alleles of a gene?
What is always the difference between the alleles of a gene?
- Their position on the chromosome
- Their amino acid sequences
- The number of codons that each contains
- Their base sequence (correct)
What is the difference between autosomes and sex chromosomes?
What is the difference between autosomes and sex chromosomes?
- Autosomes are diploid and sex chromosomes are haploid
- Sex chromosomes determine gender and autosomes do not (correct)
- Autosomes are not found in gametes but sex chromosomes are
- Sex chromosomes are found in animal cells and autosomes are found in plant cells
A parent organism of an 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?
A parent organism of an 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?
- The parent is heterozygous for the trait (correct)
- The trait being inherited is polygenic
- The parent is homozygous dominant for the trait
- The parent is homozygous recessive for the trait
A polygenic character is controlled by two genes each with two alleles. How many different possible genotypes are there for this character?

A single gene in humans causes blood to be either rhesus positive (dominant allele) or rhesus negative (recessive allele). A woman with rhesus-negative blood has already had a child with rhesus-positive blood. There could be complications during pregnancy if she has another child with rhesus-positive blood. What is the probability of this, if the father is the same, and if his mother is known to have rhesus-negative blood?
