Genes and Alleles

Genes and Alleles starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Genes and Alleles.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A man with genotype Aa marries a woman with genotype aa. What is the probability that their child will be homozygous recessive?
A person with genotype IAIB for the ABO blood group system will have which blood type?
A woman with genotype IAi and a man with genotype IBi have a child. What are the possible blood types of their child?
Describe how environmental factors can influence the expression of genes.
Describe the concept of pleiotropy.
Describe the relationship between dominant and recessive alleles.
Explain the concept of codominance and give an example.
Explain the difference between a dominant and a codominant allele.
Explain the difference between autosomal and sex-linked genes.
Explain the law of segregation.
If a gene has three alleles, how many possible genotypes can be formed?
In Mendel's pea plant experiments, the allele for tall plants (T) is dominant over the allele for short plants (t). What is the phenotype of a plant with genotype Tt?
What is a carrier in terms of genetics?
What is a gene?
What is meant by the term 'multiple alleles'?

What is the difference between genotype and phenotype?
What is the expected phenotypic ratio in the F2 generation of a monohybrid cross involving complete dominance?
What term describes the location of a gene on a chromosome?
