Question

The image above shows a pair of homologous chromosomes with different alleles of the genes S and C. Lower case letters represent recessive alleles of the genes. This diploid individual's genotype is Ss Cc. a) State the genotypes of the haploid gametes that it is possible for this individual to produce if recombination is prevented from occurring. State whether these gametes are parental or recombinant (non-parental). [3 marks] b) Very briefly explain how the SsCc individual could produce both parental and recombinant (non-parental) gametes from a single meiosis. Indicate the genotype of the recombinant (non-parental) gametes. [3 marks]

Explanation / Answer

Genetypes of the haploid gametes without recombination will be SC or sc, as these gametes are haploid they should be parentel or not recombinant During meiosis if crossing over not occurs then gametes produced are called parental gametes and if crossing over and recombination of allele genes occurs then are called non parentel gametes. Genotype of the recombinant (non-parental) gametes will be SsCc
