How many types of gametes can be produced by a diploid organism who is heterozygous for 4 loci?
Options:
Answer:
Solution:
As per Mendel's law of segregation, "alleles segregate randomly into gametes: when gametes are formed, each allele of one parent segregates randomly into the gametes, such that half of the parent's gametes carry each allele."
Gametes are the reproductive cells produced by meiosis. These cells participate in the fertilization process to form the zygote. Gametes contain half the genetic content of the parent cell. Also, the genes/allele/loci segregate and recombine during the meiosis.
If an organism is heterozygous at four loci, for example Aa, Bb, Cc, Dd, then during meiosis, they get segregated to form 8 gametes. If the genes are not linked, then the diploid organism will produce 16 different gametes.
