Web18 dec. 2016 · IST-1.I.2. Fertilization involves the fusion of two haploid gametes, restoring the diploid number of chromosomes and increasing genetic variation in populations by creating new combinations of alleles in the zygote —. Rules of probability can be applied to analyze passage of single-gene traits from parent to offspring. WebMendel’s laws (principles) of segregation and independent assortment are both explained by the physical behavior of chromosomes during meiosis. Segregation occurs because each gamete inherits only one copy of each chromosome. Each chromosome has only one copy of each gene; therefore each gamete only gets one allele.

Parental genes are randomly separated to the sex cells so that sex cells contain only one gene of the pair. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization. canal wood mullins sc
