Rule of Segregation Only one gene of the two alleles that you have is put into each gamete that you make. Alleles are located on homologous chromosomes, and since homologous chromosomes are segregated during meiosis, the genes are also segregated. Numerous gametes are formed during gamete production, and if the alleles are different (heterozygous), 50% of the gametes will carry one gene and 50% of the gametes will carry the other. When alleles are the same (homozygous), 100% of the gametes will carry the same allele. 1. A parent possesses two copies of each gene. When this parent passes on its alleles for a gene, how many does it contribute to each of the offspring? 2. How many copies of a gene does the other parent contribute to each offspring? 3. How many copies of each gene for the trait does each offspring receive?

Hi, could your please answer this question? I'm so confused. The following diagram (picture added) shows 2 pairs of autosomal chromosomes in a karyotype of a biological woman. Based on the karyotype, a genetic counselor determined that there is evidence that a translocation occurred between two non-homologous chromosomes. The other 21 pairs of chromosomes are NOT shown in this diagram. Assume no chromosomal aberrations occurred in the other chromosomes. As a student-researcher, what would be your answer if the genetic counselor asks you if you can determine whether the translocation occurred in a somatic cell, germ-line cell, or whether this can even be determined from the figure? provide the reasoning for your answer.
