PENN FOSTER BIOLOGY: Genetics and Inheritance Questions and Answers Already Passed What is the basic unit of heredity? The gene What is the principle of segregation in genetics? Each individual has two alleles for each gene, which separate during gamete formation so each gamete carries only one allele. What does a Punnett square illustrate? The possible genetic combinations resulting from a cross between two parents. What is the difference between homozygous and heterozygo...

Homologous chromosomes - ANSWER Chromosomes that pair durng meiosis and are identical with respect to their genetic loci and centromere placement. Chromosomes in diploid cells exist in pairs, one from the mother and one from the father. Diploid - ANSWER containing two complete sets of chromosomes, one from each parent. Haploid - ANSWER having a single set of unpaired chromosomes Mitosis - ANSWER cell division in which the nucleus divides into nuclei containing the same number of chromos...

Two types of cell division in eukaryotes - Answer-Mitosis, Meiosis Meiosis produces - Answer-gametes (sex) Mitosis produces - Answer-somatic cells (non-stem, non-sex) Cell division in prokaryotes is called - Answer-Binary fission In binary fission, the parent cell... - Answer-...divides to create *clonal* daughter cells (identical to each other + parent cell) Mitosis is - Answer-the division of the nucleus cytokinesis is - Answer-the division of the cytosol + other organelles 3 Functions...
