- c the genetic makeup of an organism
- d One of Mendel's principles that states that genes for different traits can segregate independently during the formation of gametes
- e Chromosome pairs of the same length, centromere positions, and staining patterns for the same characteristics.
5 Multiple choice questions
- The diploid cells of most adult organisms contain two complete sets of inherited chromosomes and so two complete sets of genes.
- states that some alleles are dominant and others are recessive
- states that genes for different traits can segregate independently during the formation of gametes
- The principle of independent assortment states that genes for different traits can segregate independently during the formation of gametes
- The trait is visible whenever a dominant allele is present in the genotype such as TT or Tt(both tall)
5 True/False questions
Crossing-over → process in which homologous chromosomes exchange portions of their chromatids during meiosis
Prophase I → meiosis I results in two haploid daugther cells, each with half the number of chromosomes as the original cell
If an organism's diploid number is 46, what is the number for haploid? → 23
Homologous → term used to refer to chromosomes in which one set comes from the male parent and one set comes from the female parent
Why are the principles of probability used for genetics? → They predict the traits of the offspring of the genetic crosses.
