Answer #1

In genetics locus is a specific fixed position on a chromosome where a particular gene or gene marker is located. The order list of loci for a a particular genome is called as gene map. Gene mapping is the process of identifying a specific locus responsible for particular phenotype or biological trait. Two types of gene mapping are

1) Genetic mapping

Linear description of genes and markers on a given chromosome with maekrrs closer being inherited together often.

2) Physical mapping

Location of genes on chromosomes using cytogenetics and physical methods.

"The orange locus in cats is located on the X chromosome. In females, XoXo results in orange cats and X+X+ results in black cats When a female is heterozygous XoX+, they express both colors in patches due to a phenomenon called X-inactivation in which one X in every cell is inactivated. These females are called calico or tortoiseshell, depending on the presence of white spots. Male cats are either orange (XoY) or black (X+Y). A cross between a black female...

Consider a population in which heterozygotes at a certain locus (gene) have much larger bodies than homozygotes of either allele. This large body size results in a selective advantage. What type of selection is this: disruptive, stabilizing, or directional? Explain your answer.

Suppose that the leaf color of a certain plant is controlled by one gene locus with two alleles. At this locus the G allele is associated with orange color and is dominant to the g allele, which is associated with green color. You have a plant with orange leaves, but do not know whether that plant's genotype is GG or Gg. Which of the following would help you determine the plant's genotype? Cross two true-breeding, orange-leaved plants to each other...
