346 357 species definition varies depending upon which species concept one holds The most general definition however is that a species comprises a group of similar individuals able to breed a. 5. th. Grade - Timber Ridge Elementary. Genes are found on tiny spaghetti-like structures called chromosomes . and . chromosomes are found inside . the cell nucleus.. In humans, a cell nucleus contains 46 individual chromosomes or 23 pairs of chromosomes (chromosomes come in pairs, remember? 23 x 2 = 46). Half of these chromosomes come from one parent and half come from the other parent.. Kyle . Stutts. . Sam . houston. state . university. Sex-Linked Characteristics. Objectives. Students will be able to:. Comprehend how inheritance plays a role in sex-linked genes. Explain the difference between sex- linked, limited, and influenced inheritance. Making melanin pigment. The . TYR. gene is just one of many genes on the human number-11 chromosome. . The . TYR. gene encodes a protein that functions as the enzyme, . tyrosinase. . This enzyme catalyses a step in the pathway that produces the pigment, . Warm Up:. What are the major differences between asexual and sexual reproduction?. Which form of reproduction results in greater genetic variation (differences)? Explain why.. Explain why animals that reproduce sexually will never be an exact copy of one of the parents?. 1. Family resemblance: your mother and father each contribute to your genetic makeup.. allele:. alternative version of a gene. 2. Family resemblance: your mother and father each contribute to your genetic makeup.. A regular human cell has 46 chromosomes: 44 autosomes, which come in pairs, and 2 sex chromosomes, which specify gender (XX for female and XY for male).. The pairs of autosomes are called "homologous chromosomes." One of each pair came from mom and the other came from dad. Homologous chromosomes have all of the same genes arranged in the same order, but with slight differences in the DNA sequences of the genes.. more markers and gene tests. G.R. Wiggans,. 1. . P.M.
