Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

More Crosses with Pea Plants: The Principle of Independent Assortment In pea plants, long stems are dominant to short stems, purple flowers are dominant to white, and round peas are dominant to wrinkled. Each trait is determined by a single, different gene. A plant that is heterozygous at all three loci is self-crossed, and 2,048 progeny are examined. How many of these plants would you expect to be long stemmed with purple flowers, producing wrinkled peas?

In an attempt to simplify meiosis for the benefit of students, mad scientists develop a way of preventing premeiotic S phase and making do with having just one division,including pairing, crossing over, and segregation.

Hi, I'm having some trouble with this practice problem from my study guide. If anyone can explain it it would be very helpful! Sometimes nondisjunction will occur in a parent that has normal chromosome numbers and result in an offspring that has abnormal number of chromosomes. The phenotype of the affected offspring will often allow geneticists to determine in which parent and during which division of meiosis the nondisjunction occurred. In each of the examples below, assume the parents have a normal diploid chromosome complement. A man with the X-linked dominant condition “brown tooth enamel” and a woman with normal tooth enamel produce a son with brown tooth enamel. Let’s call the allele for brown tooth enamel “XB” and normal tooth enamel “Xb”. EXAMPLE 1: The parents in the family above produce another son, this time with two Y chromosomes and normal tooth enamel. In which parent did the nondisjunction occur? Explain and/or illustrate. Did nondisjunction occur at meiosis I or II?…

In mammals, there are two sex chromosomes, X and Y, which behave like homologous chromosomes during meiosis. Normal males have one X chromosome and one Y chromosome, and normal females have two X chromosomes. Males with an extra Y chromosome (XYY) occasionally are found due to inappropriate segregation of the chromosomes (i.e. non-disjunction). Which of the following could give rise to such an XYY male? Answer Yes or No for each situation. nondisjunction in the first meiotic division of spermatogenesis; normal meiosis in the mother nondisjunction in the second meiotic division of spermatogenesis; normal meiosis in the mother nondisjunction in the first meiotic division of oogenesis; normal meiosis in the father nondisjunction in the second meiotic division of oogenesis; normal meiosis in the father
