chromosome theory of inheritance. Explain the chromosomal basis of the laws of segregation and independent assortment -The chromosomal theory of inheritance states that genes are located on chromosomes and that the behavior of chromosomes during meiosis and fertilization accounts for inheritance patterns. Mendel’s chromosomal basis of the law of segregation occurs when the two alleles

DIVISION RHODOPHYTA (RED ALGAE) RHODOPYTA (RED ALGAE) Red algae have been the 1st eukaryotes formed by endosymbiosis involving photosynthetic prokaryotes. Red algae are mostly multicellular It exhibit some of the most complex life cycles It posses cellulose walls‚ chlorophyll a‚ some posses chlorophyll d (chloroplast is present but lacks grana) Contains phycoerythrin‚ phycocyanin and allophycocyanin as accessory pigments. flagella is absent in red algae as well as centrioles 5‚000 species(approximate

chose should the cloning be successful. The procedure was performed by taking a dog’s egg cell‚ removing the nucleus‚ and then replacing it with the deceased dog’s DNA. It is then electrically stimulated in order to trigger it to begin undergoing meiosis. Tarantola’s journey to get Double Trouble started when she was 18 and she got a lovable mutt she named Trouble. She was so enamored with her new puppy‚ she painted Trouble’s face on a wall in her house‚ printed his face on her pillows and on her

is a genetic disorder that effects development in women‚ per TurnerSyndrome.Org. Women who have Turner Syndrome have one X Chromosome instead of two full X Chromosomes that most females are born with. One of the X chromosomes are “dropped” during Meiosis‚ when the sex cells divide to form eggs in females. It is not usually inherited. Turner Syndrome can affect the development of several body systems in those who have them. Turner Syndrome is believed to be a random error during the formation of eggs

1.} The items on the left side of my ISN that I think is my best work is on pages 9‚ and 21. The reason why I chose page 9 is because it was the steps of meiosis‚ and tis chart of the phases really helped me understand what undergoes in a cell during all of the phases. This reflected in me knowing and understanding the steps much better. Page 21 is titled Getting variation into a population. The main reasons I chose this is because it reflected the knowledge of how mutations change in genetic code

abnormalities. Patau’s occurs in about 1 in 16‚000 infants. Women of all ages have a chance of giving birth to a child with this condition‚ but the risk increases as the woman gets older. Trisomy 13 is caused by the nondisjunction of chromosomes during meiosis and sometimes translocation‚ the rearrangement of genetic material between chromosome 13 and another chromosome. Individuals with Patau’s syndrome often have heart defects‚ brain or spinal cord abnormalities‚ very small or poorly developed eyes‚ extra
