10. (B) Demonstrates the law of independent assortment
In his work on pea plant, Mendel proposed 2 laws- Law of segregation and Law of independent assortment. According to law of independent assortment the two traits of plant like- plant height and seed coat color are inherited independent of each other. Short and tall plants can have yellow or green color seed coat.
10) In his work on pea plants, Mendel found that plant height was inherited independently of...
I posted this question before but no answer I need to submit in 4 hours, please help. Although the following scenario is hypothetical, it is based on actual facts. Sickle cell anemia is an inherited form of anemia. Those with sickle cell anemia do not have enough healthy red blood cells to adequately carry oxygen to all the cells in their body. Normal red blood cells are flexible and round, and can easily move through the blood vessels. However, in...
1). The genotypes have an associated fitness values which we described in class as (1 1 1-s) for directional selection, (1 1-s 1) for disruptive and so on. In each of the examples below, write out the expected fitness values for AA,Aa, aa. Note that determining whether fitness for the heterozygote Aa is dominant or not is part of the question. All examples assume no other agent of evolution unless specified or required. Example: AA Aa aa Answer: 1 1-s...
Q 11. Which of the following statements is TRUE about Sickle cell anemia? (A) It is caused by a genetic mutation in the beta-hemoglobin gene. (B) It confers heterozygote advantage against malaria (C) It results in abnormal, sickle-shaped erythrocytes. (D) All of the above. Q 12. Which of the following explains why a deleterious allele may persist in a population? (A) Random genetic drift (B) Balancing selection (C) Negative selection (D) Random genetic drift or balancing selection Q 13. Which...
QUESTION 2 Climate change is a threat to the existence of many species. Which of the following limits to natural selection hinders the adaptation of species to the new climate conditions? The developmental plans of plants and animals are too complex. They cannot cope with the warmer temperatures. Mutations happen so frequently that beneficial alleles change before natural selection can substantially increase their frequency Many species not have gene variants in their gene pool that are beneficial in higher temperatures. Climate change happens so...
