Question 29 (Mandatory) (2 points) ? Listen Amanda is curious to know how many chromosomes are in each somatic cell of a chicken she was relishing. She looks it up and finds that it has 78 chromosomes. Therefore, a sperm or an unfertilized egg from a chicken would contain ____ chromosomes. 23 78 39 156 46

If the 2n number for chickens is 78, how many chromosomes would be present in a chickens sperm cell? What is the ploidy of this cell? 39 haploid 19 haploid 156 tetraploid 78 diploid

Humans, like Rebecca in the previous question, have 2 sets of chromosomes, in which 1 set is passed to the offspring. Humans have 46 chromosomes in total (23 pairs). Each human passes down 1 chromosome from each pair, so an egg or sperm contain a total of 23 chromosomes. Other organisms have different numbers of chromosomes. For ease, biologists represent 1 set of chromosomes from any organism by the letter n. Any cell with 2 sets is called diploid and represented as 2n. Any cell with just that 1 set (n) is called haploid. Two cells are isolated from a sexually reproducing organism. One cell contains 92 chromosomes and the other cell contains 46 chromosomes. Which of the following statements are true? a. The diploid number (2n) of this organism is 46 b. The diploid number (2n) of this organism is 92 c. The cell containing 46 chromosomes is likely a gamete (egg or sperm) cell from the organism d. The cell containing 46 chromosomes is likely a somatic (body) cell from the organism e. The cell containing 92 chromosomes is likely a somatic (body) cell from the organism
