Over Prophase 1 & Prophase 2 and independent Assortment in Prophase 1 only Sperm fertilizing erg in Telophase 2 and zygote formation after Cytokinesis 2 Question 3 1 pts Pg 99. Why is it essential that each gamete receive only one set of chromosomes, in other words. why must gametes be haploid? Because a haploid gamete can then fuse with a diploid egg or diploid sperm which promotes fertilization and development of a zygote. Because when gametes fuse in fertilization,...
Without crossing over, the independent assortment of the homologous chromosomes in a cell with these chromosomes will produce two different genotypes. Which are they? without produce we gw the dependentm ent of the homologous commence with these chromosomes n t types which are they XX ORT, Rein
if an organism is diploid or 2n number of 16 how many chromosomes do its sperm cells or eggs contain?
Can you help me with this problem: 5. In an organism where 2N = 20, how many unique gametes could be produced due to independent assortment alone (not considering crossing over)? Briefly explain. 6. One of the autosomal loci controlling eye color in fruit flies has two alleles, one for brown eyes and the other for red eyes. Fruit flies from a true-breeding line with brown eyes were crossed with flies form a true-breeding line with red eyes. The Fı...
Here are data from crossing a phenotypically wild-type female Drosophila (tly) F1 The Y and A genes are dosely linked on the same chromosome. In this cross, which of the following is true about the gametes produced by the F1 progeny 2 pt YYAA X Yaa YyAa A. YA & Ya gametes will outnumber YA & ya gametes. B. YA & ya gametes will outnumber yA & Ya gametes. C.YA. Ya, YA, & xa gametes will be present in equal...

Draw the diagrams showing Metaphase I and Metaphase II for this organism. 10 B. A haploid set of unreplicated chromosomes of the above organism has a mass of 1.5 pg (picogram). What is the mass of DNA in single Aedes albopictus cell in prophase I and prophase II? C. Through independent assortment alone, how many...
3. Explain the importance of the reduction division, crossing over and independent assortment Introduction Write a short paragraph complaining the purpose of Mclosis and contrast it with the purpose of Mitosis. Then give the ways in which the chromosomal movements in Melosis and Mitosis are similar, and the ways h which they are different button store locomo Mno Understanding the Reduction Division. Draw the products of the each of the two divisions below (do not worry about independent assortment or...
12. A diploid organism has a total of 24 chromosomes. Assuming all possible chromosome combinations are viable: If a mutant tetraploid version of this organism was created how many chromosomes would it have? If a mutant version of this diploid organism was monosomic for chromosome 9 how many chromosomes would it have? A. 96; 25 B. 96,23 C. 48,23 D. 48; 25 In a diploid organism 2n = 6, and there are two long, two intermediate, and two short chromosomes....
1) An organism has 2n = 6 chromosomes with alleles A B / a b on the chromosome 1 homologous pair, alleles D / d on the chromosome 2 homologous pair, alleles E F / e f on the chromosome 3 homologous pair. Show two different ways that chromosomes could align at the metaphase plate during Meiosis I (show the chromosomes and alleles). Assume no crossing over. How many combinations of chromosomes are possible in the gametes? Please show me...
