Figure 8.2: Male vs Female fruit flies The flies in the image below are your ACTUAL data for the sex-linked cross in your lab. Determine both the sex and eye color of each fly and write it as the actual ratio in the lab when asked.

Please , if you don’t know the answer just don’t solve it , I don’t want from google or from websites .

Concept map

Gametes of pureline diploid organisms are_____________________ (please select all correct answer options).   have one copy of each gene in the genome   heterozgyous   homozygous   haploid

Do all and label so I know which answers to which

ANALYSIS:Read the following scenarios. Based from the information given, give the specific phase of the cell cycle being described (this includes the interphase, and phases under mitosis and meiosis). USE ONLY CAPITAL LETTERS IN ANSWERING. Anthony noticed from the same interactive presentation that in this phase, tetrads line up in the middle of the cell facing each pole.

Please see instructions and exmaple. It should only be one big map.

please explain this question to me. Also, even though we get 96 in the second option, why is it wrong? help me please

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?…
