A woman has two alleles of gene M (M and m), and two alleles of gene N (N and n). Both genes are on the X chromosome. Below are some possible representations of her X chromosomes (#1, #2, etc). Each line represents one X chromosome. The dot (.) represents the centromere. Which of these representations correctly show(s) the possible locations of these genes and alleles? Choose one or more. #1 _N___________ m. #2 #3 #4 #5 M n M N ΣΕ ΣΕ Σ m _n_____________ n_._ N N_____ _M_m__N n_._ B. This woman's two X chromosomes are i. Homologs ii. Sister chromatids iii.

Question
A woman has two alleles of gene M (M and m), and two alleles of gene N (N and n). Both genes are on the X chromosome. Below are some possible representations of her X chromosomes (#1, #2, etc). Each line represents one X chromosome. The dot (.) represents the centromere. Which of these representations correctly show(s) the possible locations of these genes and alleles? Choose one or more. #1 N m #2 #3 #4 #5 M n M N M m M m m n n_._ N_ N _M_m__N n__. B. This woman's two X chromosomes are i. Homologs ii. Sister chromatids iii. Non-homologous to each other. Choose one. C. How many copies of each allele of gene M are found in a cell that is in G2 phase? Number of copies of allele M:_ Number of copies of allele m:_ SMAR f D. During one mitosis event, the cohesin at the centromere of one X chromosome is cut early, before metaphase. Does this increase the likelihood of producing a daughter cell with three X chromosomes instead of two? Briefly explain your reasoning. 1 2
