Hello!
I m studying for one test from genetic, and stop at one subjectcalled as Pedigree analysis...I was looking to find the bestanswers to make clear my mind but it is hard to me so hear is theproblems:
-When they ask what type of condition is this: Is it DOMINANT orRECESSIVE how can I get answer on this....IS IT TRUE THAT THE BESTWAY IS TO LOOK DOES CONDITION PASS GENERATION FOR EXAMPLE THATPARENTS ARE NOT AFFECTED BUT THEIR OFFSPRIGS ARE AFFECTED WE CANSAY THAT CONDITION IS RECCESIVE, BUT IF CONDTION DO NOT PASSGENERATION WE CAN SAY THAT CONDITION IS DOMINANT FOR EXAMPLE IF ONEOF PARENTS IS AFFECTED AND HAVE AFFECTED OFFSPRINGS?
-When they ask is the condition: SEX-LINKED or AUTOSOMAL how can Iget answer on this...IS IT TRUE THAT WE MUST SEE HOW MANY SEX ISAFFECTED....IF JUST ONE IS AFFECTED MOSTLY MALE WE CAN SAY THATCONDITION IS SEX-LINKED BUT IF BOTH SEX FEMALE AND MALE AREEFFECTED WE CAN SAY SIMPLY THAT CONDITION IS AUTOSOMAL.
Pls if anyone can tell me did i correct understand this pedigreeanalysis if not pls correct me....THANK YOU A LOT!

6) A long winged male crow with a head ruff mates with a short winged crow without a head ruff. All of their male offspring have long wings, half of them have a head ruff and half lack a head ruff. All of the female offspring have long wings and half have a head ruff and half do not. A) Are either of these genes sex-linked? B) What is your reasoning? C) What is the most likely genotype for each parent and type of offspring? (4 pts)
What would be a key for this problem
Long winged male crow
Head ruff
Short winged female crow
No head ruff
Is this the correct way to do this and Are either of these genes sexed linked
What is your reasoning
Genotype for parents
Long winged male crow with a head ruff = ZLrZLR
Short winged female crow without a head ruff = ZlrW
Genotype for offsprings
½ Male offspring have long wings and a head ruff = ZLRZlr
½ Male offspring have long wings without a head ruff = ZLrZlr
½ Female offspring have long wings and a head ruff = ZLRW
½ Female offspring have long wings without a head ruff = ZLrW
ZLr | ZLR | |
Zlr | ZLrZlr | ZLRZlr |
W | ZLrW | ZLRW |
Are either of these genes sexed linked
What is your reasoning
Ask this question several times still do not understand how do you know is? Is there a way to explain it in everyday words.
10) Hunchback serves as a silencer protein for the gene encoding Ultrabithorax. A) Which of these two genes is epistatic to the other? B) How do you know? received several scientific answers that I do not understand.
Epistasis is a form of gene interaction in which one pair of genes masks or hides the phenotypic expression of another. Hunchback (hb) gene is epistatic to Ultrabithorax (Ubx) gene.
Thank you very much. I would appreciate it if you can answer both. Do not have many questions remaining to ask for the month.
