3. Your friend is studying a newly discovered species of lizard. She obtains the following karyotypes for a female (left) and a male (right). How do you think that sex is determined in this species? 2points) 398 89 83 % K® 88 XX %% %% 38 && 26 8 8 38 x do **** 4. You are working on a certain species of worm, with an XX/XY sex determination system. You perform karyotype analysis for a mating pair, but you don't know which one is the male and which one is the female. Which one would you guess is the female (left or right?) (2points) ) 15

Answer 1

3. I think the sex determination pattern in this lizard species is XO/XX type in which the male has two Xc and the female has single X chromosome. As it can be seen from the karyotype that only X chromosome is present in the female.

4. In the karyotype for the worm species, the right karyotype appears to be for female as it has two sex chromosomes of approximately the same size while in the left image it is hard to see two chromosomes so may be due to unclear image, I can still predict one X and another Y chromosome in the left karyotype.
