A human zygote (a fertilized human egg) has an abnormal sex chromosome genotype of XO meaning that the zygote only has a single X chromatid and no other sex chromosomes. This abnormal genotype could have resulted from (note: to earn full credit you must correctly select ALL that are possible for resulting in an XO zygote). -a single nondisjunction event in meiosis I in the female parent -a single nondisjunction event in meiosis II in the female parent -a single...

Cats have 38 chromosomes in their somatic cells and use the Lygaeus mode of sex determination. How many chromosomes does a cat receive from its father? How many autosomes are present in a cat gamete? How many sex chromosomes are there in a cat sperm? d. How many autosomes are there in a somatic cell of a female cat? e. If a diploid cell contains 12 chromosomes, how many potentially genetically distinct gametes can be formed?
Description Human chromosomes are classified as either autosomes or sex chromosomes, and the inheritance patterns of traits vary depending on the type of chromosome they are located on. Why is this the case? Instructions Read Chapter 5 in Essentials of Genetics, then respond to the prompt below: Prompt: In humans (and most animals), sex is determined using the X-Y system. The basis of this system is that the number of X chromosomes and Y chromosomes determines whether the individual will...
