Why are recessive X-linked traits seen more often in human malesthan in human females? (Select all that apply.)
Males have an X chromosome, but females do not.
Actually, X-linked traits are seen more often in females than inmales, because they have two X chromosomes.
Males donât have a second X chromosome to mask the effects ofthe first one.
This phenomenon is due to X-inactivation.
While females would need two of these alleles to express therecessive phenotype, males only need one.
Sperm are more likely to carry an X chromosome than a Ychromosome.
