which combination of alleles are always involved in the inheritance of a sex - linked trait?\n○ heterozygous alleles\n○ homozygous alleles\n○ alleles that are carried on x and y chromosomes\n○ alleles that are carried on all chromosomes except the x and y chromosomes

which combination of alleles are always involved in the inheritance of a sex - linked trait?\n○ heterozygous alleles\n○ homozygous alleles\n○ alleles that are carried on x and y chromosomes\n○ alleles that are carried on all chromosomes except the x and y chromosomes

Answer

Answer:

C. alleles that are carried on X and Y chromosomes

Brief Explanations:

Sex - linked traits are determined by alleles on sex chromosomes (X and Y). Heterozygous and homozygous alleles are not specific to sex - linked inheritance. Alleles on non - sex chromosomes are for autosomal traits, not sex - linked.
