Human females have two X chromosomes (XX); males have one X and one Y chromosome (XY). a. With respect to X chromosome alleles, how many different types of gametes can a male produce? b. If a female is homozygous for an allele on an X chromosome, how many types of gametes can she produce with respect to that allele? c. If a female is heterozygous for an X chromosome allele, how many types or gametes can she produce with respect to that allele?

Human females have two X chromosomes (XX); males have one X and one Y chromosome (XY).

  1. a. With respect to X chromosome alleles, how many different types of gametes can a male produce?
  2. b. If a female is homozygous for an allele on an X chromosome, how many types of gametes can she produce with respect to that allele?
  3. c. If a female is heterozygous for an X chromosome allele, how many types or gametes can she produce with respect to that allele?

Summary Introduction

To determine: The different types of gametes a male can produce with respect to X chromosome alleles.

Introduction: In humans, somatic cells contain two copies of chromosomes and genes. The sex chromosomes that determine sex are X and Y, and other paired chromosomes are autosomes. Females have two X chromosomes, and males have an X and a Y chromosome. Genes exist in two alternate versions called as alleles. During meiosis, the alleles segregate into different cells forming gametes.
