Since hemophilia is an X-linked recessive disorder, the probability depends on the X alleles. So, if father has dominant allele (H), the probability that a <span>female child would suffer from hemophilia (genotype: hh) is 0%, no matter of mother's genotype:
Father Mother Parents: H x Hh Daughter: HH or Hh
</span> Father Mother Parents: H x HH <span>Daughter: HH </span> Father Mother Parents: H x hh <span>Daughter: Hh or Hh </span> But, if the father has recessive allele, the probability that a <span>female child would suffer from hemophilia (genotype: hh) will depend on mother's genotype. If mother is dominant homozygous, there will be 0% of possibility: </span> Father Mother Parents: h x HH <span>Daughter: Hh </span> If mother is recessive homozygous, the possibility is 100%: Father Mother Parents: h x hh <span>Daughter: hh </span> If mother is heterozygous, the possibility is 50%: Father Mother Parents: h x Hh <span>Daughter: Hh or hh</span>
Tundras are the coldest places in the world and are located far north, around the arctic circle, and incorporates countries such as Finland, Russia, Alaska, and others.
