Answer:
Men express all the X-linked genes present in their genome.
Explanation:
Human males have one copy of X and one copy of Y chromosomes. They express all the alleles present on their X chromosome irrespective of its dominant or recessive nature. This occurs because males do not have a second copy of the X chromosome to carry another allele for the same gene. Color blindness is caused by a recessive allele present on the X chromosome. Males carrying one copy of this allele exhibit the disease while females need two copies of the allele of color blindness to express the disease. Therefore, males are more frequently affected by this disease.
<h2>Answer:</h2>
The correct options are 1,4 and 5. By looking at phylogenetic tree we can conclude this;
1. Species A and C may have shared features from a common ancestor.
4. Species B and E may have shared features from a common ancestor.
5. Species A is more related to species B than species B is related to species C

I believe the answer is none of these. The mousterian is defined by stone-knapping known as levallois. Mousterian burials are supported by morturt behavior and are not complex. The burials represented the individual who are singled out for treatment by mortuary. Most burials were done in caves and shelters where adults were mostly buried at the center.<span />
