iVinArrow [24]

The chromosome number 23 is the sex chromosome also responsible for colorblindness. As it is sex linked the son can receive the recessive allele from the mother.

LekaFEV [45]

Answer:

Opportunistic, endogenous pathogen

Explanation:

Opportunistic infection is an infection that is caused by the microbes that are otherwise the component of one's own normal microbiota.  Under particular conditions, the microbes become pathogenic and cause infection. The pathogen-derived from one's own microbiota is called endogenous pathogen.

According to the given information, <em>Candida albicans </em>is a part of the microflora of mouth but becomes pathogenic under certain conditions. In healthy individuals, they do not produce disease as their overgrowth is suppressed by other microbiota and other host resistance mechanisms. The infection occurs only in those individuals with predisposing factors such as weakened immune system or after consumption of antibacterial medications that disturb the normal microbiota and immune competency. This makes it an opportunistic, endogenous pathogen.

JulsSmile [24]

Answer:

They are co-dominance and incomplete dominance.

<h2 />

Explanation:

Co-dominance occurs when both alleles in a heterozygous genotype for a trait are both equally expressed. An example is the human AB blood group, in which both the A and B alleles are equally expressed.

Incomplete dominance occurs when the heterozygous genotype for a trait is expressed as a blend. An example is blue feather color in chickens, in which a black allele and white allele together are expressed as blue feather color.
