Infer How do dominant and recessive<br> factors interact? sc.7..16.1
Rama09 [41]

Answer:

The resulting characteristic is due to both alleles being expressed equally. An example of this is the blood group AB which is the result of codominance of the A and B dominant alleles. Recessive alleles only show their effect if the individual has two copies of the allele (also known as being homozygous) If you were to talk about dominant and recessive factors in human traits, such as brown/green eyes, brown would be dominant, only needing to be in 1 parent to pass down to the child. (i have no idea if this helps or not-- it's all i know.. sorry, ;w;)

Hemophilia is an X-linked recessive disorder (Xh) that is passed through generations and can be traced by using a pedigree. What
Radda [10]
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>

According to the basic host–pathogen model, if the combined death and recovery rate from a disease doubles, and the effectivenes
S_A_V [24]

Answer:

A. decrease by half.

B. stay the same.

C. double.

Explanation:

Host-pathogen models resembels the host-parasite models and predator-prey which is used to evaluate the evolutionary strategies of pathogens.

The host-vector-pathogen system can be demonstarted as a change in the number of 4 types of people: healthy hosts, uninfected vectors, infected hosts, and infected vectors.

The threshold density should decrease by half, stay the same, or double, according to the standard host-pathogen model, if the combined death and recovery rate from a disease doubles, and the ability of the disease to spread from infected to uninfected persons.

Hence, the correct options are A. decrease by half, B. stay the same, and C. double.
