Codominance is a form of inheritance in which two different alleles for a gene are both expressed, and neither allele is dominan

t over the other. One example of codominance is blood type in humans; the alleles for type A blood and type B blood are codominant. If a man who is homozygous for type A blood and a woman who is homozygous for type B blood have children, what would you expect to find in the children?
Half will have type A and half will have type B blood.
The children will all have type B blood.
The children will all half type A blood.
The children will all have type AB blood.

First we establish a table of genotypes and phenotypes:

genotype  phenotype
AA             type A
BB             type B
AB             type AB

Homozygous type A   has genotype AA
Homozygous type B   has genotype BB

Now we make the punnett square

           A             A
B        AB          AB
B        AB          AB

So we see that all (100%) of outcomes are type AB.

Based on the anatomical and physiological differences between an infant and an​ adult, which finding would suggest respiratory d
frosja888 [35]

Answer: Excessive movements of the walls of the  abdomen

Basically babies belly breathe, that is they undergo abdominal pattern of respiration( instead of the abdomino- thoracic pattern in  adult), through their abdomen.

<u>This is because,  their thoracic walls are not fully functional to undergo  the normal adult mechanisms  of breathing</u>.

<u>The ribs are short in length due to incomplete ossification. They curve out wards, at low angle, their sternum, is shaped horizontally.</u>

These features reduce the activities   of the inter coastal muscles and the thoracic cage  in the mechanism of  infants breathing,compare to the long ribs, obliquely shaped rib cage,  with lower  sternum  of  adult which  permit the  abdominal-thoracic  breathing pattern.

Therefore ,when the diaphragm distends during breathing ,its movement pushes the organs of the abdomen down; because infants have rapid respiratory  rates, the distends created  rapid  expansion and contraction of the walls of the abdomen to gain enough abdominal pressure.

This together with the movement of  organs of the abdomen   from  the  pathways of diaphragm  created the  excessive  movements of the abdominal walls. This rapid abdominal wall movements creates discomfort and distress for the infant during this mechanisms.

The calcium present in the milk acts as a fertilizer, for the growth of pumpkin size.

Explanation:

Scientific answer: Milk contains nutrients, minerals mainly calcium which are good for the growth of the plant as a fertilizer.

Milk gets readily absorbed by the roots due to the solubility of nutrients in milk.

The root hairs of the plant transport the calcium to the other parts like stem.

This will only help when all other factors of plant growth are present as sunlight, water other than fertilizer.

Non-scientific question:

The Hypothesis here is those pumpkin plant fed with milk are bigger on size.

Also injecting stems with milk would cause no good.

Pumpkin plants fed with milk and some plants fed with water are compared, we get the result that giant pumpkins are one that are fed with milk. This is  statistical analysis.
