Two short-tailed Manx cats are bred together. They produce 3 kittens with long tails 5 short tails and 2 without tails. From the
Dmitry [639]

Answer and Explanation:

There are three phenotypes, so it seems that this an example of incomplete dominance, with the short tail being the intermediate form between long-tail and no-tail. Incomplete dominance is a condition where neither of the alleles completely dominates over the other one. Dominant alleles cannot completely cover up the recessive alleles. Descendents possess an intermediate phenotype between the two parental phenotypes and not the dominant one, which would appear if this would be the case of complete dominance.

<u>Available data:</u>

  • Two short-tailed Manx cats are bred together.
  • F1: 3 kittens with long tails, 5 short tails, and 2 without tails.

The T gene might express the tail trait. T allele expresses long the tail and is dominant over t allele which expresses the absence of the tail.  

So, homozygous dominant individuals, TT, are long-tailed animals

homozygous recessive individuals, tt, have no tail

Heterozygous individuals, Tt, are short-tailed animals, the intermediate form.

Cross: Two short-tailed Manx cats are bred together

Parental)  Tt    x    Tt

Gametes) T   t   T   t

Punnet Square)  T        t

                   T    TT     Tt

                    t     Tt       tt

F1)  1/4 TT = Long-tailed animals

     2/4=1/2 Tt = Short-tailed animals

     1/4 tt = untailed animals

The ratio 3:5:2 of the progeny in the example is close enough to the Mendelian ratio 1:2:1.

In the human body, muscle cells have an increased need for energy during exercise. To help supply this energy, the body will imm
matrenka [14]

The correct answer is option (h) the breathing rate to supply more oxygen to cells for the release of energy.

Breathing refers to the process of inhaling oxygen and exhaling carbon dioxide from the lungs. A normal breathing rate at rest is around 15 breathes per minute which is significantly increased to 40 -50 breathes per minute during vigorous activity or excercise.

During exercise, the breathing rate, pulse rate and lactic acid levels increase in the human body. Muscle cells have an increased need for energy and heart pumps more oxygen to the muscle cells to meet the requirement. Breathing rate increases to supply more oxygen to the muscle cells which is required for the oxidation of the glucose, release of more energy and to get rid of the carbon dioxide.

hoa [83]

A nucleic acid is made of nucleotides, and nitrogenous bases are a part of a nucleotide.


DNA is a nucleic acid.  The nucleotides in DNA are made up of a sugar (deoxyribose), a phosphate group, and one nitrogenous base (which will be either adenine, guanine, cytosine, or thymine).


Hope this helps!!
