A man with hemophilia (a sex-linked recessive condition) has a daughter without hemophilia, the probability of their children having hemophilia is 50%, out of 4 children probably 2 will have hemophilia and 2 will not have hemophilia.
<h3>What is recessive and dominant?</h3>
The dominant term is related to the genetic transmission of a trait and is represented, in biology, by a capital letter (A, B or V). While recessive, represented by a lowercase letter (a, b or v), they represent genetic traits transmitted only in the absence of the dominant gene.
With this information, we can conclude that Recessive genes produce proteins considered “defective” as they become inactive. That is, they are hidden (recessive) with the presence of a dominant gene manifesting their characteristics in the absence of their dominant allele.

The natural barriers include biochemical, physical, and mechanical, as well as inflammation of the body.
Natural barriers and the immune system defend the body against the species that leads to infection. The natural barriers include the mucous membranes, skin, earwax, tears, stomach acid, and mucus. Also, the usual flow of urine washes out the microbes, which enter the urinary tract.
Answer:
hydroponic greenhouse.
Explanation:
Hydroponic greenhouse is a type of greenhouse that would be best in Siberia where the growing season is short and we wants fresh tomatoes all year round. Tomato plants are able to grow takes less time in hydroponic greenhouse because plants grow 30% to 50% faster in hydroponics than when grown in soil. Under the right conditions, the productivity of tomato is higher three and 10 times as compared to traditional methods of tomato cultivation.
