Answer:
Let's consider that red fruit is dominant over the yellow fruit.
<em>The phenotype of the red fruit of P1 will be red fruit and the genotype will be RR.</em>
<em>The phenotype of the yellow fruit of P1 will be yellow fruit and the genotype will be rr.</em>
To check the outcomes of the F1 generation, lets cross the P1 generation:
r r
R Rr Rr
R Rr Rr
<em>The results show that all the offsprings from the F1 generation will show the dominant phenotype which is red fruit and they will have Rr genotype. </em>

Explanation:
Myth: Is a bigger penis better?
Truth: Penises come in all shapes and sizes. The idea that bigger is better is simply false. What really makes sex better is compatibility with your partner and open communication about what feels good and what doesn’t.
Myth: Vaginas are tight or loose depending on the amount of sex a person has had.
Truth: The “tight vs. loose” idea is fairly common, but it is purely false. The vagina is a muscle that expands and contracts. When a person is aroused, the walls of the vagina soften and lengthen, making insertion easier. If they are nervous, the walls of the vagina will naturally contract, making insertion difficult.
Myth: Sex is painful.
Truth: Sex should feel good –even if you are having sex for the first time or if you have had sex before . Feeling safe and comfortable is what’s important. If someone is nervous or tense, their muscles will contract, which may cause discomfort. If something does not feel good, tell your partner. You may need to slow down, use a lubricant or stop until you are feeling ready and comfortable.
Myth: Everyone is having sex.
Truth: It may seem like everyone is having more sex than you. The fact is everyone has different sex drives. Some people want to have sex a lot, while others are not interested in sex at all. What’s important is you are true to yourself and not worrying about what other people are doing.

Answers: examples of host defence mechanism include: Innate anatomical and physiological barriers, Innate cellular and chemical defenses.
Explanation:
The capability of the human body to resist almost all types of organisms or toxins that tend to damage the tissues and organs is known as IMMUNITY. This host defence mechanism can be classified into INNATE or adaptive immunity.
The immunity that results from general processes, rather than from processes directed at specific disease organisms is called the INNATE IMMUNITY. The anatomical and physiological barriers of the innate immunity provides the first line of defence against pathogens. Examples of these barriers of the innate immunity includes:
--> Destruction of swallowed organisms by the low stomach pH and digestive enzymes
--> The vigorous mucociliary clearance mechanisms of the respiratory airways and lungs.
--> Resistance of the skin to invasion by organisms
While examples of innate cellular and chemical defenses include:
--> Phagocytosis of bacteria and other invaders by white blood cells and cells of the tissue macrophage System
--> lysozymes, a mucolytic polysaccharide that attacks bacteria and cause them to dissolute.
--> basic polypeptides which react and inactivate certain types of gram- positive bacteria
-->natural killer lymphocytes that can recognize and destroy foreign and tumor cells.
