Answer:
The correct answer would be -
1- YR, Yr, yR and yr.
2. Yr, yR
3. YR, yr
4. YR, Yr, yR & yr
Explanation:
A mature male or female haploid germ cell that fuses with another gamete of the opposite sex during the process of fertilization to make a zygote in sexual reproduction.
The law of Independent Assortment presented by Mendel says that alleles for different traits are passed and assort independently of one another in the gametes.
1. If Y and R on different chromosomes then they will produce four gametes and assort independently - YR, Yr, yR & yr.
2) If Y and R on the same chromosomes and no crossing over occurs then they will produce only two gametes as Y and R will not come together - Yr & yR.
3). if dominant Y and recessive r are on the same chromosome, no crossing over then only two gametes will form as Y and r will not assort together - YR & yr.
4). if dominant Y and R are on the same chromosome, 50% crossing over produces 4 types of gametes, YR, Yr, yR & yr.
<span>Palpation and percussion can cause an increase in normal bowel sounds and hide abdominal vascular sounds. Therefore it is wise to perform auscultation prior to percussion and palpation during clinical assessment of the renal system. Palpation should be avoided if a client is suspected of having a tumor because it could harm the client. It is more important as part of clinical assessment of the renal system to listen for bruit by auscultating over the renal artery. Bruit indicates renal artery stenosis. The nontender areas should be examined prior to tender areas to avoid confusion regarding radiating pain from the tender area being percussed.</span>
