Given the following cross TtYyRr x TtyyRr (T = tall; t = short Y = yellow; y = green R = round; r = wrinkled), what proportion o

mihalych1998 [28]

Answer:

3/32 ttyyR-

Explanation:

Cross: Tall, Yellow, Rounded individuals with a tall, green, rounded individual

Parentals) TtYyRr x TtyyRr

Gametes) TYR, TyR, TYr, Tyr, tYR, tyR, tYr, tyr (Parent one)

TyR, TyR, Tyr, Tyr, tyR, tyR, tyr, tyr (Parent two)

We need to know what proportion of offspring is expected to be short plants with round, green seeds. So we need to identify the gametes for these traits. The genotypes are:

Shot → tt
Round → RR or Rr
Green → yy

⇒ Parent one can provide gametes tyR and tyr

⇒ Parent two can provide gametes tyR and tyr

(1/8 tyR x 2/8 tyR) + (1/8 tyR x 2/8 tyr) + (1/8 tyr x 2/8 tyR) =

2/64 ttyyRR + 2/64 ttyyRr + 2/64 ttyyRr =

1/32 ttyyRR + 2/32 ttyyRr =

3/32 ttyyR-

A client is admitted to the hospital with severe renal colic caused by a ureteral calculus. later that evening the client's urin

Serjik [45]

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.

Most doctors and midwives recommend waiting at least ________ after birth to have intercourse.

Likurg_2 [28]

Darina [25.2K]

It is not possible for Sarah and Thomas to develop cystic fibrosis but it would be possible for one of their children to inherit it. Both Sarah and Thomas are heterozygous and in a heterozygous pair of alleles the dominant allele is the one that will present. Because Sarah and Thomas both have the heterozygous allele combination Ff they are carriers which means that they will not experience symptoms of cystic fibrosis but they could pass cystic fibrosis onto one of their children.
