In rats, the allele for long whiskers is dominant to the allele for short whiskers. At another gene locus, a dominant allele pro

duces whiskers and the recessive allele produces a rat with no whiskers. The alleles at these 2 gene loci assort independently. If a rat that is homozygous for both recessive alleles is crossed with a rat that is heterozygous at both gene loci, what percentage of the offspring are expected to have short whiskers? ( Enter the number only without the percent sign. For example, enter 100% as 100 and enter 12.5% as 12.5 )

Answer:

25%

Explanation:

We have 2 independent genes with 2 alleles each: L/l and W/w

  • W_: whiskers
  • ww: no whiskers
  • L_: long whiskers
  • ll: short wiskers

Individuals with short whiskers will have the genotype <em>WWll </em>or <em>Wwll</em>.

<u>A cross between a rat heterozygous for both genes and a homozygous recessive rat is done:</u>

<h3>WwLl x wwll</h3>

-The homozygous rat will produce only <em>wl </em>gametes.

-The heterozygous rat will produce the following gametes: <em>WL</em>, <em>Wl</em>, <em>wL</em>, <em>wl</em>.

If you do a Punnett Square, you'll get that 25% of the offspring will be WwLl and will have short whiskers.

iren2701 [21]

In assessing for complications in a client who has been using crutches for two weeks, the finding that is most important is the hand and wrist weakness which is number three because this is the part of the body that exerts the most effort because it supports the crutches in order for the body to move. And if it is weak, it could be a problem to the client using crutches.
