5. Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. In a

ddition, suppose that a dominant allele (L) codes for long eyelashes and a recessive allele (l) codes for short eyelashes. If two individuals heterozygous for both traits (tail color and eyelash length) mate, what's the probability of the phenotypic combinations of the offspring?
A. 1:1 ratio (half are polka-dot tails and short eyelashes; half are solid tails and long eyelashes)
B. 1:1 ratio (half are polka-dot tails and long eyelashes; half are solid tails and short eyelashes)
C. 9:3:3:1 ratio (9 polka-dot tails and long eyelashes, 3 polka-dot tails and short eyelashes, 3 solid tails and long eyelashes, 1 solid tail and short eyelash)
D. 9:3:3:1 ratio (9 polka-dot tails and short eyelashes, 3 polka-dot tails and long eyelashes, 3 solid tails and short eyelashes, 1 solid tail and long eyelash)

Answer:

C.

Explanation:

According to your problem, you have to two traits to be crossed, tail and eyelashes:

P - polka-dot tail                L - long eyelashes

p - solid colored tail           l - short eyelashes

It says we cross two individuals that are HETEROzygous for both traits, this means that their genotypes have each allele for each trait. So the cross would be:

PpLl x PpLl

Attached is a Punnet for this cross and ratio count for both genotype and phenotype.

The ratio based on phenotype would be the following:

9 polka-long: 3 polka-short: 3 solid-long: 1 solid-short

What might it mean if a pulse were normal (grade 2/4) on the right limb, and absent (grade 0/4) on the left?
Aloiza [94]
Grant on 0/4 on the left means that there is no pulse on the left.

This could indicate blood clot that hinder the blood flow in your veins. You need to go to the doctor immediately because you're exposed to a high risk of a heart attack.

How respiration and photosynthesis are important to one another?
erik [133]

Answer: without photosynthesis, there would not be any glucose or oxygen and those are what start off the respiration reaction. without respiration plants would use up all CO2 and starve to death. photosynthesis requires the products from respiration and vise-versa.
