In a plant species, you notice that purple and yellow leaf colors, as well as hairy and smooth stems segregate independently. Yo
Reptile [31]

Answer:

The required answer is given below:

Explanation:

a) Assuming C is the gene for leaf color and S is the gene for the stem type.

then, the genotypes for each parent would be-

Yellow leaves, hairy stem parent: ccSs

Purple leaves, hairy stem parent: CcSs

b) Expected ratios of the progeny as below:

68 yellow leaves, hairy stems: 3/8

66 purple leaves, hairy stems: 3/8

22 purple leaves, smooth stems: 1/8

25 yellow leaves, smooth stems: 1/8

Hence, the ratio is - 3:3:1:1

It might possible that  independently assorting single gene pairs could control traits, and that one of the alleles in each pair is dominant.

c) The general formula for calculating X2:

X2 =  the sum of (O - E)2/E,

(where O = observed number)

(E = expected number)

So,

(68 – 68)2 /68 + (66 – 68)2/68 + (22 – 23)2 /23 + (25 – 23)2/23

= 0.276

X2 = 0.276

The chi-square statistic too small, Hence the hypothesis is acceptable.

Investigators examined the expression of transporter mrna and protein produced in zebrafish homozygous for each of the alleles a
svlad2 [7]
The allele which has light color appears to be altering transcription and that is why the corresponding mRNA is absent in zebrafish which is homozygous. The protein we can say were absent because mRNA which is being required for protein synthesis it was not present. 
If the allele had altered translation, mRNA which is functional would have been present but in the same case, the protein will still be absent.
