Answer:
a) 1/2 red, 1/2 pink; b) all pink; c) 1/4 red, 1/2 pink, 1/4 white; d) 1/2 white, 1/2 pink
Explanation:
The flower color trait in snapdragons shows incomplete dominance: the heterozygous genotype produces an intermediate phenotype between the two different homozygous genoytpes.
<u>The possible genotypes and phenotypes are:</u>
- R1R1 : red
- R1R2: pink
- R2R2: white
<h3>a. R1R1 X R1R2
</h3>
The R1R1 individual only produces R1 gametes. The R1R2 parent produces 1/2 R1 gametes and 1/2 R2 gametes.
<u>For that reason, the F1 will be:</u>
- 1/2 R1R1 (red)
- 1/2 R1R2 (pink)
<h3>b. R1R1 X R2R2
</h3>
The R1R1 individual only produces R1 gametes. The R2R2 parent only produces R2 gametes.
<u>For that reason, the F1 will be</u> :
<h3>c. R1R2 X R1R2
</h3>
Both parents are heterozygous. This is a monohybrid cross, and from Mendel's Laws <u>we expect the following offspring:</u>
- 1/4 R1R1 (red)
- 2/4 R1R2 (pink)
- 1/4 R2R2 (white)
<h3 /><h3>d. R1R2 X R2R2</h3>
The R1R2 parent produces 1/2 R1 gametes and 1/2 R2 gametes. The R2R2 individual only produces R2 gametes.
<u>For that reason, the F1 will be:</u>
- 1/2 R2R2 (white)
- 1/2 R1R2 (pink)
Answer:
for the first it could effect how much the baby weighs or how healthy they are depending on what you eat as for the second No they will not it is impossible because those happened before the baby was born so it is in NO way possible for the baby to inherit these traits

The question is incomplete as it does not have the options which are-
1. narcotic analgesics
2. non-narcotic analgesics
3. anti-psychotic barbiturates
Answer:
Non-narcotic analgesics
Explanation:
Non-narcotic analgesics are the drugs used medication to treat and control the inflammation and pain. They are used to treat mild to moderate pain usually but with other medications to treat severe pain like Advil, Tylenol and other.
The drug act by preventing the perception of the pain stimulus by blocking the transmission of the impulses generated in response to pain to the central nervous system.
Thus, Non-narcotic analgesics is the correct answer.
Question is a multiple choice question.
Answer:
Question 1. The major advantage of using artificial chromosomes such as YACs and BACs for cloning genes is that:
Answer:
(C)
Explanation:
YACs and BACs can carry much larger DNA fragments than ordinary plasmids can.
Question 2. Simply inserting an entire eukaryotic gene into a prokaryotic expression system will most likely not work for the following reason.
Answer:
(B)
Explanation:
Prokaryotes lack introns
