Answer:
12!
Explanation:
Sex cells only carry half of what makes up the organism's DNA. This is so that when they find a mate, in this case- another tomato, their sex cells and their partner's sex cells will add up to the appropriate amount of chromosomes in the organism's DNA. In this case, 24.
It is intended to increase immunity against that antigen back to protective levels, after memory against that antigen has declined through time.
Answer:
Endocrine and Cardiovascular system
Explanation:
Excess fat intake leads to different health hazards. They affect the body and cause lipids to clog the arteries thereby preventing blood from quickly delivering oxygen to the body parts.
Excess fat intake causes fatty pancreas and decreases its function.
It also causes series of cardiovascular diseases such as heart attack; elevated cholesterol/atherosclerosis,abnormal heart rhythms, hypertension, stroke etc
Explanation:
<h3><u>If the genes were linked:</u></h3>
<u>Parental cross: EW/EW X ew/ew</u>
F1 genotype: EW/ew
F1 Gametes:
- Parentals (more abundant): EW and ew
- Recombinant (less abundant): Ew and eW
<u>Test cross: EW/ew X ew/ew</u>
<u>F2 genotypes:</u>
- Parentals: EW/ew; ew/ew;
- Recombinant: Ew/ew; eW/ew
<h3><u>If the genes are not linked:</u></h3>
<u>Parental cross: EEWW X eeww</u>
F1 genotype: EeWw
F1 gametes: EW, Ew, eW, ew. Genes assort independently, so all of the possible gametes of the F1 individual will have the same probability.
<u>Test cross: EeWw X eeww</u>
<u>F2 genotypes:</u>
- 1/4 EeWw, 1/4 Eeww, 1/4 eeWw, 1/4 eeww
