Answer:
The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring
Explanation:
Crossing over is a method of variation
Answer:
Food borne intoxication
Explanation:
Foodborne diseases occur when we consume food which is contaminated with a pathogenic microbe or toxins released by these microbes. Foodborne diseases can be classified into foodborne infection and foodborne intoxication.
Foodborne infection occurs when we consume food contaminated with pathogenic organisms and foodborne intoxication occurs when we consume food which contains toxins or poisonous substances released by the pathogenic microbes.
Botulism is a foodborne intoxication caused by ingestion of toxins produced by C. botulinum. So the correct answer is foodborne intoxication.
Answer:
50% medium tail and 50% short tail.
Explanation:
Let the allele that controls the tail length in cat be represented by T.
Cats with short tail length will have the genotype of tt.
Cats with long tail length will have the genotype of TT.
Since the trait exhibit incomplete dominance, cats with medium tail length will have the genotype of Tt.
A short tail cat (tt) is crossed with a medium tail cat (Tt).
tt x Tt = Tt, tt, Tt, and tt
<em>Recall that phenotypically, Tt = medium tail and tt = short tail. Hence, 1/2 or 50% of the offspring will have medium tails while the remaining 1/2 or 50% will have short tails.</em>
Hence, the possibilities are 50% medium and 50% short tail cats.
A fossil record is evidence for evolution because you can compare the fossiles to see the difference. You can tell how "survival of the fittest" played a part, and what characteristics the species had to help them survive in their environment.
