Answer:

The correct answer would be C) 75% large-toothed and 25% small-toothed.

It can be explained with the help of the law of dominance which states that the dominant allele expresses itself completely over the recessive allele in the heterozygous condition.

So, the genotype TT, as well as Tt, will result in the production of dominant trait or character in the offspring.

Thus, three (1 TT and 2 Tt) out of four offspring would have large teeth and only one offspring (tt) would have small teeth.

Hence, we can conclude that 75% of the offspring will have large teeth and only 25% will have small teeth.

The plant below is purebred for height tall. Write the alleles of this plant. In any cross for height, what kind of Offspring wi

Tomtit [17]

Answer:

All tall

Explanation:

If an organism is purebred, that means it is homozygous. That means, it contains two copies of the same allele (trait) at this particular gene. Lets denote the tall allele as T. That means the plant is TT, and purebred tall.

No matter what genotype (i.e. what 2 alleles) another plant has, the offspring will always be tall. That is because it will always inherit one T from the TT parent. Even if we cross it to a tt plant, all the offspring would be Tt. They would be heterozygous, but they would be tall.
