a cross between a homzygous tall plant and homzygous short plant would predict that the offspring had: A the same genotype as on
11Alexandr11 [23.1K]

Answer:

C

Explanation:

The correct answer would be <u>a genotype that was different from that of both parents.</u>

Let us assume that the allele for height is A (for tall) and a (for short). Homzygous tall plant would have the genotype AA while homzygous short plant would have the genotype aa. Crossing both genotypes:

                AA   x   aa

             Aa   Aa   Aa   Aa

<em>All of the offspring, even though have the same phenotype as one of the parents, have unique genotype from either of the parents. While the parents are AA/aa, the offspring are Aa.</em>

The correct option is, therefore, C.

DNA has unique properties that allow it to accurately retain genetic information, even after multiple rounds of replication. One
Bingel [31]

Answer:

G= 22%

A=28%

T= 28%

Explanation:

Given that percentage of cytosine content (C) = 22%

Since C pairs with G, percentage of guanine content (G) would also be = 22%

Hence, G+C = 22+22 = 44%

This means that A+T = 100-44= 56%

Since adenine pairs with thymine so, percentage of A= percentage of T

Hence percentage of Adenine (A)= 56/2 = 28%

And percentage of Thymine (T) = 28%
