One difference is that DNA is a double strand and RNA is a single strand. Another difference is that sugar in a RNA molecule is ribose, and the sugar in the molecule in DNA is called deoxyribose. Hope this helps, good luck!

RNA is a single-stranded nucleic acid.

RNA has a ribose sugar instead of a deoxyribose sugar like DNA.

RNA nucleotides have a uracil base instead of thymine.

Short hair (L) is dominant over long hair (1) in rabbits. Two heterozygous rabbits are mated. Show the punnett square. What phen
Gekata [30.6K]

Answer:

When two heterozygous short haired rabbits are crossed, the short hair being dominant and the long hair recessive, the phenotypes in the offspring will be 75% short hair and 25% long hair, with a short hair:long hair ratio of 3:1.

Explanation:

The crossing of two hybrid individuals for a trait has the probability of producing <u>offspring that exhibit the dominant trait at 75% and the recessive trait at 25%, with the ratio of the dominant trait to the recessive trait being 3:1</u>.

Considering the hair length trait, in rabbits the short hair (L) is the dominant trait and the long hair (L) is recessive, two heterozygous hybrid individuals Ll are crossed:

<em><u>Genotype of the parents</u></em>:

  • ♂ Ll
  • ♀ Ll

Ll X Ll

<u>Punnett Square </u>

Alleles        L      l

L                 LL    Ll

l                  Ll      ll

Where the offspring have a genotype:

<em>Ll 50% </em>

<em>LL 25% </em>

<em>ll 25% </em>

With a ratio Ll:LL:ll of 3:1:1.

Phenotype:

<em>Short hair 75%. </em>

<em>Long hair 25%. </em>

Phenotypic ratio short hair: 3:1 long hair.

In the crossing of two heterozygous short-haired rabbits, taking into account the dominance of the short hair,  phenotypes in the offspring will be 75% short hair and 25% long hair, with a short hair:long hair ratio of 3:1

Zolol [24]

While most DNA replicates with fairly high fidelity, mistakes do happen, with polymerase enzymes sometimes inserting the wrong nucleotide or too many or too few nucleotides into a sequence.
