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 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
