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
needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.

can you put a picture of the pungent square please
Answer:
1. Immobilisation is to make immobile or immovable; fix in place. to prevent the use, activity, or movement of: The hurricane immobilized the airlines. to deprive of the capacity for mobilization: The troops were immobilized by the enemy.
2.An immobilized enzyme is, therefore, attached to an inert, organic, or inorganic or insoluble material, such as calcium alginate or silica. Furthermore, the attachment of an enzyme to a solid support can increase its resistance to various environmental changes such as pH or temperature
