If we talk about guinea pigs, the trait of hair length is controlled by a gene with two alleles.
Allele for short hair (S) is dominant on the allele for the long hair (s).
The texture of hair texture is controlled by a gene with two alleles. It can be rough or smooth, and the allele for rough hair (R) is dominant on allele for smooth hair (r).
Now coming towards the question:
- A female guinea pig is heterozygous for hair texture and homozygous recessive for hair length.
Phenotype of the female will be Rough and long hair.
- A male guinea pig is homozygous dominant for hair texture and hair length.
Phenotype of the male will be Rough and short hair.
Hope it help!
Answer:
<h2>Dense connective tissue.</h2>
Explanation:
This is a type of connective tissue that has fibers, which are composed of collagen. You can refer to the image attached to see the parallel bundles of these collagenic fibers.
So, basically this formations help to forms strong tissue like tendons or ligaments.
The correct terms to fill in the blanks are gastric cavity and extracellular. In cnidarians, the mouth of both the medusa and polyp form opens into an internal gastric cavity where extracellular digestion takes place. The polyp and medusa are body forms that can be found in the phylum Cnidaria. The polyp is a nonmotile body form while the medusa is a free swimming body form.
