Answer:
Co-Dominance
Explanation:
Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.
Example:
A brown cow and a white cow have a baby. The baby cow is white with brown spots. The baby cow is a result of co-dominant offspring.
Answer:
The correct answer is - option A. mandible.
Explanation:
Mandible is the bone of jaw especially lower jaw. It is not a bone that protects any vital organ it just help to close and open mouth for essential mouth movements like eating and talking.
Sternum and Ribs are the bones that plays role in providing protection to vital organs such as heart and lungs. Vertebral column is the bone that protects spinal chord while providing stiffness to the body and back.
Thus, the correct answer is option A. mandible.
According to the Punnett square for this cross, 50% of offspring is predicted to have blue feathers. This is because the trait of a blue feather is dominant over the trait of a white feather. Thus, the correct option is B.
<h3>What is Punnett Square?</h3>
Punnett square may be defined as a kind of table in which all of the probable products for a genetic cross between two individuals with known genotypes are presented in a precise manner.
The complete question is described in the image given below:
When a Parakeet that is heterozygous (Bb) for blue feather (dominant) is crossed with a Parakeet that is purebred (bb) for white feather (recessive), the genotypes of the resultant offspring are Bb, bb, Bb, and bb.
In which 50% of the offspring possess blue feathers (Bb) while 50% of the offspring possess white feathers (bb).
Therefore, the correct for this question is B.
