Answer:

The blue allele is dominant to the yellow allele.

Explanation:

The blue allele is dominant to the yellow allele, because there is more of the blue allele than the yellow allele.

Answer:

The blue allele is dominant to the yellow allele.

Explanation:

This is a cross involving a single gene coding for flower colour in a particular plant. The flower colour gene possesses two alleles viz: blue allele (B) and yellow allele (b). A truebreeding plant is that which produces only one type of offspring and contains the same allele for a particular trait (colour in this case).

According to the question, a truebreeding blue flower (BB) is crossed with a truebreeding yellow flower (bb) to produce an all blue-flowered offspring in the F1 generation. This is because the blue allele (B) is dominant over the yellow allele (b) in that gene i.e. the blue allele will mask the phenotypic expression of the yellow allele in the heterozygous F1 offsprings (Bb) that were produced.

In his law of dominance, Mendel called the allele that masks the expression of another like the blue allele in this question, DOMINANT allele while the allele that is phenotypically masked or covered up like the yellow allele in this case, RECESSIVE allele.

Which of the following statements is true about the role of oxygen in cellular respiration?
ozzi
It is one of the beginning compounds.

This is the answer for many reasons. First off, it is not one of the ending compounds. It is only the end compound for photosynthesis. Second, it does not react to water as that is yet again photosynthesis. It does not react with carbon dioxide as carbon dioxide is what initially creates oxygen within cellular respiration.

Hope this helps!

3. What body movements are due to muscles working in opposed<br> groups? Explain
NikAS [45]

Answer:

Elbow

Explanation:

Muscle works in pairs and groups e.g biceps flexes the elbow and triceps extend it and it is called antagonistic muscle action.

The working muscle is called the primer mover or agonist. The relaxing muscle by another muscle is called synergists.

When muscles cause a limb to move through the joint range of motion,it could be synergists or antagonists.

I hope this will help you
