What are Genes that produce alternative expressions of a trait called

Biology
1 answer:
Brrunno [24]3 years ago
3 0
The answer should be allele(s).

Alleles are alternative forms of genes. For example in eye color, there is brown eye allele that produces brown eyes or blue eye alleles that produces blue eyes. 

However, note that there may be dominant or recessive alleles. Dominant alleles are always expressed, meanwhile, recessive allele is only expressed when there is no dominant allele existing. 

An example is let say brown eye allele is dominant and blue eye allele is recessive. The eye gene is controlled by 2 alleles. If I had one brown eye allele and 1 blue, my eyes will be brown, because brown eye allele is dominant.

Which statement about the starch debranching enzyme is correct?
Roman55 [17]

Answer:

B) If two non functional copies are inherited, the pea will be wrinkeld.

Explanation:

The gene for starch debranching is one of the genes that regulate more than one genetic trait. The starch debranching gene also regulates the seed shape in peas. The gene has two alleles. The allele B is completely dominant over allele "b" with respect to seed shape. Both homozygous and heterozygous dominant genotypes (BB and Bb) produce smooth seeds while homozygous recessive genotype (bb) imparts wrinkled shape to the seeds.

Only red algae can grow in relatively deep regions of the ocean because red algae are: Select one: a. capable of absorbing carbo
Effectus [21]

Answer:

b. specialized for absorbing shorter wavelengths of light that penetrate deeper into the water for photosynthesis.

Explanation:

There are two lights which are responsible for the photosynthesis in plants and algae i. e. red and blue light. These two lights are absorbed by the plants and algae in the process of photosynthesis while most of the light colors are reflected. In water red light remains in low depth while blue light penetrate deep into the water due to its shorter wavelength. So that's why red algae can grow due to the presence of blue light and photosynthesis occurs.

In humans, dimples (D) are dominant over no dimples (d). Curly hair (A) is dominant over
jeyben [28]

Answer:

1. ddaa

2. DdAa

3. One from each parent

4. False

5. 0.25

6. 0.25

7. 0.25

8. 0.5

Explanation:

The remaining part of the question is  

1. What is Jane's genotype?  

2. What is Paul’s genotype?  

3. Where did Jane get her gene for curly hair? From her mother or father?  

4. True or False: Jane's mother was heterozygous for curly hair?

5. What fraction of Paul and Jane's children should have curly hair and dimples?  

6. What fraction of their children would have straight hair and no dimples?  

7. What fraction should have dimples but not curly hair?  

8. What is the probability of getting any offspring with dimples

Solution

1. Genotype of Jane's mother -ddaa

2. Genotype of Paul (heterozygous for dimples and curly hair) – DdAa

3. One “a” gene from mother (whose genotype for hair was aa) and second “a”gene from father (whose genotype was  Aa)

4. False.  She was having straight hair

5. Offspring of  Paul and Jane  

DdAa (4), Ddaa (4), ddAa(4) and ddaa (4)

4 out of 16 offspring will have curly hair and dimples = 0.25

6. ddaa, 4/16 = 0.25

7. Ddaa , 4/16 = 0.25

8. Ddaa, DdAa, 8/16 = 0.5
