Answer:
3/16
Explanation:
<u>According to Mendel's law of independent assortment of genes, when a dihybrid cross involves two genes that assort independently and one of the parents is dominant for the two genes and the other is recessive, the phenotypic ratio of the offspring at F2 would be 9:3:3:1</u>. The proportion of the offspring with the dominant parental traits would be 9/16, those with the recessive parental traits would be 1/16, while those with mixed traits would be 3/16 each.
Assuming the eye color is represented by E and the wing shape is represented by W. At F2
EeWw x EeWw
E_W_ - 9/16 (dominant for both eye color and wing shape)
E_ww - 3/16 (dominant for eye color and recessive for wing shape)
eeW_ - 3/16 (recessive for eye color and dominant for wing shape)
eeww - 1/16 (recessive for both eye color and wing shape)
<em>Hence, the proportion of the offspring with dominant phenotype for eye color and recessive phenotype for wing shape would be </em><em>3/16.</em>
It becomes more alkaline where pH will be more than 8
The answer is a. because bacteria are prokaryotes and therefore don't have mitochondria

The correct answer is explained below:</h2>
Explanation:
- According to the question, free ear lobes are dominant over attached ear lobes.
- Let the allele for free ear lobes be represented by F.
- Let the allele for attached ear lobes be represented by f.
- The genotype of the homozygous recessive woman (mother) having attached ear lobes is : ff.
- The gamete produced by the woman is: f.
- The genotype of the heterozygous man (father) with free earlobes is: Ff.
- The gametes produced by the man are: F and f.
- Mating the man with the woman we get the following offspring,
F f
f Ff ff
Phenotype Free ear lobe Attached ear lobe
- The genotype and the phenotype of the probable children obtained is represented in the Punnett square above.
- The probability that the parents would produce children with attached ear lobes is =
.
I think the answer is chemosynthesis because deep ocean vents don't get sunlight.
