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>
All of the above are true.
A is correct, because, well. We can’t see atoms directly, at least not with our current levels of technology.
B is correct because a model is a representation of something by nature.
C is correct because our knowledge of the atom is still growing, and as we still don’t know about some future atomic developments, it’s called a model so that there’s still flexible room for new discoveries.
Hope this helps!
Cerebellum is part that helps us keep from falling.
Solution:
Chromosome contains hundreds to thousands of genes.
Every human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes.
A trait is any gene-determined characteristic and is often determined by more than one gene.
Some traits are caused by abnormal genes that are inherited or that are the result of a new mutation.
Proteins are probably the most important class of material in the body. Proteins are not just building blocks for muscles, connective tissues, skin, and other structures. They also are needed to make enzymes. Enzymes are complex proteins that control and carry out nearly all chemical processes and reactions within the body. The body produces thousands of different enzymes. Thus, the entire structure and function of the body is governed by the types and amounts of proteins the body synthesizes. Protein synthesis is controlled by genes, which are contained on chromosomes.
Deoxyribonucleic acid (DNA), which contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.
