Answer:
4. a
5. a
6. a
7. a
8. a
9. a
10. True
Explanation:
4. Units of inheritance in living organisms are known as genes. These genes exist in pairs in all organisms and a copy of each gene is passed down to the offspring during reproduction.
Correct option: a
5. Assuming the dominance of allele A over allele a:
AA x aa
Aa Aa Aa Aa
All the offspring will appear tall since the effects of allele a is masked by allele A.
Correct option: a
6. From the cross in (5) above, the genotypic ratio of the offspring is 100% Aa.
Correct option: a
7. Alternate forms of genes in living organisms are known as alleles. A copy of the alleles is usually passed down to the offspring during the process of reproduction.
Correct option: a
8. Phenotypes are the physical appearance of organisms. They are physical interpretation of genes.
Correct option: a
9. The law of segregation was postulated by Gregor Mendel. It states that gene pairs segregate during the process of meiosis and then randomly unite during the process of fertilization.
Correct option: a
10 Heterozygous organisms have two different alleles for the same genes. For genes that obey Mendelian laws, heterozygous condition is characterized by one dominant and one recessive alleles.
Answer:
1. Stratus
2. Cirrus
3. Cumulus
4. Both Cumulus and Cirrus
Explanation:
Answer: Option C) Determining the link between genes and the traits they influence.
Explanation:
First, the field of molecular biology seeks to understand the relationship between genes and proteins. Now, since genes are specific sequences on the DNA that codes for functional proteins, and these proteins make up the various traits physically expressed in living organisms such as skin color, blood group etc.
Then, the specific research goal of Carlita would be determining how genes control the expression of individual traits at the molecular level
