A duplication consists of a piece of DNA that is abnormally copied one or more times. This type of mutation may alter the function of the resulting protein. Frameshift mutation: This type of mutation occurs when the addition or loss of DNA bases changes a gene's reading frame.

Mrs. Smith has blood type A. Mr. Smith has blood type B. Their first child has blood type AB. Their second child has blood type O. Now is Mr. Smith justified? What are Mr. and Mrs. Smith’s genotypes for these two genes?
the only possibilities for the childrens genotypes are; A and AB, so the fact that the child has a blood type of O isn't possible
The genotypes of Mrs. Smith and Mr. Smith are AO and BO, respectively. Therefore, the blood group of the offspring will be A, B, AB, and O.
What is Genotype?Genotype is the genetic makeup of an organism. Genotype refers to the alleles which are present in an organism.
ABO blood group shows multiple allelism which means it has more than two alleles which are A, B, and O. A and B alleles show co-dominance and O allele is recessive allele.
As per the information, Mrs. Smith has blood type A (genotype of Mrs. Smith could be AA/AO), and Mr. Smith has a blood group B (genotype could be BB/BO).
The blood group of the first child produced is AB. So, the genotype of this child is AB only. And, the blood group of their second child is O which is recessive. So, the genotype of the child will be OO only (homozygous).
Therefore, the genotype of the parents Mrs. Smith and Mr. Smith for their children to have blood group AB and O must be AO and BO only.

Answer:
C. Sex cells
Explanation:
The process shown in the figures is Mitosis, which is the division of cells that end in 2 identical daughter cells. Sex cells, however, do not go through mitosis as their offspring are genetically different; they go through a process called meiosis. The other cells listed are all somatic and therefore go through mitosis, so C must be correct.

What valuable information was gained from Mendel's dihybrid crosses?
Select all that apply.
1. Not all traits are controlled by genes. In most plants, genes only determine traits that affect
flower color.
2. Statistical and probability methods can be used to determine how likely an offspring is to inherit
certain traits.
3. Genes are inherited differently in plants than they are in animals.
4. Inheritance of one trait does not affect inheritance of another.
Mendel's dihybrid cross proves that the inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.
What is a dihybrid cross?When two different traits are crossed together then it is called a dihybrid cross. These two different traits are regulated by two different genes.
In Mendel's dihybrid cross, he did cross between round yellow and wrinkled grees. There are two traits, color, and shape. In the F1 generation, all seeds were round yellow but they were heterozygous. Round shape and yellow color are dominant traits.
Then he self-pollinated F2 generation and found four types of seeds that were round yellow, round green, wrinkled yellow, and wrinkled green in the 9:3:3:1 ratio. The cross is attached in the image below.
Inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.

The flooding of fields in winter can affect aquifers without having long term impacts on the height of the water table. Which statements explain why this is possible?
Select the TWO correct answers.
A. In winter, using groundwater to flood fields causes the water table to drop because water is withdrawn from the aquifer.
B. In winter, removing water from the aquifer causes the water table to rise because water covers the areas where rice is grown.
In spring, changes in the level of the river cause the water table to rise because water flows from the river into the aquifer.
C. In spring, removing water from the aquifer causes the water table to drop because water flows from the aquifer to the river.
D. In summer, changes in the level of the river cause the water table to rise because water flows from the river to the aquifer.
The flooding of fields in winter has no long-term effect on the height of the water table because removing water from the underground water - the aquifer causes water to drop and summer melts water into the water table.
Aquifers, Water Tables, Summer, and WinterDuring winter, the flooding of the field traps water from going back into the aquifers and the use of water from them causes the water level to drop.
Due to the melting of snow in summer, the water levels are normalized. Therefore, the correct answers are C and D.

There are millions of organisms on Earth that scientists have classified into different levels of organization. Which of these characteristics would be most important to scientists when classifying organisms?
a)where the organism lives
b)how small the organism is
c)the genes of the organism
d)the shape of the organism
Answer:
I think no. b is the ans or maybe not
There are millions of organisms on Earth that scientists have classified into different levels of organization. The characteristics which would be most important to scientists when classifying the organisms will be the genes of the organism. Thus, the correct option is B.
What are the different levels of organization?Taxonomy is the study of classification of organisms. Scientists have used many different types of information to place the different organisms into specific groups. The groups are arranged in different levels. These levels were named as kingdom, phylum, class, order, family, genus, and species.
The organisms which were present on the Earth were classified on the basis of the environment where they live, how small is the size of the organism, and the shape of the organism found such as rod-shape, cocci, spirillum, etc.
Therefore, the correct option is B.
