1. What percentage of the offspring will be heterozygous?
2. Why does each parent contribute only one allele to the offspring?
Answers
Answer:
1. 50%
2. Every gamete only contains 50% of the genetic information or half of the information for a gene.
Explanation: 1. Heterozygous means the pairs consist of a dominant and a recessive, or one big and one small letter, so only 2/4 or 50% are heterozygous.
2. Every sex cell has half of the chromosomes you need to make an embryo so you end up only having one allele as well
Heterogeneous means different
Here they are 2Total 4Percentage:-.
2/4×100=50%#2
It's because they only produce 50% not 100%

Why do you have to determine the total magnification when observing a specimen under the compound microscope?
Answers
Answer:
To clearly see specimens under the microscope, and to be able to see two separate objects that are close together.
Explanation:
A microscope is a tool that makes an object look bigger so that the person who is looking at it can see it. It's important to use a microscope because cells are usually too small to see with the naked eye. In addition to magnification, microscopes also have resolution, which is the ability to see two objects that are close together as separate. A microscope needs both magnification and resolution to be able to clearly see specimens under the microscope. When the light microscope bends light at the specimen, it gives the viewer a clear picture of the specimen. A series of lenses do this.

a. Mutations
b. artificial selection
C. exponential growth
d. genetic bottlenecking
Answers
Answer:
Mutation is a source of genetic variation
Answer:
Mutations
Explanation:
Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.
. What is the width of Grandmother’s pelvis, measuring from the pelvic brim? How does her pelvis differ
from Grandfather’s?
Answers
The width of Grandmother’s pelvis, measuring from the pelvic brim is 2cm.
The grandmother has a wider pelvis than the grandfather.
The pelvic brim is found at the edge of the pelvic inlet and measures around
2cm. The pelvis in females are always wider than those found in males. This
is due to the adaptation of the female pelvis to child birth.
The pelvis being wider aids the passage of the foetus from the womb and
eases childbirth. This is the reason why the grandmother has a wider pelvis
than the grandfather.

Epidemiology studies health-related states and occurrences (not simply diseases) in specific communities.Therefore, option (A) is correct.
What is epidemiology?The study and analysis of the distribution, patterns, and determinants of health and disease conditions in a given population is what epidemiology is all about. It is one of the most important aspects of public health, and it influences both policy decisions and evidence-based treatment by determining the factors that put people at risk for disease and setting goals for preventative medical care.
Descriptive, analytical, and experimental methods are the three primary approaches utilized in epidemiology. Descriptive epidemiology is the method that is utilized the most to investigate the occurrence of disease, despite the fact that all three can be employed to do so.
Therefore, option (A) is correct.
