Answer:

“Clearly, some testing and research is done in dogs for historical reasons [existence of benchmark data] rather than because they are the best models

Explanation:

It is unconscionable that dogs, the most popular companion animals in the country, are used as research subjects in laboratories, but that is the tragic truth. United States Department of Agriculture (USDA) reports show that tens of thousands of dogs are used in research, testing, teaching, or experimentation in the U.S. every year by research facilities, including hospitals, schools, diagnostic laboratories and private firms in the pharmaceutical and biotechnology industries.

Although the number of dogs used in research has declined by 72% since their peak use in 1979, the most current USDA statistics show that 59,401 dogs were used for “research, testing, teaching, or experimentation” in 2018, although the exact purposes for which these dogs were used remain unclear.

Answer:

The correct answers are option a. The greater the undifferentiated cell count, the more aggressive the cancer and b. Malignant tumors have the potential to kill the host.

Explanation:

Anaplasia is a medical term used to describe a condition of cells with poor cellular differentiation. It is known that the great the anaplasia, the more aggresive is the cancer. The tumors that have this characteristic are known as anaplastic carcinoma. This malignant tumors have the potential to kill the host  when they metastasize to other organs.

Andre45 [30]

Behavioural genetics is the study of the effects of genes as well as well the environment on the behaviour of the individuals. The scientists who study the Behavioural genetics are known as behavioural geneticists.

In this case Dr. Hakim is studying the influence of genes and the environment on the aggression, which is a kind of behaviour. Hence, Dr. Hakim is a  behavioural geneticists, and he works in in the field of behavioural genetics.

if there are 100 individuals in a population and 20 are homozygous for b, 60 are heterozygous, and 20 are homozygous for b, what
Yuri [45]

If there are 100 individuals in a population and 20 are homozygous for b, 60 are heterozygous, and 20 are homozygous for b, the allele frequency of b is 50%.  

Allele frequency, sometimes referred to as gene frequency, is the percentage or fractional frequency of an allele (gene variant) at a certain location in a population. What is being discussed is the proportion of chromosomes in the population that carry that allele in comparison to the entire population or sample size. The slow change in allele frequencies within a population is known as microevolution.

Taking into consideration:

1. A particular allele at a particular chromosomal region.

2. A collection of N individuals with ploidy n, which denotes that each individual's somatic cells have n copies of each chromosome (e.g. two chromosomes in the cells of diploid species).

If an allele is found in a population on I chromosomes, the allele frequency is the proportion of all I occurrences of that allele to the total number of copies of the chromosome in the population (nN). Despite being related, the genotype frequency and the allele frequency are separate and one can infer the other from the other.
