he correct answer is number one. A chromosome is composed of many genes. A chromosome is referred to as a DNA molecule in an organism's body, which consists of genetic materials. Chromosomes consists of numerous genes within them, in their nucleus and mitochondria, genes are found inside the Chromosomes itself
Answer:
Explanation:
If im correct, the pea plant study was a way to use plants with their different traits to study Dominant and Recessive traits in plants.
He crossed a smoother pea with a more wrinky one and used the offspring as a way to determine dominant and recessive phenotypes.
I may be incorrect but I hope this helps!
The answer is 'Genes and Chromosomes'...
ive recently taken a quiz w/ this question on it!
Answer:
It is possible to compare the expression of homologous genes in the brain of <em>D. melanoganster</em> and humans, because the expression levels of conserved genes may be associated with the evolution of cognitive features such as complex learning and memory.
Explanation:
Model organisms can be used to understand the patterns and processes that affect human evolution. <em>Drosophila melanogaster </em>is a model organism that has been used to study expression patterns of conserved genes in the course of evolution. This model organism has also been used to develop genetic mutant lines in order to examine the role of genes evolutionarily conserved in animals, including those involved in neurocognitive development.
In genetic research, an experiment as the above described is framed in a research field named 'Behavioral Genetics', which is a discipline that studies how evolutionarily conserved gene networks may be associated with neurocognitive tasks during brain evolution.
