Answer:
D). genetic drift
Explanation:
Genetic drift is the change in an allele frequency over a period of time. This event has to be random and a chance event.
For example: In a population of a flowering plant there are two types of flowers, blue and yellow. Due to a fire many yellow flowers are destroyed by chance. Now the resultant population will have more blue flowers and when they reproduce the population will eventually evolve to have more blue flowers. Effect of genetic variation is more pronounced in a small population since its easy to disturb the allele frequency.
Answer:
Probably an animal cell because the cells are more rounded.
Explanation:
True. laws are there because government doesn’t want something to happen, trying to predict what’ll solve it. :)
The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern of the genes along the anterior-posterior axis of the developing embryo.
<h3>What are homeotic genes?</h3>
- Homeotic genes are a group of body pattern forming genes which control the development along the anterior- posterior axis of the developing embryo.
- These encode transcription factors which control and specify the genes involved in body patterning. These provide identity to the segments during embryo formation.
- Genes located in the 5’ end act on posterior side whereas the genes on 3’ end act on anterior region.
- Homeotic genes are evolutionary conserved and control body specification, patterning and differentiation.
- The loss of function of any of the gene changes the body pattern and affects the development.
