Answer:
Natural selection, mutation, and genetic drift are random events.
Explanation:
A mechanism of evolution in which the frequencies of alleles of a population change with generations because of sampling error is known as genetic drift. It takes place in all the populations of non-infinite size, however, its influences are strongest in small populations.
Hope this helps :)
Answer:
1. genotypically
2. phenotypically
Explanation:
The genotype of an individual represents the total number and types of genes and the alleles of each gene present in the nuclei of its cells. In humans, the presence of two copies of X chromosomes makes an individual female. However, some individuals have two copies of X chromosomes but have masculine features. Similarly, some individuals have one X and one Y chromosomes in their cells. These individuals are genotypically males. But they have some feminine features. This makes them phenotypically female. Phenotype is the morphological expression of genotype.
Answer:Lisa goes in the first box Andrea’s goes in the last box there goes in 2 box and the last one goes in the third box
Explanation:
Answer:
39 chromosomes
Explanation:
A chicken is a sexually reproducing organism that undergoes meiosis to produce gametes. Meiosis is a type of cell division that involves the production of daughter cells (gametes) that have their chromosomal number reduced by half.
Hence, if the somatic or body cell of the chicken being ingested by Amanda contains 78 chromosomes, it will undergo meiosis to produce a sperm or egg that has 39 chromosomes i.e. reduced from diploid (2n) to haploid (n).
