Answer:
A virus attaches itself to cells and usually reprograms them to reproduce itself. Also, unlike bacteria, most viruses do cause disease. Some virus-caused diseases include the common cold, AIDS, herpes, and chickenpox
Explanation:
False it actually the genetic disease of having more fingers or toes than there should be... its also not just humans but cats and dogs as well
Answer:
(i) Small island
(ii) Large island
(iii) Option-3
Explanation:
In the given question, the three population of the Anoles Lizards migrated to three islands of different size.
(i) Genetic drift is a random or by the chance process which changes the frequency of the alleles in the population. The change in the frequency of the allele can be easily observed in the small population therefore the small island with the smallest size of the population will have the strongest genetic drift.
(ii) Heterozygosity of alleles that is with a dominant and a recessive allele is the result of the exchange of alleles in the population. The size of the population is finite on the island therefore the heterozygosity is not introduced in the small population but in a large population, it can be introduced as the mating is random.
(iii) The genetic drift is strongest on the small island therefore L2 allele can be easily influenced by this effect. The selection coefficient is very small that is 0.002 therefore no mutation is occurring on the island.
Answer:
Incomplete Dominance
Explanation:
Incomplete dominance is a phenomenon in which the alleles of two genes are not completely dominant over each other and so when they are present at the same time in an organism (heterozygous for that gene) the organism will have an intermediate phenotype that is a combination of both phenotypes.
For example: The flower color in Snapdragon can have three different genotypes as well as phenotypes. The flowers can be red, pink or white depending on their genotype. The allele for red flower (R) is incompletely dominant over allele of white flower (r). A plant with genotype RR will be red flowered and that with rr will be white flowered. However, if a plant has genotype Rr (intermediate), then the flowers will be white in which no allele was dominant over the other and both showed their effect giving a combination of two colors as Pink flowers.
Same is the case with the mating between white and black hen, where offspring was grey in color. This grey was a combination phenotype of two phenotypes.
