False! <span>Territorial behavior does not extend to organisms of different species.</span>
Answer: Explanation: Human behaviour is a social perspective and hence nurturing has a pivotal role in shaping the character of a human being. Nature however is more prominent in shaping physical characteristics of an individual.
HOPE THIS HELPS ❤✌
Answer:
The dominant (light green) parent was heterozygote for the trait
Explanation:
According to Gregor Mendel in his law of dominance, an allele is said to be DOMINANT if it masks the phenotypic expression of another allele in a gene. The allele being masked is called RECESSIVE allele. In this case of a frog whose allele for light green color is dominant over the allele for brown color, the light green color allele (G) is dominant while the brown color allele (g) is recessive.
However, in a cross between that have light green frog and a brown frog, a small brown frog is produced. This is possible despite the green color being dominant because the genotype of the light green dominant parent is HETEROZYGOUS i.e. it contains both light green (dominant) allele and brown (recessive) allele.
Hence, when a gamete with recessive allele (g) is produced by the heterozygous light green frog (Gg), it mates with a recessive allele from the brown frog (gg) to produce a brown offspring (gg).
Genetic selection is the process by which certain traits become more prevalent in a species than other traits. These traits seen in organism are due to the genes found on their chromosomes. Figure 1 allies 4 genes are inherited income in various forms. Genes have more than one version or allele.
Answer:
Results in the remodeling of chromatin that can activate or inhibit gene expression
Explanation:
Alteration of histones by addition of methyl and acetyl groups are examples of chromatin remodeling complexes. These allows for the remodeling /alteration of the chromatin state to allow transcriptional machinery and other cellular processes to have access to the DNA. This way, they can either activate or inhibit gene expression. Methylation patterns inhibits gene expression while acetylation activates gene expression and so on.
