Answer:

The correct answer is a geologic feature.

Explanation:

The geologic feature can be illustrated as any physical characteristic of the surface of the Earth, or of the rocks exposed at the surface, which is produced by a geologic phenomenon. Various geologic features affect the configuration of the surface of the ground and can be illustrated by the more known terms like landscapes, topography, or landforms. The distinguishable elements of the Earth crust like mountain, continent, island, valley or rift are the components of the dynamic systems of the Earth. These are the building blocks of the Earth and are together termed as geologic features.

Bond [772]

Answer:

a) The genes present on separate chromosomes exhibit indepedent assortment.

b) The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp

Explanation:

a) In a dihybrid cross, if the genes are present on the same chromosome, they will not exhibit independent assortment. The genes present on the same chromosome are called linked genes. Linked genes are inherited together. The absence of independent assortment of a linked gene gives more of parental types in F2 progeny. Therefore, if genes are not present on a separate chromosome, Mendel’s ratios deviate.

b) Alleles for tallness and purple flower are dominant. In the progeny, all the plants are tall. This means that the dominant tall plant is homozygous. With respect to flower color, the trait exhibits segregation of dominant and recessive alleles and both purple and white flower progeny are obtained. This makes both the plants heterozygous for the flower color gene.

The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp

notka56 [123]

Answer:

What role do transcription factors play in gene structure and function?

Transcription factors are proteins that bind to the upstream regulatory elements of genes in the promoter and enhancer regions of DNA and stimulate or inhibit gene expression and protein synthesis. They play critical roles in embryogenesis and development

Answer:

75%

Explanation:

If you drew a Punnett Square, you will see that the possible outcomes would be AA, Aa, aA, and aa. Three out of the four would exhibit the dominant trait.
