In co dominance, both alleles show. Thus, the filial, F1, generation, will most likely be white with red spots/speckles. See image below.

What happens during crossing over
CaHeK987 [17]

Answer:B) homologous chromosomes trade pieces of dna

Explanation:

Crossing over occurs between two homologous chromosome of sisters chromatid. Crossing over leads to exchange of genetic material between the two sister chromatids leading to recombination.

Which evolutionary process involves the slow addition of allelic variation that increases the hereditary diversity of population
klasskru [66]

Answer:

Mutation

Explanation:

Mutation is a change in the nucleotide sequence by addition, deletion, substitution, etc which results in the slow addition of allelic variation that increases the diversity in a population and leads to evolutionary change.

The right mutation in the allele or gene is favored by nature and it is passed in the next generation through reproduction. Mutation helps in the survival of a population in the continuously changing environment by adding new alleles that increase the fitness of the organism. So the correct answer is mutation.

Indicate whether each of the following occurs in the ER (E), Cytoplasm (C), Golgi apparatus (G), lysosome (L) or mitochondria (M
Lelechka [254]

Answer:

EELG

(1) Addition of the first GlcNAc oligosaccharides to the asparagine residue of a protein occurs in the Lumen of the Endopslamic Reticulum

(2) Synthesis of phosphatidylcholine occurs in the Endoplasmic Reticulum

(3) Degradation of misfolded ER protein ossurs in the Lysosome

(4) O-linked glycosylation occurs in the Golgiapparatus

Explanation:

1. The covalent attachment of a carbohydrate to a macromolecule such as proteins or lipids is known as glycosylation.

N-linked glycosylation is a very common form of glycosylation and it occurs in eukaryotes in the lumen of the endoplasmic reticulum.

The addition of the first GlcNAc oligosaccharides to the asparagine residue of a proteinmos an example of N-linked glycosylation.

2. Phosphatidylcholine is synthesized through the CDP-choline pathway which occurs at the cytoplasmic face of the endoplasmic reticulum. Choline entering the cell is immediately phosphorylated by choline kinase, converting choline to phosphocholine.

Phosphocholine is then converted to CDP-choline by the second enzyme in the pathway, CTP:phosphocholine cytidylyltransferase (CT).

The phosphocholine moiety is then added to diacylglycerol in a reaction catalyzed by CDP-choline:1,2-diacylgylcerol cholinephosphotransferase to complete the synthesis of phosphocholine.

3. Lysosomes are the cell organelles which are responsible for the breakdown of proteins as well as other components of the cell. Misfolded proteins are identified and transported to lysosomes through chaperone-mediated autophagy, macroautophagy and endocytosis, where they are then degraded.

4. O-linked glycosylation is a form of glycosylation that occurs in eukaryotes in the Golgi apparatus.
