1. breeding of individuals that have genes for two different characteristics:
DIHYBRID CROSS.
We call it a dihybrid cross when we are considering a cross between two different traits.
"di" means having two traits involved (for example, trait A and trait B), the "hybrid" means that each trait will have two different alleles (for gene A: A or a; for gene B: B or b), one is dominant and the other is recessive.
2. a grid system used to predict possible combinations of genes due to random fertilization: PUNNETT SQUARE
The Punnett square is a grid system that helps us predict an outcome of a cross or a breeding experiment. We this, we can determine the probability of an offspring having a particular genotype.
This is very useful when we are considering more than one gene, making it less confusing.
3. a condition in which both alleles are dominant: CODOMINANCE
Tere are alleles that have the capacity of dominating at the same time, and when an organism is heterozygotic, both alleles are expressed.
For example, a white chicken(WW) crossed with a black chicken (BB): 100% of the offspring being WB. With this genotype, they have black feathers and white feathers. It's not a blend of colors, but a case where both are expressing.
4. when more than two alternatives exist for a gene: MULTIPLE ALLELES
Mendel thought that only two possible alternatives could exist for a gene, but there are cases that have more than 3 possibilities. Some of those can be really popular in a population while others not so much.
This happens with rabbit's fur. They can be black, brown, grayish,
Himalayan patterning or white fur.
5.a condition in which neither pair of alleles is dominant or recessive, so the traits blend in the phenotype: INCOMPLETE DOMINANCE
Some alleles are not completely dominant, and when that's the case the phenotype of a heterozygous organism will be a mix between the phenotypes of its homozygous parents.
For example:
plant 1: RR -red
plant 2: rr-white
By crossing this plants we will obtain 100% of the offspring with a color mix: pink.(genotype: Rr)
Red and white are not completely dominating so it results in a blend of colors.
Answer:
From the diagram X = <u>base pairs</u>
Explanation:
Genetic information stored within DNA is used for growth, reproduction, and cell repair. DNA, deoxyribonucleic acids, are long-chain, helical macromolecules made of specific sequences of covalently bonded monomers called nucleotides.
Nucleotides comprise:
- a 5-Carbon deoxyribose sugar,
- one nitrogenous base (adenine, guanine thymine, and cytosine)
- and a phosphate group.
Nitrogenous bases cause nucleotides to form hydrogen bonds with other nucleotides as base-pairs. The four types of bases each make the nucleotides Thymine and Cytosine (pyrimidine bases) along with Guanine, and Adenine, (purine bases). In base-pair formation, Adenine forms double bonds with Thymine, and cytosine forms triple bonds with guanine.
Answer:
Wind and moist air is drawn by the prevailing winds towards the top of the mountains, where it condenses and precipitates before it crosses the top. The air, without much moisture left, advances across the mountains creating a drier side called the "rain shadow".
The windward side of the mountain is the side of the mountain that the wind blows into. This side is where all the rain tends to be because of the air cools as it rises, making clouds. The opposite side is called the leeward side. This is where the air sinks, leaving the side much more warm and dry.
Answer:
Inside.
Explanation:
The organelle of the eukaryotes are membrane bound and performs important function. The endomembrane system in eukaryotes perform the protein synthesis, transport and sorting of proteins.
The carbohydrates are the important signaling molecules that helps in the destination of the particular protein. These carbohydrates are generally present on the inside of the vesicle membrane and determines the localization of protein.
Thus, the correct answer is inside.
