What terms are frequently used in genetics?
Homozygous, heterozygous, dominant, recessive, co-dominant, incomplete dominant, alleles, multiple alleles, polygenic inheritance, test cross, Punnett squares, hybrids, carriers, ratios, percentages, locus.
Why were ratios important in Gregor Mendel's work?
The ratios were important in Gregor Mendel's works he found out that there were two types of traits namely dominant and recessive.He also wanted to find out on what ratio does the dominant and recessive traits occured in living beings.
Why are predicted ratios from a punnet square not always the actual ratiosin a populations?
Depending on other factors that influence genetics, crossing over, genetic drift and linkage as examples, certain characteristics may be more or less common in a population than demonstrated in a punnet square where the genetics of only 2 individuals are being studied and often the genetic make up is known. Further, in an entire population, the gene pool can be much more or less varied than the results seen in experiments because the gene frequencies are not known. There may be more than 2 alleles at a single locus which will also influence ratios. Also, if certain characteristics are selected for or against in a population the number of individuals with specific characteristics may be increased or diminished. The Hardy-Weinberg Principle states that an allele that is neither selected for or against will remain at the same frequency in a population. The equations are q squared+2pq+p squared=1 and p+q=1 For example. If p=.8 and q=.2 A population of 100 individuals will have 64 individuals who are homozygous for the p characteristic 4 individuals that are homozygous for the q characteristic and 32 heterozygous individuals. Note that only 4 homozygous individuals are produced in this population even though a full 20% of the alleles are required to produce this result. If p is the recessive characteristic 64% of the population will be consistently homozygous recessive because 80% of the alleles in the population are recessive. If p is the dominant characteristic 96% of the population will display the dominant trait. If q is the dominant trait 37% of the population will display the dominant trait. The larger the population the more stable the gene frequency.
What phenotypic ratios are likely to occur in crosses when dealing with two completely dominant independently segregating gene pairs when both parents are fully heterozygous?
9:3:3:1
How do mole ratios compare to volume ratios for gaseous reactants and products in a balanced chemical equation?
At constant temperature and pressure the ratios are equal.
What terms are frequently used in genetics?
Homozygous, heterozygous, dominant, recessive, co-dominant, incomplete dominant, alleles, multiple alleles, polygenic inheritance, test cross, Punnett squares, hybrids, carriers, ratios, percentages, locus.
What ratio of genotypes and phenotypes are found after two heterozygous indivividual are crossed for a trait of earlobes?
Genotypes (phenotype) 25% homozygous dominant (free earlobes) 25% homozygous recessive (attached earlobes) 50% heterozygous (free earlobes) 75% phenotypically dominant (free earlobes) 25% phenotyically recessive (attached earlobes) Ratios Genotype 1:1:2 Phenotype 3:1
Why are ratios so important in understanding how dominant and recessive traits are inherited?
you are fake
What would mating between a true breeding purple flowered pea plant and a true breeding white flowered pea plant produce?
Make a Punnet Square:White HETEROZYGOUS---WwRed HOMOZYGOUS--ww (this one is recessive because the white characteristic dominated in the heterozygous type)So:W ww Ww www Ww wwThese four are the potential types of the offspring, they will either be HETEROZYGOUS WHITE or HOMOZYGOUS RED, no homozygous white

Describe how to use the phenotype ratios to determine the percentage of offspring displaying each trait..a heterozygous gray bug Gg is crossed with a homozygous black bug gg?
i dont nkonw - - - - Ignore that person. If you are using a Punnett Square (2X2 box) then you will see that if you have a Gg (across the top) and gg (down the side) you will have Gg, Gg, gg, gg. The lowercase letters represent recessive traits and the uppercase dominant. The ratios are split into Phenotypes and Genotypes. If you have at least one dominant trait then it is considered a genotype (for this problem Gg GG). Double recessive is a phenotype (double lower case-in this case gg.) Your ratio for the above Gg, Gg, gg, gg is 2:4 (1:2) for both Phenotype and Genotype. Hope this helps!
What is the phenotypic ratio of the following dihybrid cross AaBb x AaBb?
These are the phenotypic ratios of each outcome: Dominant A and B: 9/16 Dominant A and recessive B: 3/16 Recessive A and dominant B: 3/16 Recessive A and B: 1/16
What is the expected phenotypic ratio resulting from a homozygous dominant?
I will use a simple example of Height...... T (tall) is dominant over t (short). So we have 2 ways to make a tall offspring: TT and Tt 't' is a recessive trait so it will take two 't's together to make a short offspring: tt Homozygous dominant means it has 2 of the same allele, and that this allele is the dominant one. So T T Heterozygous means it has 2 different alleles. So T t A monohybrid cross simply means "find out how this gene is inherited by the offspring". To answer the question we put the parents (TT and Tt) in a punnet square... .....T.......T T....TT...TT t.....Tt....Tt The phenotype (how they actually look) is tall for all 4 of them. TT is tall and Tt is also tall (even though they have a short 't' allele, the tall 'T' allele is dominant, making them tall anyway. Therefore the ratio of tall to short is 4:0 which can be reduced to 1:0

What are equivlent ratios?
when a number of ratios give the same answer after solving the ratios the ratios are said to be equivalent ratios
How are ratios classified?
Ratios are often classified using the following terms: profitability ratios (also known as operating ratios), liquidity ratios, and solvency ratios.
