Can statistics be misused explain with two examples?

Answer: Statistics, when used in a misleading fashion, can trick the casual observer into believing something other than what the data shows. The false statistics trap can be quite damaging for the quest for knowledge. For example, in medical science, correcting a falsehood may take decades and cost lives.

Are statistics always true?

For the individual, it’s always “all-or-nothing”, but for the population, the estimates are still accurate. Statistical tools enable the analysis of results in research studies, so that when extrapolated to the larger population, those results are valid, helpful, and reliable.

A number line is simply a representation of the ordering of the real numbers . Usually, we mark 0 in the middle, the negative integers on the left, and the positive integers on the right: The arrow indicates that the line “keeps on going” in both directions.

Why are the plants always tall when a tall pea plant is crossed with a short pea plant?

Answer: When a tall pea plant is crossed with a short pea plant, the resultant progeny is always tall because tall is dominant trait and short is recessive trait. Therefore, dominant trait expresses itself in the progeny.

When you cross a tall pea plant with a short pea plant the offspring will be?

When a tall and short plant are crossed, all of the offspring are tall. If the offspring self-fertilize, they produce tall and short plants in a ratio of 3:1 in the next generation. Mendel’s actual counts were 787 tall:277 short plants in this generation (2.84:1 ratio).

What happens if a homozygous tall pea plant and a homozygous short pea plant are crossed?

The “TT” and “Tt” crosses both have at least one “T” allele, so they are tall plants. However, the last cross “tt” doesn’t have any “T” alleles and is short, because it is homozygous recessive . Since 1 out of 4 pea plants are short, or 1/4, the probability of a short pea plant from a heterozygous cross is 25%.

When two heterozygous tall pea plants are crossed what would the expected?

An organism’s gametes have ____________________ the number of chromosomes found in the organism’s body cells.	half

What happens when cross 2 heterozygous?

Plants with two different alleles of a gene are heterozygous. Since all the heterozygous offspring are yellow, then the yellow allele must be dominant over the recessive green allele. When two heterozygous plants are crossed, the resulting progeny mostly show the dominant phenotype.

Why would a pea plant that is heterozygous for plant height have the dominant phenotype?

Therefore even the presence of a single allele of dominant character in the gene, the dominant character can mask or suppress the recessive trait from being appeared in the phenotype. Therefore pea plant that is heterozygous for the tallness trait have the dominant phenotype.

The probability of their daughter Maria having each of the possible genotypes and phenotypes are: 25% chance that Maria will inherit a homozygous dominant trait RR and a 25% chance that she will inherit a homozygous recessive trait rr; there is also a 50% chance that Maria will get a heterozygous recessive trait Rr.

Are you 100% sure of each person’s genotype if not which ones are problematic Why?

Why? We are 100% sure of genotypes for individuals A, B, and F because they are recessive and only one genotype is possible. We are sure of individuals C and E because based on their close relationship with someone (parent or offspring) who is recessive, they must be heterozygous.

How do I find my pedigree?

Pedigrees

Determine whether the trait is dominant or recessive. If the trait is dominant, one of the parents must have the trait.
Determine if the chart shows an autosomal or sex-linked (usually X-linked) trait. For example, in X-linked recessive traits, males are much more commonly affected than females.

What is the genotype of a person who is homozygous for a cleft chin?

When someone has two copies of the same allele, they are said to be homozygous for that allele. When someone has a combination of alleles for a given gene, they are said to be heterozygous. If the woman is homozygous for cleft chin (BB), her offspring will always have cleft chin.

Which allele is always written first?
