Term Definition
A Punnett square shows all of the following EXCEPT... The actual results of a genetic cross
In the P generation, a tall plant was crossed with a short plant. No F1 plants were short. Short plants reappeared in the F2 generation because... The allele for shortness and the allele for tallness segregated when the F1 plants produced gametes
Variation in human skin color is a result of... Polygenetic inheritance
A cross of a black chicken with a white chicken produces all "blue" offspring type of inheritance is known as... Intermediate inheritance
In the P generation, a true-breeding tall plant (dominant) is crossed with a true-breeding short plant (recessive). The probability that an F2 plant will be tall is... 75%
Which of the following exhibits codominance? AB type blood
Which of the following is a sex-linked disorder? Color dominance
Organisms that have two identical alleles for a particular trait are said to be... Homozygous
Gregor Mendel concluded that traits are... Inherited through the passing of factors from parents to offspring
How many different genotypes would result from crossing a heterozyogus tall plant with a short pea plant? 2
When Gregor Mendel crossed a true-breeding tall plant with a true-breeding short plant, the F1 plants inherited... An allele for tallness from the tall plant and an allele for shortness from the short plant
The father apart two genes are located on a chromosome, the... More likely they are to be separated by a crossover during meiosis
A man and a woman who are both heterozyogus for normal skin pigmentation (Aa) produce an albino offspring (aa). Which of the following explains why the offspring is albino? Both parents contributed the recessive allele to the offspring
How many different phenotypes would result from a cross between two heterozygous tall plants? 2
If the gene for seed color (yellow is dominant-green is recessive) and the gene for the seed shape (round is dominant-wrinkled is recessive) were crossed, which of the following would result in a plant that has green seeds that are round? yyRr
In the P generation, a true-breeding tall plant (dominant) was crossed with a true-breeding short plant. The genotype(s) of the F1 offspring would include Tt
Gregor Mendel removed the male parts (stamens) from the flowers of some plants in order to... Prevent cross-pollination
Offspring that result from crosses between true-breeding parents with different traits... Are called hybrids
if a yellow pea plant has a recessive allele for green peas, it can produce... Green peas if it crossed with a green plant and green peas if it is crossed with a green pea plant
Which of the following is not a homozygous genotype? Tt
The principles of probability can be used to Predict the traits of the offspring produced by genetic crosses
If two genes are on the same chromosome they are said to be... Linked
When Gregor Mendel crossed true0breeding purple-flowered plants with true-breeding white-flowered plants, all the offspring were purple because... The allele for purple-flowered plants is dominant
When alleles segregate from each other, they join. False
A cross between an individual with an unknown genotype but dominant phenotype and a homozygous recessive individual is called a testcross. True
An organism that is heterozygous for a particular character will generally show the recessive trait. False
Blood type in humans is determined by a single gene that has multiple alleles. True
if blue Andalusian chickens are mated, according to the idea of intermediate inheritance, 100% of the offspring are expected to be blue. False
Height in humans is the result of polygenic inheritance. True
Phenotype is determined by genotype. True
Gregor Mendel concluded that the true-breeding tall plants in the P generation passed the factor for tallness to the F1 generation. True
The plants that Gregor Mendel crossed to produce the F1 generation made up the ___ Generation P
Any gene that is located on a sex chromosome is called a... Sex-linked gene
The alternative forms of gene are called ___ Alleles
If pea plants that are homozygous for round, yellow seeds (RRYY) were crossed with pea plants that are heterozygous for round, yellow seeds (RrYy), the expected phenotype(s) of the offspring would be... Round and yellow
When two heterozygous purple-flowered pea plants are crossed, the expected genotype ratio of the offspring is... 1:2:1
