Which cellular change in an organism could be inherited by the next generation?
Researchers cross two types of mice together, Type A and Type B. In the resulting offspring, half of the DNA comes from Type A and half comes from Type B. Why?
Two pea plants were both grown from green peas. When these plants are crossed, their offspring produce green, yellow, and white peas. What accounts for the difference between parents and offspring?
In plants, tall plants are dominant to short plants. If two heterozygous tall plants are crossed, what percent of the offspring will probably be short?
A heterozygous tall pea plant is crossed with a heterozygous tall pea plant. These two tall offspring are crossed. The Punnett square for this cross is shown below.
What can be concluded from this cross?
When an organism has more than 10 fingers or toes, the condition is known as polydactylism. Although polydactylism is rare, it is a dominant trait. If two cats that are heterozygous for polydactylism mate and have a litter with a total of 12 kittens, how many of them would you expect to have polydactylism?
Two plants are crossed, and the traits of height and color are assessed in the offspring. The following cross was conducted: TTPP x ttpp T = dominate allele for height; tall plant t = recessive allele for height; short plant P = dominate allele for color; purple p = recessive allele for color; white
Which of the following choices correctly describes the offspring?
Hemophilia is a sex-linked, recessive trait (XhXh). Which of the following describes the probability of hemophilia in the offspring of a man who does not have hemophilia (XHY) and a woman who is a carrier (XHXh)?
The table below shows the genotypes that result in four different blood types in humans.
Based on the information in the table, which of the following describes alleles IA and IB?
Why do siblings with the same biological parents sometimes inherit different combinations, or a variation of traits, such as eye color, hair type, or height?
A male and female child have three copies of chromosome 18. Although both parents are unaffected, their doctor claims that the disorder associated with having an extra chromosome 18 is the result of a chromosomal mutation in cells that carry inherited material. Which argument supports this claim?

Based on the inheritance pattern, what are all the possible genotypes for individual 6?
Albino individuals lack all pigmentation so that their hair and skin are white. This family tree shows that albinism
The table provided below shows the heredity of fur color for rabbits. The black fur color is dominant to white fur. The parent generation, first generation of offspring (F1), and second generation of offspring (F2) is shown below.
What conclusion can be drawn from the genetic information above?
The Punnett square below depicts a type of cross known as a monohybrid cross, and it is similar to crosses performed by Gregor Mendel.
Which of the following arguments can NOT be defended using the evidence in this Punnett square?
Students studied Mendel's laws of segregation and independent assortment. They created a Punnett square to show a cross between a homozygous furred mouse (FF) and a homozygous furless mouse (ff). The students then created a Punnett square for a cross between two heterozygous F1 mice.
Which of the following questions could be answered using the information from the Punnett squares above?
Use the cross below to answer the following questions:
