Sadie is the oldest of six siblings. All of her brothers and sisters are related, but they all look different from each other and their parents. What evidence would support the claim that the genetic variation among Sadie's siblings is from new combinations of genetic material?
crossing over during meiosis
solar radiation
segregation of chromosomes
insertion mutation
Cystic fibrosis is an example of a genetic disease caused by the deletion of a nucleotide. What is the term for this type of mutation?
translocation
chromosomal
substitution
frameshift
Organisms like coral and fungi can reproduce both asexually or sexually. Zane claims that these organisms have an advantage over organisms that can only reproduce sexually. What habitat characteristics would be most advantageous for these types of organisms?
a slowly changing environment with many mates
a slowly changing environment with few mates
a rapidly changing environment with many mates
a rapidly changing environment with a lack of mates
Two parents have the genotype Gg for a genetic disorder caused by a dominant allele. What is the chance that any of their children will inherit the disorder?
25%
50%
75%
100%
Which of the following conclusions was a result of Mendel's observations?
Organisms that give rise to purebreds are genetically superior.
Organisms that have intermediate features are self-pollinating.
Organisms inherit two copies of each gene, one from each parent.
Organisms that self-pollinate do not have "either-or" features.
A plant that is homozygous for red flowers is crossed with a plant that is homozygous for white flowers. In the case of incomplete dominance, the flowers of the offspring will be what?
red only
white only
pink
red and white spotted
Blake has an AB blood type and his sister has type O. Blake is unsure of his mother's blood type. Still, he knows his mother's parents have blood genotypes of AA and O. Using Punnet squares, what would be the genotypic ratio of offspring blood type possibilities if Blake's father and mother had another child?
3:1
2:2
2:1:1
1:1:1:1
