A cross occurs between a chicken with white feathers and a chicken with black feathers. This results in offspring with some black feathers and some white feathers. What type of inheritance is this?
2.
Mendel's law of segregation was based on the separation of alleles in the garden pea during
3.
Consider a dihybrid cross between two rabbits LlBb x LlBb. What are the phenotypic ratios of the offspring? (L = long ears l = short ears; B = black b = white)
4.
A man who is a carrier for cystic fibrosis marries a woman who is a carrier for cystic fibrosis. What is the percentage probability that this couple will have a child with cystic fibrosis?
5.
A group of individuals have lived for generations on an island. Their average height is 5 feet 2 inches. Eventually, ships stop by the islands bringing more fruits, vegetables and meats to their diet and more food overall. While the islanders continue to marry islanders and produce children, over generations the average height of the islander population reaches 5 feet 6 inches. What was most likely the main factor in this change?
6.
Sickle cell disease is the result of one gene abnormality. When two recessive alleles occur, sickle cell disease is inherited. The disease results in misshaped hemoglobin. What type of molecule is hemoglobin?
7.
A female who is AO (iA, iO) mates with a male who is BO (iB, iO). What possible blood types can their children inherit
8.
The probability of an event, such as inheriting a recessive allele, is ½. The probability of inheriting a second recessive allele is ½ . What, then, is the probability of inheriting two recessive alleles?
9.
In Mendel's monohybrid cross, short stem trait becomes recessive in Fi generation. It will express in F2 generation only when/in:
10.
Blood type in humans is the result of multiple alleles. Blood type is also an example of which type of inheritance pattern?
11.
When the phenotype of the heterozygote is intermediate between phenotypes of the two parental homozygote, then this relation is termed as
12.
When a single gene affects two or more traits, this phenomenon is termed as:
13.
If a child has O type of blood group and the father has B type, then the genotype of the father will be
14.
When two Independent events are occurring simultaneously like in dihybrid cross, the ratio of each Joint phenotypic combination can be obtained by
15.
Distinct the genotypic ratio of the cross between Tt x Tt plants:
16.
Polygenic inheritance refers to which of the following conditions of inheritance?
17.
A man who is a carrier for cystic fibrosis marries a woman who is a carrier for cystic fibrosis. The couple in the above scenario has four children. How many of their children will have cystic fibrosis?
