Unit 6 Aca - Non-Mendelian & App of Genetics Review

Front

What is Non-Mendelian inheritance?

Back

Non-Mendelian inheritance refers to patterns of inheritance that do not follow Mendel's laws of inheritance, including incomplete dominance, codominance, and multiple alleles.

Front

Define incomplete dominance with an example.

Back

Incomplete dominance is a form of inheritance where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes. Example: Red roses (RR) crossed with white roses (WW) produce pink roses (RW).

Front

What is codominance?

Back

Codominance is a genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive. Example: AB blood type.

Front

Explain the concept of multiple alleles.

Back

Multiple alleles refer to the presence of more than two alleles for a genetic trait within a population. Example: The ABO blood group system has three alleles: A, B, and O.

Front

What is the genotype of a speckled chicken?

Back

The genotype of a speckled chicken is BW, where B represents the black allele and W represents the white allele.

Front

If a speckled chicken (BW) is crossed with a white chicken (WW), what are the possible genotypes of the offspring?

Back

The possible genotypes are 50% BW (speckled) and 50% WW (white).

Front

What is recombinant DNA?

Back

Recombinant DNA is DNA that has been formed by combining genetic material from different sources.

Front

What is the expected percentage of pink roses from a cross between two pink roses (RW x RW)?

Back

The expected percentage of pink roses is 50%.

Front

What blood types can a heterozygous type B blood individual produce?

Back

A heterozygous type B blood individual (BO) can produce blood types B and O.

Front

What is the probability of having type O blood from a cross between a heterozygous type B (BO) and a homozygous type A (AA)?

Back

The probability of having type O blood is 0%.
