Chapter 9, Problem 6LTB
Summary Introduction
Introduction:
The organisms reproduce to give rise to their offspring. The parent passes most of its traits to the offspring. The traits that are passed from the parent to the offspring are inherited traits.

True or False: p + q = 1 is the difference of individuals alleles within a given population that is probably 100%
Many genetic disorders, such as cystic fibrosis and sickle-cell disease are due to mutations in a recessive allele. You have sampled an isolated population in which you know that the percentage of the homozygous recessive genotype (aa) is 36%. Using that 36%, calculate:
1g. the frequency of the recessive phenotype if "A" is completely dominant over "a” (round to the nearest hundredth)

- If the frequency of a homozygous recessive disorder is 1 in 10,000, the frequency of the dominant allele is ________ % and the heterozygous genotype frequency is ________ %.arrow_forwardA trait has a heritability of 0.15. This suggests: Question 5 options: The phenotypic variance is due entirely to genetic variation. The phenotypic variance is due entirely to environmental factors. The environment plays a much larger role in the phenotypic variance relative to genetics. Both genetic and environmental factors play similar roles in the phenotypic variation. Genetics plays a much larger role in the phenotypic variance relative to the environment.arrow_forwardTrue or False: "Intelligence" is a good example of a quantitative traitarrow_forward

Nearly all of the phenotypic variance for this trait in this groupof chickens is due to genetic variance.C. The trait is polygenic and likely to involve a large number ofgenes.D.
