Summary Introduction
To explain: The passage of genes in the form of alleles from parents to offspring contributes to the perpetuation of parental traits and
Concept introduction:
The transmission of traits into next generations is known as heredity and the heritable information is in the form of DNA. The offspring resemble their parents but are somewhat different; this explains genetic variation.

Imagine a recessive autosomal genetic disorder that causes death before sexual maturity. Which of the following best helps explain why such alleles persist in populations for long periods of time?
Group of answer choices
A. This allele is not heritable.
B. Some individuals with the allele have the same fitness as individuals without the allele.
C. Because they die before sexual maturity, there is no heritable variation in this population.
D. The mutation rate of this gene probably is very high, creating this recessive allele every generation
Scenario: plant species has flowers that can be red, pink, or white. Flower color is controlled by one gene with two alleles, A (p) and a (q). Red flowers are produced by AA homozygotes, pink flowers are produced by Aa heterozygotes and white flowers are produced by aa homozygotes. A recent survey of 100 of these plants found the following number of different flower colors: 75 plants with red flowers, 20 pink flowers, 5 white flowers.
Question: Among 500 plants, how many of the 'AA' genotype are expected under Hardy-Weinberg?

- Can ypu answer ALL parts to this question Pigment of chicken feathers is regulated by two genes, the gene for feather pigment C, and a gene that inhibits pigment production, I. A mother chicken, who is heterozygous for gene c, and heterozygous for gene I, is crossed with a father chicken, who is homozygous recessive for the pigment gene, and heterozygous for gene I. Inhibition is dominant to uninhibited, pigmented feathers are dominant to unpigmented feathers. The inhibitor gene (I) will prevent expression of pigmented chicken feathers. Use the letters C, c, I, and i for the genes. C is for color and I is for inhibitor Enter your answer as a list of haplotypes separated by spaces such as AB ab Ab aB. Do not write a sentence.

- The diagram below describes the relationships of genes, alleles, and loci of genetics and how a genotype manifests as a phenotype using the pea plant flower as an example. In this case, the genotype is heterozygous, meaning that the plant carries two different alleles of the gene. Think of a scenario where you have a pea plant that is homozygous recessive in flower color. Determine the phenotype of the flower color for this plant and describe how the phenotype is derived based on the information provided in the below diagram. Make sure to include the following terms, gene, allele, locus, enzyme, and gene expression, in your discussion.arrow_forwardWRITE ABOUT A THEME: INFORMATION The continuity oflife is based on heritable information in the form of DNA.

A dominant gene (D) determines white coat, and its recessive alleles (d) gives colored coat. In the presence of the homozygous recessive dd the coat color is black due to the presence of another dominant gene (B), or brown due to its recessive allele (b).
