Summary Introduction
To describe:
The pattern of simultaneous inheritance of two traits if each of the traits is controlled by a separate gene with only two alleles, one dominant and one recessive.
Introduction:
The inheritance of traits includes the transfer of the characters of genes from one generation to another. The traits include the expression of genes for seed color of pea pod where the dominant gene color is yellow and recessive is green seed color. The smooth shape of pod is dominant over the wrinkled variety.

Which of the following defines polygenic inheritance?
An inheritance pattern in which one allele is not fully dominant over another, so the heterozygous phenotype is an intermediate blend of the two homozygous phenotypes
An inheritance pattern in which the full and separate phenotypic effects of two alleles are apparent in heterozygous individuals
An inheritance pattern in which a single gene affects multiple traits
A pattern of inheritance in which multiple genes affect one trait
Determine the mode of inheritance:
Homozygous recessive die from fatal disorder, when a specific enzyme activity is absent. Heterozygous exhibit wild type phenotype but have intermediate level of gene expression resulting in 1/2 of the wild type enzyme activity when compared to Homozygous normal non-carriers. Based on the levels of gene expression ALONE, the mode of inheritance is?‐---------------

Shape of the face.
Most facial characteristics are affected by many different genes acting together
(multiple factors or polygenic inheritance). For this trait we have simplified the nature
of this trait by assuming it is the result of a single gene. Oval shape is dominant (needs

- Color-blindness (c) is a sex-linked recessive trait, while normal color vision (C) is dominant: If two normal-visioned parents have a color-blind son, what are the parent's genotypes? ~What are the chances that their children will be color-blind?arrow_forwardYou possess two alleles for each of your genes. (One from the paternal side and one from the maternal side in each homologous pair of chromosomes.) In simple inheritance, having at least one dominant allele (form of the gene) means you will display the dominant phenotype, and the only way to display the recessive phenotype is to have two recessive alleles. For example, individuals with the genotypes RR and Rr can roll their tongue (into a U shape). If you cannot roll your tongue, then you know with certaintly you have the genotype rr. If you can roll your, you would write your genotype as R- (R followed by a dash since you might not know if you are RR or Rr, but either way, you display the dominant phenotype because the first letter is capital.) Match the following traits with their proper genotype using the letters provided in the lab handout. left arm on top when crossing arms blue eyes no middigital hair widow's peakarrow_forwardWhat explains how the parents in a family both have the same eye color, but some of their children have a different eye color? Assume for this example that eye color is determined by a single gene. ● One parent is homozygous dominant, and the other homozygous recessive for a gene that controls eye color allowing some of the children to express a different trait. O The parents are both heterozygous for a gene that controls eye color allowing some of the children to get two recessive alleles. O The parents are both homozygous dominant for a gene that controls eye color allowing some of the children to get two recessive alleles. O One parent is homozygous dominant, and the other heterozygous for a gene that controls eye color allowing some of the children to express a different trait.arrow_forward
- Given that there is a trait determined by the alleles A and a, where A is dominant, i.e., the presence of A determines the phenotype. Assume that two parents have four children, and assume that nothing is known about the parents. One of the four children shows the recessive condition (so its genotype is aa) and the other three show the dominant trait (so their genotype is either Aa or AA). What can we conclude about the parents? Group of answer choices - at least one parent shows the dominant trait - Both parents are heterozygous - Both parents have at least one recessive allelearrow_forwardIn humans, the gene for brachydactyly (abnormally short fingers) is a dominant gene.

- Curly hair is due to a dominant allele in humans. Straight hair is a recessice allele. the heterozygous condition produces wavy hair, a. phenotype that appears as a blend of the two alleles. This is an example of which of the following patterns of inheritance. a) Simple dominant b) Sex linkage C) Multiple allele d)Incomplete dominancearrow_forwardIn humans, brown eyes are dominant to blue eyes, and the ability to roll your tongue is dominant to not being able to roll your tongue. If a mother who was heterozygous for eye colour and homozygous recessive for tongue rolling had a baby with a father that was heterozygous for both traits, what is the probability that their child would have blue eyes and could roll their tongue?arrow_forwardColor-blindness is a recessive disorder found on the X chromosome. There can be individuals that are carriers for the trait (Of the two X chromosomes they have, only one has the colorblindness allele while the other is normal. In this pattern of inheritance, all carriers are female). We express sex-linked traits with respect to our sex chromosomes. For example, if the allele for colorblindness is "b" and the allele for normal color vision is "B", then a female carrier is X x. II III IV 6. What are the two sex chromosomes for females?
