  1. In diploid organisms, having two homologues of each chromosome can be beneficial if one allele of a gene encodes a nonfunctional protein. Can haploid organisms survive having nonfunctional alleles? Explain your answer.

Answer #1

Diploid organisms have two sets of chromosomes whereas haploid organisms have a single set of chromosomes. Allele is an alternative form of gene and located on the same site on the homologus chromosomes. A haploid organism with a non functioning gene will no longer survive. A haploid organism is having only one allele in each gene. It is the only copy of that particular gene.If that allele in a gene is non-functional, no other allele is there in the haploid organisms to mask the non-functional allele and hence the organisms cannot be able to survive.

The yeast Saccharomyces cerevisiae can grow as haploid or diploid cells. You have two haploid yeast strains that each carry mutations that make them unable to grow when galactose is the sole available source of energy. One strain has a deletion of the entire region of the genome between the GAL1 and GAL10 genes (DUAS). The other strain carries a mutant allele of GAL2 that produces no functional GAL2 protein. You cross these two strains together to get diploid progeny....

Diploid cells contain two copies of each chromosome. Why are there two copies of each? Because one copy will be kept in the nucleus and one copy will be used in the cytoplasm. Because the DNA is a double-helix. Because each parent contributes one copy of their offspring. Because the chromosomes are duplicated in case one gets damaged.

Red, Blue and Green are three genes found on the same chromosome. Each gene has two alleles: R or r, B and b, and G and g, respectively. The somatic cells and gametes of a person that is heterozygous for the alleles of all three genes are studied to understand the relationships between the three genes. It is found that the dominant alleles for Red and Green is on the person’s paternal chromosome, but the dominant allele for Blue is...

1) Suppose that there’s a gene that produces a protein that colors the fur of horses.  There are two alleles of this gene.  One allele produces a functional protein that has a brown color.  The other allele also produces a functional protein, but it has a grey color.  If a horse is heterozygous for this gene, it has the ability to make both “brown fur” proteins and“grey fur” proteins (meaning that its overall fur color looks “muddy”).  Based on this information, you can deduce that...
