Since the homozygous tall plant has two copies of the dominant allele (TT), all of its offspring will inherit one dominant allele for tallness. On the other hand, the heterozygous tall plant has one dominant allele and one recessive allele (Tt), so half of its offspring will inherit a recessive allele for shortness. Therefore, the cross will result in 100% of the offspring having at least one dominant allele for tallness. Thus, the percentage of the offspring that will be tall is 100%.

It seems like there's a typo in the question. I assume you meant to write that the homozygous tall plant is TT, not tt. So, a homozygous tall (TT) plant is crossed with a heterozygous tall (Tt) plant.

In this case, the possible offspring genotypes are:

The proportion of offspring that will be homozygous for all 10 recessive alleles can be calculated by using the formula for the probability of inheriting a recessive allele from both parents, which is 1/4 or 0.25.

Since the parents are heterozygous for each of the 10 loci, the probability of any one offspring inheriting two recessive alleles at any one locus is 0.25 x 0.25 or 0.0625. The probability of any one offspring inheriting two recessive alleles at all 10 loci is the product of the probabilities for each locus, which is (0.0625)^10 or approximately 9.77 x 10^-18.

It is important to note that the parents being heterozygous means that they have one dominant and one recessive allele for each of the 10 loci. When these parents produce offspring, each offspring inherits one allele from each parent for each locus, resulting in a genotype that is either heterozygous or homozygous for each locus. The probability of any one offspring inheriting two recessive alleles at any one locus is 0.25, because there are four possible allele combinations (homozygous dominant, heterozygous, homozygous recessive) and only one of them (homozygous recessive) results in the expression of the recessive trait.

To calculate the probability of any one offspring inheriting two recessive alleles at all 10 loci, we need to multiply the probabilities for each locus together, assuming that each locus is independent of the others. This gives us (0.25 x 0.25)^10, or (0.0625)^10, which is a very small probability. This means that the proportion of offspring that will be homozygous for all 10 recessive alleles is extremely low and may be considered negligible in practice.

If a virus infects a cell and randomly inserts many short segments of DNA containing a stop codon throughout the organism's chromosomes, it will probably cause d. manufactured proteins to be short and defective.

This is because a stop codon signals the end of protein synthesis, so if it is inserted in the middle of a gene, it will prematurely terminate the translation process, resulting in a truncated and non-functional protein. The effect would be even more severe if multiple stop codons are inserted throughout the genome, as this would greatly reduce the number of intact genes available for protein synthesis.

However, if the stop codons are not inserted into tRNA, there may be no deleterious effects on the organism's DNA or protein synthesis, since tRNA molecules are responsible for carrying amino acids to the ribosome during translation, and they do not contain stop codons.

Now, let's compare and contrast yeasts and molds with regard to their microscopic cellular morphology, macroscopic colony morphology, and reproduction:

a) Microscopic cellular morphology - yeasts are single-celled organisms that reproduce asexually by budding. They are typically spherical or oval-shaped and can range in size from 3-40 microns.

Molds, on the other hand, are multicellular organisms that consist of thread-like structures called hyphae. Hyphae grow by elongating at the tip and branching, forming a network of interconnected filaments called mycelium.

b) Macroscopic colony morphology - yeast colonies are smooth, creamy, and often appear as white or beige patches on agar plates. Molds, on the other hand, can have a variety of colony morphologies, depending on the species. Some molds form fuzzy, cotton-like growths, while others form flat, powdery colonies.

c) Reproduction - yeasts reproduce asexually by budding, in which a small outgrowth of the parent cell grows and eventually separates to form a new individual. Some yeasts can also reproduce sexually by forming mating types that fuse and exchange genetic material.

Molds reproduce asexually by producing spores that are dispersed by wind or other means. Some molds can also reproduce sexually by forming specialized structures called fruiting bodies, which contain spores.

The conditions that will lead to the highest expression of the lac structural genes are low levels of glucose and high levels of lactose

The lac repressor protein binds to the operator region of the lac operon, preventing RNA polymerase from transcribing the genes. When lactose is present in the cell, it binds to the lac repressor protein, causing a conformational change that prevents it from binding to the operator. This allows RNA polymerase to bind to the promoter and transcribe the lac genes. However, if glucose is present in the cell, it will be preferred as an energy source over lactose, even if lactose is available. This is due to a regulatory mechanism called catabolite repression, in which glucose inhibits the expression of genes involved in the metabolism of alternative sugars.

Therefore, the conditions that will lead to the highest expression of the lac structural genes are low levels of glucose and high levels of lactose. When glucose levels are low, catabolite repression is lifted, allowing RNA polymerase to transcribe the lac genes. When lactose levels are high, the lac repressor protein will be mostly bound to lactose molecules, freeing up the operator region for transcription. High levels of the lac repressor protein, on the other hand, will inhibit the expression of the lac genes, regardless of the levels of lactose and glucose. Similarly, low levels of lactose and glucose will not provide enough substrate for energy metabolism or lactose induction, respectively, resulting in low expression of the lac genes.
