in a population of mustard plants, the gene that determines the height phenotype has two alleles. the allele for tall plants (t) is dominant to the allele for short plants (t). in the same population of plants, the gene for flower color also has two alleles. the allele for white color (w) is dominant to the allele for yellow color (w). a mustard plant that is homozygous dominant for both height and flower color is crossed with a mustard plant that is homozygous recessive for height and heterozygous for flower color. what are the possible genotypes of the offspring of this cross?
These crosses could result in genotypes with homozygous dominant, homozygous recessive, or heterozygous genes.
What is the genotype of this cross's progeny?The genetic makeup of the sex cells or gametes (ova and sperm) that were combined during conception to create an offspring determines its genotype. Each parent contributed one sex cell. Normal sex cells only have one copy of each gene for each characteristic.
How can the genotype of a test cross be determined?By examining the phenotypes of the offspring, the unknown genotype can be identified. If mating the unknown recessive phenotypic individual with the unknown dominant phenotype (PP or Pp genotype) results in solely dominant phenotypes (no recessive), then the unknown individual is homozygous dominant.

Why is having large leaves an advantage and a disadvantage? Link your answer to different environmental conditions (extended answer)
Answer:
Large leaves have a large surface area, which would allow them to absorb more sunlight for photosynthesis. At the same time, a large surface area would allow for a large amount of water loss.
But large leaves can cope in hot, wet, tropical climates because they counteract the daytime heat-trapping effect using transpiration – something desert plants cannot do because they cannot afford to lose that much water.
The larger the leaves, the more surface from which moisture can be evaporated. If the environment tends to be dry, the life of the plant can be threatened by losing too much moisture - therefore, the reduction in leaf size.
Explanation:
it's more difficult for them to absorb heat at night, making them more susceptible to cold temperatures.

each round of pcr doubles the number of dna molecules present in the reaction. how many molecules can be generated from two of your dna template molecules after 4 cycles?
When using the PCR method, a single DNA molecule can be amplified up to 2n times, where n is the number of cycles. As a result, a given DNA template can be amplified to 16 duplicate strands using PCR for 4 cycles.
How many DNA copies are created from the original DNA after four cycles?Each cycle results in the doubling of the number of double-stranded DNA fragments, resulting in 2n (2 to the n:th power) copies of DNA after n cycles. As an illustration, after four cycles, you have 16 copies, after twenty cycles, you have roughly one million copies, etc.
