4. Use your knowledge about the relationship between nutrients and photosynthesis to explain the trends you observed in the data
Step2247 [10]

Answer:

The trends go up in the presence of nutrients.

Explanation:

There is a great relationship between nutrients and photosynthesis because photosynthesis can't occur without without the availability of nutrients. Plants uses carbon from the atmosphere which is a nutrient whereas other nutrients such as nitrogen, phosphorus, potassium etc from the soil with the help of the roots. If these nutrients are available in the surrounding, the plant produced more food during photosynthesis because these nutrients are the food of plants so the trends go up in the presence of nutrients and lowers down in the absence or lower concentration of nutrients.

) When predicting the phenotype of the offspring from a dihybrid cross, why is it so important that each gene is located in a di
Bond [772]

Answer:

a) The genes present on separate chromosomes exhibit indepedent assortment.

b) The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp

Explanation:

a) In a dihybrid cross, if the genes are present on the same chromosome, they will not exhibit independent assortment. The genes present on the same chromosome are called linked genes. Linked genes are inherited together. The absence of independent assortment of a linked gene gives more of parental types in F2 progeny. Therefore, if genes are not present on a separate chromosome, Mendel’s ratios deviate.

b) Alleles for tallness and purple flower are dominant. In the progeny, all the plants are tall. This means that the dominant tall plant is homozygous. With respect to flower color, the trait exhibits segregation of dominant and recessive alleles and both purple and white flower progeny are obtained. This makes both the plants heterozygous for the flower color gene.  

The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp
