A dihybrid cross tracks 2 genetic traits from 2 parents.
First you need to look at all the potential combinations of each parent
Parent 1: heterozygous tall & heterozygous round Tt & Rr
Parent 2: Homozygous dominant tall & wrinkled TT & rr
(use something like foil and look at all the possible options)
Parent 1: TR , tR, Tr, or tr
Parent 2: Tr
TR . tR . Tr tr
Tr . TT Rr . Tt Rr . TT rr Tt rr
Results show that 50% of offspring will be Tall & Round and 50% will be tall and wrinkled (phenotype)
however genotype displays a 1:1:1:1 ratio as none of the genotypes are exactly the same
It equals -2 im pretty sure
Starchy foods include peas, corn, potatoes, beans, pasta, rice and grains. Starches are a more concentrated source of carbohydrates and calories than fruits, nonstarchy vegetables and dairy, but many of them are excellent sources of fiber, vitamins, minerals and phytonutrients.
Because they are organized in the "X " shape. When cells are dividing, you cant see the genetic materials.
<u>Explanation:</u>
Karyotypes are those that have a complete set of diploid chromosomes. It is a a chromosomal map. Karyotypes gets arrested during the meta phase or in the prometaphase. these are the stages of cell cycle. This happens during the condensation of the chromosomes.
During the time of mitosis, the condensation of chromosomes occurs and they will be formed as a separate individual and a visible thing. These freeze by colchicine during the stage of metaphase. This is because the organisation is in the shape of"X" and we can not visualize the genetic materials during cell division.
