Homodont are the animals which have similar kind of teeth. For example: lizards, frogs, dolphins, etc. Heterodont are the animals which have different kinds of teeth. For example: man, dog, rabbit, etc

Explanation:

homodont is (zoology) having teeth that are all of the same type while heterodont is (zoology) having teeth of different types (like most mammals).

Explain Mendel's law of independent assortment and how the 9:3:3:1 phenotypic ratio among the F2 of a dihybrid cross provides ev

GrogVix [38]

Answer:

Explanation:

Mendel's law of independent assortment state that two different genes assort independently in gamete formation.

To reach this conclusion, one has to do a dihybrid cross. This means that two genes responsible for different traits need to be analyzed at the same time.

1) Starting with a parental generation of a cross between two pure lines (homozygous for both genes) with different traits, a plant with yellow and round seeds (YYRR) and another with green and wrinkled seeds (yyrr). The F1 will be phenotypically homogeneous (yellow and round), and genotypically heterozygous (YyRr).

2) If the individuals from the F1 are crossed with one another, we have to do a Punnett Square to determine the phenotypic ratio of the F2.

If the genes assort independently, the F1 individuals will produce their different gametes with the same probability. Each possible gamete will appear in a 1/4 proportion: YR, Yr, yR, yr.
The 9:3:3:1 ratio is a result of analyzing the possible phenotypes that result from the dihybrid cross.

See the attached image for an illustration of the crosses in each generation and the Punnett Square.

How does the cell cycle provide evidence to support the cell theory? (Hint: All cells come from other cells).

ioda

Answer and Explanation:

All cells come from other cells. during cell division, the parent cells divide forming other cells. The cells prepare for division by multiplication of genetic material so that daughter cells will have the same number of chromosomes as the parent cell, synthesis of new organelles such as centrioles and mitochondria and building up of energy stores in form of ATP to drive the cell through the entire process.
