Temka [501]

Answer:

Explanation:

1. The law of Independent assortment say that the formation of combinations of chromosomes in meiosis is random, which says that each pair of homologous chromosomes are independently separated.

2. No pair of chromosome is dependent on another pair of chromosomes.

3. In independent assortment, the cell containing allele AaBb produce equal amount of gametes AB, Ab, aB, and ab.

Describe at least two abiotic and two biotic factors found in this biome. (Desert Biome) How

Naddika [18.5K]

Abiotic: the sunlight and water.

Biotic: Plants and insects

Explanation:

Plants such as cactuses can absorb and conserve water in their roots and use the sunlight to grow taller

Insects such as Desert beetles can trap moisture in their thick exoskeletons so they are parched or burned by the sun. They sometimes bury themselves deep in the sand where it's cooler.

The abiotic factors in the desert help the biotic factors survive

The kernel color in wheat is a continuous trait determined by two additive genes, each with two alleles, that equally contribute

dedylja [7]

Answer:

Phenotypic ratio: 1:4:6:4:1

Punnett square: Below in the explanation box

Frequency distribution: In the attached files

Explanation:

<u>Available data</u>:

The kernel color in wheat is a continuous trait determined by two additive diallelic genes
The red kernels are determined by two genes and two dominant alleles (R1R1R2R2)
The white kernels are determined by two recessive alleles at the same two genes (r1r1r2r2)
R1 and R2 alleles are dominant over r1 and r2, respectively
