Answer:

See the answer below

Explanation:

Long leg (L) is dominant over short leg (l) and Good muscles (G) is dominant over weak muscles (g).

Heterozygous long leg, weak muscle = Llgg

Heterozygous long leg, strong muscle = LlGg

       Llgg    x    LlGg

Offspring:

2 LLGg - Long leg, strong muscle

4 LlGg -  Long leg, strong muscle

2 LLgg - Long leg, weak muscle

4 Llgg - long leg, weak muscle

2 llGg - short leg, strong muscle

2 llgg - short leg, weak muscle

Ratio of offspring with long leg and strong muscle = 6/16 or 3/8

Ratio of offspring with long leg and weak muscle = 6/16 or 3/8

Ratio of offspring with short leg and strong muscle = 2/16 or 1/8

Ratio of offspring with short leg and weak muscle = 2/16 or 1/8

ryzh [129]

Answer:

DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin. Chromatin, in turn, loops and folds with the help of additional proteins to form chromosomes. Condensing DNA into chromosomes prevents DNA tangling and damage during cell division.

Explain Segregation of alleles, using pea plant triats in your example. Help
earnstyle [38]
Segregation of alleles happens when the pair of alleles of each parent separate and only one allele passes from each parent on to an offspring. So if you had heterozygous tall plants and mated them (Tt x Tt), they would each separate into T and t, allowing each offspring to get either a T or a t from each parent. The possible genotypes would be TT, Tt and tt.
