Answer:
X linked inheritance is one of the mechanisms of the inheritance which is associated with the mutation of the gene present on the X chromosome.
The characteristics of the X linked recessive inheritance that must be observed in the pedigree analysis will be-
1. X linked trait is always passed from the mother to the sons (females to males)
2. The males (XY) are usually affected by the gene as only one copy of the recessive gene in males can show its effect.
3. Females are the carrier of the disease but they are not affected by the condition.
<span>The answer would be: a) Frost-wedging happens when water freezes and breaks rocks.
Normally, the volume of a substance will become lower when the temperature drops but when water becomes ice it will expand. Water that freezes into ice can produce a high pressure from the expansion of their volume. If enough water fills a joint in a rock, the rock might get enough force to fractured or break. This will happens in the area that has a freeze-thaw cycle like in the polar climate.</span>
<span>The offspring received one allele from each parent. The alleles were separated during gamete formation before they were passed to the offspring. The offspring received the G allele for green pod color from one parent, and they received the g allele for yellow pod color from the other parent. Green pod color is dominant, resulting in the offspring having the green pod color.</span>
So, one at a time: I'm attaching a picture of the punnet squares (hard to make on the computer (and you can simplify the ratios down):
4. HHnn x hhNN
All offspring are HhNn; 100% same genotype (HhNn); 100% phenotype of short, normal
5. HhNn x HhNn
Genotypes and ratio:
HHNN(1): HHNn(2): HhNN(2):HhNn(4):HHnn(1):Hhnn(2): hhNN(1):hhNn(2):hhnn(1)
Phenotypes and ratio:
Short normal (9): short colorpoint(3):Long normal (3): Long colorpoint (1)
6. TtNn x ttnn
Genotypes and ratio:
TtNn(4):Ttnn(4):ttNn(4):ttnn(4) (which is 1:1:1:1)
Phenotypes and ratio:
Tabby normal (1): Tabby colorpoint (1): Stripless normal (1): stripless colorpoint (1)
7. hhNn x hhNn
hhNN(4): hhNn(8):hhnn(4)
short normal (12): short colorpoint (4)
