The atmosphere is the part of the carbon and water cycles but absent from the phosphorous cycle. Carbon cycle depends on photosynthesis and respiration. Water cycle connects aquatic and terrestrial biomes.
Scientists so far haven’t managed to figure that out .
Answer:
Parental genotypes: RrBb, RRBB
Offspring phenotype: Running and black hair
Explanation:
Given, Running (R) is dominant over waltzing (r)
Black hair (B) is dominant over brown hair (b)
Parent 1: Heterozygous running, heterozygous black = RrBb
Parent 2: Homozygous running, homozygous black = RRBB
When they mate ( RrBb X RRBB ) :
Gametes produced by RrBb = RB, Rb, rB, rb
Gametes produced by RRBB = RB
Offspring:
RB Rb rB rb
RB RRBB RRBb RrBB RrBb
All offspring mice will be running mice and will have black hair because all the four types of genotype at least have one dominant allele for both the genes.
Answer:
The correct answer will be- Non-Mendelian inheritance (incomplete dominance)
Explanation:
Incomplete dominance is a type of inheritance pattern observed in nature in which none of the two alleles completely show their effect and produces a third type of phenotype which is different from the phenotype of both the parents.
In the given question, since the cross of red flower and white flower produces a third type of flower color known as pink during F₁ generation is the result of the incomplete effect of both the alleles.
Cross
RR (red) x rr (white) = Rr (pink)
Thus, incomplete dominance is the correct answer.
If both parents are heterozygous (Yy), there is a 75% chance that any one of their offspring will have a widow's peak.
Results - 3 yellow colored and 1 green colored. 75% - 25%.
