Answer:
A) 48
B) 96
C) 48
D) 48
Explanation:
Attached is a table summarizing the number of chromosomes and chromatids in the different stages of mitosis and meiosis in humans who are described as 2n = 46.
For the organism which is described as 2n = 48, substitute 46 in the table for 48 to get the appropriate figures.
Endogenous processes - Under surface of the earth.
Exogenous processes - Above the surface of the earth.
Lithosphere - Is broken into tectonic plates.
Plates - made of thick slabs of rock, compose the crust/ocean crust .
7 major plates - Pacific, North America, South America, Eurasian, Antarctic, indo-Australian
Temperate grasslands have hot summers and cold winters. Summer temperatures can be well over 100 degrees Fahrenheit, while winter temperatures can be as low as -40 degrees Fahrenheit. They typically have between 10 and 35 inches of precipitation a year, much of it occurring in the late spring and early summer.
Answer:
bacteria, archaea, plants, protists, animals, and fungi,
Explanation:
Answer:
The ratio of blue to white offspring in the progeny is 4 blue : 12 white.
Explanation:
<u>Available data:</u>
- The dominant allele K is necessary to synthesize blue flower pigment
- K is inhibited by the dominant allele D
- Plants with the genotype K- D- will not produce pigment (and their flowers will be white)
Cross: testcross for (Kk Dd) plants
Parental) KkDd x kkdd
Gametes) KD kD Kd kd
kd kd kd kd
Punnet square) KD Kd kD kd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
- Whenever D is present, it inhibits the expression of the K gene, so every plant with the dominant D allele will be white. This plants´ genotype is kkD- or K-D-.
- Whenever D is absent and K is present, every plant with genotype K-dd will be blue.
- The recessive form for K and D genes will express white-flowered plants, with genotype ddkk
F1) Progeny genotype: 4/16 KkDd, white-flowered plants
4/16 Kkdd, blue-flowered plants
4/16 kkDd, white-flowered plants
4/16 kkdd, white-flowered plants
The ratio of blue to white offspring in the progeny is 4 blue : 12 white.
Blue-flowered plants: 4 Kkdd
White-flowered plants: 4 KkDd + 4 kkDd + 4 kkdd
