Answer:

A.a woman heterozygous for hair curl, a man heterozygous for hair curl will produce 25% straight hair, 75% curly hair

Explanation:

a woman heterozygous for hair curl, a man heterozygous for hair curl will produce 25% straight hair, 75% curly hair

using C as the allele for hair curl:

Cc x Cc will produce the following genotypes: CC, Cc, Cc, cc

25% will be homozygous dominant (curly hair)

50% will be heterozygous (curly hair)

25% will be homozygous recessive (straight hair)

combine the curly hair genotypes since the question asked about phenotypes which results in 75% curly and 25% straight.

Plz help! I'll give brainliest, follow, and points!!

Leni [432]

Answer:

There are many reasons why manned space probes to Saturn are simply unachievable. Getting to space is incredibly hard. The force of gravity is very hard to escape. If you wanted to, you would have to invest trillions upon trillions of dollars to create a space shuttle that may or may not explode. Second, we simply don’t have the technology to make it that far with a manned probe. Saturn is more than a billion miles away. It would take more than several years to go that far. To keep astronauts alive, entertained, and sustained is also a big challenge. In conclusion these are some reasons why a manned space probe to Saturn is unachieveable.

Explanation:

U’d better give me that brainly.

A strand of DNA that is 36 nucleotides long codes for how many amino acids?

Margarita [4]

Answer:

See answer below

Explanation:

Hi there,

Assuming this DNA strand is fully capable of being mature mRNA (5' m7G cap and PolyA tail), nucleotides lead to an mRNA codon, which is 3 nucleotides per codon. In turn, 1 codon leads to 1 amino acid. However, as a single strand, it must be capable of terminating translation, which always requires a stop codon, and thus 3 nucleotides. Hence, we must subtract this from the total amount of codons <em>first</em>.

$36 \ ncltd \ \frac{1 \ codon}{3 \ ncltd} = 12 \ codon\\12 \ codon - 1 \ codon \ = 11 \ codon\\11 \ codons\ \frac{1 A.A.}{1 \ codon} = 11 \ A. A.$

Hence, only 11 amino acids will be coded by a single DNA strand 36 ncltd long.

thanks,

In a population of white (W) and black (w) sheep, 22 out of 244 sheep are black. What is the frequency of the dominant allele in

olasank [31]

Answer and Explanation:

To calculate the allele frequency in the population, we divide the number of occurrences of the particular allele by total number of all alleles in the population Allele frequencies can be represented as a decimal, a percentage, or a fraction.

Given the population of white (W) and black (w) sheep, 22 out of 244 sheep are black, the frequency of the dominant allele in the population = 222/244×100=
