Answer:

I believe the answer is B.

Explanation:

It's not A, C and I don't think it's D.

As the Earth rotates, your region of Earth passes through both of these bulges each day. <u>When you're in one of the bulges, you experience a high tide. When you're not in one of the bulges, you experience a low tide.</u> This cycle of two high tides and two low tides occurs most days on most of the coastlines of the world.

kondor19780726 [428]

Answer and Explanation:

A gene is a section of DNA. The change in the sequence of the DNA is known as mutation.  Mutation always changes the sequence of the DNA. Sunlight can cause mutation. Sunlight produces structures named thymine dimers. Thymine dimers produce twist in the shape of DNA. These twists make DNA hard to copy, which can lead to mutation. It is essential to use sunscreen to block UVA and UVB rays to prevent thymine dimers from emerging in our cells. The US Food and Drug Agency recommends an SPF (sun protection factor) to defend against skin aging and skin cancer. X-ray radiation is a form used in x-rays. The energy level of the X-ray radiation is very high that can produce free radicals. Free radicals can steal electrons from DNA that can cause mutation. By using medical images, we can decrease exposure to X-rays. Less exposure to X-rays prevents mutation and also prevents the production of gene protein in other body parts.

In maize, liguleless (l) is recessive to having ligules (L), and dwarf (d) is recessive to tall (D). These two genes are linked
bearhunter [10]

Answer:

given,

LL║ll  and DD║dd,

after crossing over,    Ld║Ld  ×   lD║lD

LLdd × llDD

in F1 generation, they will give, LLll, DDdd, LLDD, lldd → LlDd

in eF2 generation, the offsprings will be, LLll  ×  DDdd

LLDD ,LLdd, LLDd, llDD, lldd, llDd, LlDD, Lldd, LlDd

1. yes, these genes are coupling.

2. → phenotypes of parental genes = ligules, liguleless, tall and dwarf

    genotypes of parental genes= LLdd, llDD i.e; heterozygous

 →   phenotypes of F1 generation = 25% Ligules, 25% tall, 25% ligules-tall, 25% liguleless-dwarf

      genotypes of F1 generation = heterozygous ; LlDd that is ligules-tall

3. recombination frequency= no of recombinant / total progeny × 100%

                                              = (1344+1344) / 6156+1344+1344+1156  × 100%

                                              = 2688/ 10000 × 100%

                                              = 26.88 %

that means linkage happened

and the map distance is 26.88 map unit.
