two. pink. flowers are crosswd there are 40 offspring which consist of red flowers
Answer:
The test cross is shown below
T T
t Tt Tt
t Tt Tt
The alleles shown in the vertical side (tt) are recessive and come from the male parent. The alleles TT are dominant and come from the female parent.
For the variety of offsprings to be 100% tall, the recessive parent had to be crossed with a homozygous dominant parent. If the female was heterozygous with which the cross was done,then there would be small tomato plants in the offspring generation.
Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
Explanation:
Answer:
1. Double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating groups of sugar (deoxyribose) and phosphate groups.
2. The DNA double helix. The two sides are the sugar-phosphate backbones, composed of alternating phosphate groups and deoxyribose sugars. The nitrogenous bases face the center of the double helix.
3. A nucleotide is an organic molecule that is the building block of DNA and RNA. ... A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
4. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
5. In genetics, the term junk DNA refers to regions of DNA that are non-coding. Some of this noncoding DNA is used to produce noncoding RNA components such as transfer RNA, regulatory RNA and ribosomal RNA
Hopes this helps.
If this follows the normal format for genetic trees, its neither, as a circle is a female, not a male. If it is a female, then it would be a female with one recessive gene.
