Someone please calculate the ratio of offspring please help pleaseeeeeeeeeeeeeeee
Over [174]

Answer:

2. 1 Pink : 1 white

3. 1 Red : 1 Pink

4. 1 Red : 2 Pink : 1 White

Explanation:

This question involves a single gene coding for flower colour in snapdragon plants. The alleles of the gene exhibits incomplete dominance i.e. the red allele (R) ia not completely dominant over the white allele (W), hence an intermediate pink phenotype (RW) is formed. Based on this, a red snapdragon will have genotype, CRCR while a white one will have genotype, CWCW. The intermediate pink phenotype will have a genotype, CRCW.

The image attached to this question shows four crosses between different traits.

In the second cross between a pink (CRCW) and white offspring (CWCW), 2pink and 2white offsprings will be possibly produced in the ratio 1:1.

In the third cross between a red (CRCR) and pink (CRCW) snapdragon, 2 red and 2 Pink offsprings will possibly be produced in a ratio 1:1.

In the fourth cross between a pink (CRCW) and pink (CRCW) snapdragon, red, pink and white offsprings will be produced in the ratio 1:2:1.

See attached image for the complete punnet square. Note that, there was a mistake in the Genotype of the last cross i.e. pink has genotype CRCW not CWCW.

The model shows the process of binary fission.
slava [35]

Answer:

<em>The correct option is B) Binary fission maintains genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell.</em>

Explanation:

Genetic continuity can be described as a fact that the daughter cells have the same amount and same type of genome as the parent cell. It includes the transfer of parental traits to children.

Binary fission can be described as a process of division which bacteria divides. Two daughter cells are produced as a result of binary fission. Each daughter cell is identical to the parent cell and hence maintains genetic continuity.

explain selective breeding, including why selective breeding is not a change caused by natural selection
SCORPION-xisa [38]
New varieties. Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.
