Biology

3 0

Answer:

Genetic engineering can be described as a process in which the DNA of an organism is modified to change its characteristics or phenotype.

DNA modification occurs when a 'gene of interest' is taken from an organism and introduced into a vector such as a plasmid. Or this gene or piece of  DNA might directly be incorporated into another organism. The gene of interest incorporated into the DNA of a host will be able to express itself.

life cycles of sexually producing organisms involve the alternation of haploid and diploid stages true/false
kolbaska11 [484]

Answer:

True

Explanation:

<em>The life cycles of sexually producing organisms generally involve alternation between the haploid and diploid generations.</em>

<u>Sexual reproduction involves the fusion of gametes - fertilization. The gametes are haploid (n) and are usually formed by the reductional division (meiosis) of diploid (2n) sex cells. </u>

Haploid gametes represent the haploid stage of the life cycles of sexually reproducing organisms.  During fertilization, the male and female gametes fuse together to form a diploid zygote. The zygote then continues to divide equationally (mitosis) and differentiates to give rise to a baby and eventually to either male or female adult organism.

A person has polydactyly (extra fingers or toes). Polydactyly is caused by a dominant allele.
Helen [10]

Answer:

1 I think, read the explanation.

Explanation:

Offspring need to carry just one dominant allele from their parents to inherit the polydactyl condition. The probability of the offspring having polydactyly is 50% (2 of the 4) and 50% not having it (normal). This can be expressed as a ratio, 2:2 which can be simplified to 1:1. - found on the internet
