Based on inheritance patterns, se_x-linked traits are present on the se_x chromosomes while autosomal traitsare found on the autosomes.
<h3>What is a dominant allele?</h3>
A dominant allele is a copy of a gene which always appears in every generation.
A pedigree is a chart that shows the inheritance of triats in generations of families.
Based on the pedigree given:
- The genotype of the individual #1 is XBXb since the offspring are XBXb and XbY
In the pattern of inheritance, all males receive their X chromosome from their mother.
Se_x-linked pedigrees differ from autosomal pedigrees because the traits are located on the se_x chromosomes.
An autosomal dominant trait require only one allele.
Based on the pedigree, the genotype of the offspring are hH, hH and hH based on the genotype of the parents.

Mitosis occurs in every cell of the body except in germ cells which are produced from meiotic cell division.
Answer:
a. Ed/eD
b. RF=0.12
Explanation:
The alleles for genes D/d and E/e are:
- D_: only on neck spikes
- dd: along back spikes
- E_: long spikes
- ee: short spikes
After testcrossing a double heterozygote (DdEe x ddee) there are 4 types of offspring, two of them much more abundant than the other two. The homozygous recessive parent can only produce <em>ed</em> gametes, so the phenotypes of the offspring depend on the gametes that the double heterozygous parent produced.
The offspring was:
- Ed/ed 79
- ed/ed 12
- ED/ed 10
- eD/ed 76
Total: 177
a) This result suggests that the genes are linked. Since recombination is a rare event, the most abundant phenotypes always come from the parental gametes, and the least abundant come from the recombinant gametes.
<u>Therefore, the genotype of the doube heterozygote parent was </u><u><em>Ed/eD</em></u><u>.</u>
b) Recombination frequency (RF) = Recombinants / Total
RF = (12+10)/177
<u>RF = 0.12</u>
Answer:
Stamen/Pistil
Explanation:
Flowering plants also called Angiosperms are a group of plants characterized by the possession of flowers used for sexual reproduction. The flowers contains the male part and female part. The male part of a flower is collectively called STAMEN while the female part is collectively called PISTIL or STYLE.
The STAMEN is responsible for the production of the male reproductive structure called POLLEN while the PISTIL is responsible for the production of female reproductive structure called OVARY. During reproduction, pollen (containing male gametes, sperm) from the STAMEN are transferred to the stigma (receptive part) of the STYLE in a process called POLLINATION.
